Psychological aspects of Pashto Landay
Authors: Zaheer Zahir Shah
Published: January 2023

Pashto landay is a great and delicious asset of folk literature that has not only gained fame and importance in the Pashtoon community, but is now emerging day by day as a good and beautiful poem in the field of international literature. Pashto landay of Pashto oral literature is a short and meaningful poem that is free from rhyme, but in terms of weight it is equal to the fifth long syllable of free poetry. The stress comes on the fourth syllable of each column. The first hemistich is nine syllables and the second one is thirteen syllables and ends with an independent sound. In this brief article it hasn’t discussed on the framework of landay, but the content of landay which are the voice of the heart of the Pashtoon people are analyzed from the perspective of psychology. Pashtoons who have suffered many hardships throughout their lives have been deprived of the lawful pleasures of life due to the influence of their imposed culture and all their deprivations have been pushed from the conscious to the unconscious. As a result, they have told their deprivation in landay as a poem and made themselves happy and encouraged. These problems and deprivations are different and discussing them all is beyond the scope of an article. In order to attract the attention of researchers to this topic in the future, some obvious aspects related to human psychology have been discussed.

MOTIVE OF ESSAY WRITING

The poem is discussed from two aspects one is the form and the other is the content. In Pashto literature there have been many discussions about poetry framework in general, but its content has not been discussed as much as it should be. In today's modern literature the psychological aspect is relatively new and important, so this aspect is stronger than others in Pashto literature, because the Pashtoon are more oppressed than any other people, so this was the reason why I wrote this article. It has come so that readers of other languages will be informed about the deprivations of Pashtoons' lives by reading this article.

Non-Governmental Organization/Non-Profit Organization Impact on Education Policy in Ghana
Authors: Okine Sarah Ayikai
Published: January 2023

Non-Governmental Organizations/Nonprofit Organizations (NGOs/NPOs) are progressively becoming an essential source for government agencies in education worldwide. Developing countries such as Ghana have opened the way through regulations and policies for NGOs/NPOs to contribute to the educational system. Nevertheless, perceived threats and confrontations hinder their ability to support the Ministry of Education (MoE) and partner leaders to fulfill their duties in assisting the government in realizing comprehensive universal primary education. This qualitative case study responded to stakeholders’ perceptions of NGOs/NPOs influence on Ghana’s educational system to better comprehend the dynamic and power of NGOs/NPOs on education in Ghana’s rural communities. The study used the Advocate Coalition Framework; advocacy coalition theory brings together sub-systems and political actors interested in policy changes or shifts for a common goal to organize effective ways for the changes or shifts. Ten volunteers participated in the interview focusing on schools in rural Ghana. The findings indicated NGOs/NPOs are a complementary authority to MoE and partner leaders. According to the data analysis and findings, MoE and partner leaders need to form an intentional coalition with NGOs/NPOs for interventions to define the role descriptions and functions of programs and projects to achieve the interventions. NGOs/NPOs resources for MoE and partner leaders are necessary to improve the quality of teaching and learning in schools. Decision-making bodies of MoE and partner leaders may benefit from this study in policymaking for interventions of programs and projects supervision, implementation, and monitoring and evaluation for positive social change.
Association Between Therapeutic Interventions and Quality of Life in People With Autism
Authors: Movsessian Taline , Osoba Tolulope A
Published: January 2023

Research exploring the association of autism interventions with the quality of life (QoL) of adults with autism spectrum disorders was scarce. Although a multitude of interventions are used to target a specific challenge facing the individual with autism, their correlation with achieving a better QoL is largely unknown. We conducted a cross-sectional, correlational survey study to determine the association between seven interventions—behavioral, social, mental health, daily living skills (DLS), vocational, mindfulness, and medications—and the QoL of adults 18 years and older with autism with no intellectual disability (ID) living in Canada. A national sample of 182 autistic adults or proxy reports completed the survey that used the WHOQOL-BREF to measure subjective QoL. Behavioral, mental health, and medications were the most frequently used interventions (67%, 71.4%, and 82.4%, respectively). QoL was lower across all domains of the WHOQOL-BREF compared with the general population. Hierarchical multiple regression analysis showed that characteristics, such as autism severity, being female, and older age negatively predicted QoL across all domains except for the physical domain, whereas being in a relationship positively predicted social QoL explaining 35.2% of the variance. Of the seven interventions used, behavioral therapies and receiving mental health support consistently predicted a better QoL across all domains, except for the environment domain where only mental health support was a significant predictor. Our findings suggest prioritizing provision of behavioral and mental health interventions to adults with autism and inform future research to evaluate their effectiveness in QoL outcomes as an end goal.
Hardships, Motivations, and Resiliency: Case Study of Health Implications of 2022 Russian Invasion on Ukrainian Resistance Members
Authors: Hanson-DeFusco Jessi
Published: January 2023

The 2022 Russian full-scale invasion of Ukraine caused millions of Ukrainians to flee. Yet most citizens continue to reside in the country, playing critical roles in the Ukrainian resistance. Today the Ukrainian fighting force includes trained military and police as well as citizens who either were conscripted or volunteered to take part in national war efforts. This mixed-method study conducted in Spring 2022 presents data collected from 79 respondents in a semistructured survey, using snowball sampling. Data analysis examined individual self-reported motivations, attitudes toward the conflict, resilience, quality-of-life hardships, and scaled perceived stress. Results indicated that Ukrainian resistance members face extreme physical threats, are displaced, separated from family, and experience high levels of stress, especially anxiety, sadness, and anger. Yet individuals tend to experience significantly less overall Perceived Symptoms Scale symptoms if they have intrinsic motivations linked to patriotic ideologies, altruism, and preventing genocide. Bootstrap regression modeling indicates that familial relationship with their nation reduces symptoms by approximately 13%. Comparatively, being extensively separated from family is linked to 21% higher stress. These motivations appear to provide a sense of purpose and source of resiliency despite the health risks associated with resisting a full-scale foreign invasion. My purpose with this article is to represent respondents’ motivations and experiences during the war and to help inform future public health policy and program services that many Ukrainians may need to recover.
Condom Use Self-Efficacy Score and Risky Sexual Behavior among High School Students in Southern Ethiopia
Authors: Bassore Gizachew Kebede , Danawi Hadi , Marc Linda G. , Kennedy Chinaro
Published: January 2023

There is emerging evidence of a rise in new human immunodeficiency virus (HIV) infections in Ethiopia. This may partly be explained by an increase in risky sexual behaviors among high school adolescents. The current study was conducted to explore the association between a set of predictor variables (comprehensive HIV knowledge and condom use self-efficacy score) and an outcome variable of risky sexual behavior among high school adolescents in the Angacha District of Southern Ethiopia. The study employed a quantitative cross-sectional design to answer the research question. Primary data were collected using a self-administered questionnaire from 374 participants using a stratified random sampling technique. Descriptive statistics and bivariate and multivariate logistic regressions were computed using SPSS Version 25. The prevalence of risky sexual behavior among school adolescents was 30.04/per 1000. The Cronbach’s Alpha for condom use self-efficacy score (CUSES) was 0.79. The association between HIV comprehensive knowledge and risky sexual behavior was not statistically significant. A statistically significant association was found between CUSES and the risky sexual behavior of the student, P = 0.048, OR =2.23, 95% CI [1.007, 4.925] when the covariates were held constant. The mean CUSES for males (M = 3.44) was significantly higher than females (M = 3.22), U = 14523.5, P = 0.025, η2 = 0.016). Policy decisions to revitalize school-based adolescent sexual health promotion to empower adolescents with life skills are needed to sustain the gains of HIV/AIDS control and enhance social change in the country.

Cervical cancers only rarely metastasize to the ovaries. The proportion of cases presenting with ovarian metastases ranges between 0.6 and 1.5%.Histologically Adenocarcinomas are more likely to metastasize to the ovaries than Squamous cell carcinoma’s, 5-8% of cervical adenocarcinoma vs 0.4-1.3% of Squamous cell carcinoma’s metastasized to the ovary. The incidence in those with adenocarcinoma was associated more closely with tumour size whereas it was more associated with clinical stage in SCC. Here we present a case report of Squamous cell carcinoma of the uterine cervix with ovarian metastasis staged according to FIGO 2018 as stage IVA and treated with Radical radiation therapy with concurrent weekly chemotherapy followed by Intra-cavitary Brachytherapy and Adjuvant chemotherapy.

Inadvertent injection of autologous blood in both subdural and intrathecal spaces following EBP is extremely rare. Case reports describe SSH or SAH after attempted EBPs. This illustration depicts combined subdural and subarachnoid collection after EBP for post dural puncture headache (PDPH)(from a lumbar spinal drain), 6 days after 40 ml of autologous blood was injected in the “epidural space” at the same spinal level as the preceding spinal drain. The T1-weighted sagittal (Panel A) and axial (Panel B) MR image of the spine demonstrates a subdural collection of blood (white arrows) extending from T12-L1 to sacral level and subarachnoid collection of blood (asterisks) extending from L3-4 to the termination of the thecal sac at S2. Mild backache and neck stiffness is not uncommon after EBPs. Worsening back pain with radicular symptoms suggests blood in the subdural or subarachnoid spaces which can result in meningitis, arachnoiditis, lower extremity weakness and radiculopathy.

60-year-old diabetic patient, followed for Hodgkin's lymphoma who presented to the emergency room for diffuse abdominal pain in a febrile context. The biological examination showed hyperleucocytosis with a high CRP (320mg/l). An ultrasound was performed showing a voluminous lateralized right pelvic collection confirmed by an abdominal CT scan. The patient benefited from a percutaneous drainage objectifying a purulent liquid. The cytobacteriological examination came back in favor of E.coli. The patient was put on ceftriaxone-based antibiotic therapy. Evolution is marked by a decrease in fever with persistence of high CRP. A CT scan showed a clear regression of the collection with the appearance of intraosseous air bubbles in the iliac wings without cortical involvement, suggesting emphysematous osteomyelitis.

Ossification of the posterior longitudinal ligament (OPLL) is a condition of abnormal calcification of the posterior longitudinal ligament, mostly found in men, the elderly, and Asian patients, hence the name Japanese disease. The cervical spine area is the most typical location (75%), but can also affect the thoracic (15%) or lumbar (10%) spine. The spinal cord can be compressed by this lesion, which can cause neurological deficits. The treatment of choice for patients with symptomatic OPLL is surgery to relieve spinal cord compression. We report an exceptional case of lumbar ossification of the OPLL in a Moroccan patient.

La gastroenteritis aguda es procedencia de un proceso inflamatorio gastrointestinal causado por enteropatógenos como: virus, bacterias y en menor proporción por parásitos siendo el principal problema de salud que se vive en todo el mundo, constituyéndose como la segunda causa de mortalidad en niños. La frecuencia relativa de cada patógeno va a variar según el grupo etario, la ubicación y si el historial del caso es a nivel comunitario u hospitalario. Analizar las evidencias científicas sobre epidemiologia y diagnóstico de enteropatógenos asociados a gastroenteritis aguda. El tipo de estudio de esta investigación fue de manera descriptiva de diseño documental, se realizó una búsqueda en revistas indexadas en las diferentes bases de datos como PubMed, Google Académico, SciELO, SciencieDirect, Dialnet y ELSEVIER. Se incluyeron artículos originales, de revisión sistemática, tesis de pregrado y doctorales. Los niños menores a cinco años de edad son los más afectados por gastroenteritis aguda (96%) ocasionado en mayor proporción por rotavirus y las bacterias que son transmitidos por el mal almacenamiento de alimentos, consumo de agua no potable y la zona geográfica rural, su diagnóstico se da en una consulta médica para su respectivo procedimiento de análisis siendo el método de reacción en cadena de la polimerasa el más empleado en los laboratorios. La gastroenteritis aguda es muy común y se presenta con mayor relevancia en niños, la causa va a depender de la manipulación y consumo que tenga con los alimentos también va a interceder el hábitat donde se encuentre el paciente.

La enfermedad por COVID-19 que es causada por el nuevo coronavirus SARS-CoV-2 muestra una marcada heterogeneidad en su curso clínico, variando desde cuadros asintomáticos hasta formas potencialmente letales como síndrome de distrés respiratorio agudo (SDRA) o falla multiorgánica. Algunos factores se han asociado a peor pronóstico de COVID-19, como la edad avanzada, presencia de comorbilidades y algunos parámetros de laboratorio, cuyo reconocimiento resulta de gran importancia para tratar de predecir su evolución. Se realizó una revisión sistemática en bases de datos científicas como PubMed, SciELO, Elsevier, Google Scholar, Organización Panamericana de la Salud (OPS), Organización Mundial de la Salud (OMS), Redalyc, Springer, libros, y reportes de salud. El objetivo principal de esta revisión fue investigar sobre los marcadores inflamatorios y severidad de COVID-19. Se observó en la mayoría de las fuentes una disminución de los valores medios de la hemoglobina y del conteo global de los linfocitos, del conteo de plaquetas sobre todo en los casos graves; así como aumento de los analitos como lo son el dímero D, Procalcitonina, PCR, LDH, Interleucina 6 entre otros. En la presente investigación de tipo revisión bibliográfica se demostró que es importante determinar los diferentes tipos de marcadores de la inflamación para determinar la gravedad de la enfermedad en pacientes que presentan COVID-19, y en base a estos resultados considerar su ingreso a hospitalización o a su vez la necesidad del ingreso a la unidad de cuidados intensivos.

La actual pandemia de la enfermedad por coronavirus (COVID-19), producida por una cepa mutante de coronavirus SARS-CoV-2 tiene predilección por el árbol respiratorio, una vez que penetra genera una respuesta inmune anormal de tipo inflamatorio con incremento de citoquinas, provocando agravar al paciente. La trombocitopenia es una reducción en el número de plaquetas circulantes en sangre, representando un nivel crítico en la hemostasia. Las cifras estándar en el torrente sanguíneo en un recuento de plaquetas son de 150.000 a 450.000/ul, cuando el valor muestra un descenso de 150.000/ul en las plaquetas es indicativo de trombocitopenia. En este estudio se tomó en cuenta los dos tipos de púrpura trombocitopénica: púrpura trombocitopénica idiopática (PTI) y púrpura trombocitopénica trombótica (PTT). El objetivo de este trabajo investigativo fue basado en establecer la asociación de púrpura trombocitopénica y la infección por enfermedad de coronavirus y de acuerdo a esto se utilizó una metodología de diseño documental, de tipo informativa - descriptiva. Se obtuvieron resultados, mayores casos de PTT que de PTI. La edad, sexo, cargas virales, enfermedades autoinmunes, enfermedades virales como COVID-19, problemas pulmonares, entre otras conllevan a esta patología. Los métodos diagnóstico más frecuentes son: hemograma completo, ensayos de actividad ADAMST13, hisopado nasofaríngeo, coagulograma básico.  En conclusión, se analizaron variables importantes referentes a la fisiopatología de púrpura trombocitopénica asociada al COVID-19. Los principales factores de riesgos y demográficos en la púrpura trombocitopénica asociada en pacientes COVID-19. Y, los métodos esenciales de diagnóstico de la púrpura trombocitopénica asociada en pacientes COVID-19.

Extreme color variation in the Peregrine Falcon (Falco peregrinus) in Patagonia
Authors: Ellis David H. , Saggese Miguel D. , Franke Alastair , Nelson R. Wayne
Published: January 2023

From fieldwork begun in 1979 and continuing intermittently until the present, we show the range in variation in pigmentation of Peregrine Falcons (Falco peregrinus) native to the Patagonian region of South America. This variation nearly equals the full range in Peregrine Falcon color variation for all races worldwide. The pallid morph is paler than any other peregrine, and in extreme southern Patagonia, most dark or normal morph adults are as pale or paler than extremely pale arctic peregrines from northern Asia and North America. In the forests of the southern Andes Mountains, there are richly colored (i.e., with deep red-brown ventral background pigmentation) falcons that approach or equal the darkest peregrines anywhere. Some juvenile peregrines are more deeply red-brown ventrally than any other juveniles worldwide. Most important, we introduce the hypothesis that non-pallid adult color variants are largely segregated by habitat type. By inference, this suggests that adjacent ecotypes may represent different subspecies.

Un lente de islas para la ornitología argentina
Authors: Balza Ulises
Published: January 2023

Many examples of important ecological processes come from island ecosystems. This is due to its limited space and biodiversity, as well as to the fact that its geological history and connection with continents are usually known in detail. However, in Argentina there is still a rudimentary knowledge about the birds that depend partially or totally on island ecosystems. In this work, I review and discuss ornithological information on the island ecosystems of Argentina, arguing that they may be a priority for future research and management. Knowing the biodiversity of the islands, their particularities and their current conservation status could be relevant in the future to avoid local extinctions. Moreover, islands can provide refuges for unique taxa and areas where invasive species management may be more feasible. Furthermore, understanding island ecology can be useful for studying and conserving other ecosystems, both terrestrial and aquatic, which is highly relevant in an increasingly fragmented landscapes.

El Carpinterito Ocráceo (Picumnus nebulosus) en Argentina: distribución histórica, hábitat y situación actual
Authors: Bodrati Alejandro , Pagano Luis , Di Sallo Facundo G.
Published: January 2023

The Mottled Piculet (Picumnus nebulosus) is considered near-threatened globally and threatened in Argentina. In Argentina there are a few records on the banks of the Uruguay River in the extreme northeast of the province of Corrientes and in the southeast of Misiones, but the species was practically ignored since its discovery in 1961, and little is known about its demographic situation, distribution, habitat use, and threats. We compiled available information on the species based on bibliographic searches, museum consultations and online databases, and we present data from field campaigns in 11 localities. Based on museum material from individuals collected 60 years ago, we extend the known historic distribution in Argentina, to the south, by a factor of five; however, no new records were obtained in central-eastern Corrientes. Although it was previously suggested that the Mottled Piculet is associated with bamboo (Guadua sp.), we believe that conserved understory/midstory with lianas may be more important than bamboo. The lack of protected areas that include the species, its small range, the constant degradation of its habitat and the construction project of the Garabí-Panambí dam could lead to the extinction of the Mottled Piculet in Argentina during the next decades. It is important to carry out surveys to the south of the modern localities to clarify its current distribution, and study aspects of the species ecology to generate efficient management plans.

Alloparental behavior includes a wide range of situations, from occasional fostering to adoption. It is usually the result of brood parasitism, brood adoption or brood mixing, but also due to nest switching. Interspecific alloparental behaviors are less widespread, but there are no key differences in mechanism of underlying behaviors. Some South American grebes are found sympatrically, and some of them usually reproduce on mixed colonies. Here we describe different conspecific and interspecific alloparental behaviors involving Silvery Grebe (Podiceps occipitalis), White-tufted Grebe (Rollandia rolland) and the critically endangered Hooded Grebe (Podiceps gallardoi). We discuss the implications of temporary adoption and potentially ‘true’ adoption, in particular for Hooded Grebes. Our observations show that alloparental behavior is possibly widespread among Neotropical grebes, and in the case of the Hooded Grebe we hypothesize that alloparental intraspecific feeding of non-related juveniles prior to migration could help to increase juvenile survival.

The Delta of the Paraná River, one of the most important wetlands in South America, harbors subtropical and temperate bird species. Although this region is key for biodiversity conservation, aspects such as species composition and conservation status, and their relationship with vegetation types are poorly known. Here we described bird richness and composition of this area, with emphasis on the relationship between vegetation type and the presence of key bird species. We compiled systematic studies conducted during the 2007-2020 period and performed new surveys to elaborate a checklist of bird species and assess completeness. We reviewed a total of 12 studies distributed along five landscape units and nine vegetation types. We recorded 245 species, though the species accumulation curve indicates that the number of species could be even higher for the area. Most species were recorded in freshwater marshes, watercourses and grasslands in Entre Rios. We identified 14 (5.7%) threatened species (e.g., Spartonoica maluroides, Limnoctites rectirostris and Sporophila palustris), most of them registered in grasslands and freshwater marshes. To our best knowledge, the list of species is the most comprehensive one for the area, showing that 23.7% of all bird species known for Argentina. Our results suggest the importance of freshwater marshes, watercourses and grasslands as key vegetation types for birds.
Aportes al conocimiento de las aves asociadas a los bosques de bambú de la Amazonía peruana

Bamboo forests are an important microhabitat for Neotropic birds. In the Amazon, the study of these communities began in the 1980s. However, only general aspects of the association of birds to bamboo forests were found, and a response to how an almost monospecific floristic environment can sustain numerous species of birds remains unknown. In this work, we provide information about the natural history of the main bird species of the bamboo forest in the southeastern Peruvian Amazon. Between 2004 and 2011, we conducted fieldwork in the bamboo forest dominated by Guadua sarcocarpa, locally known as Pacal, combining censuses from points and mist-netting. We characterized feeding habits, and foraging and nesting strategies of 28 bird species considered indicators of bamboo. Most of the indicator species (86%) were insectivorous, three omnivorous, and one nectarivorous. “Pacal” insectivorous indicator bird species use space differently, allowing a large number of species to coexist in a monospecific vegetation structure. All bird species nested in the understory, and most species built open nests, indicating that the bamboo is offering good nest protection. Two bird species are globally threatened. Three bamboo bird species were described from previous species, and one has been discovered less than 15 years ago, showing that the birds of bamboo are only just beginning to be known.
Historia biogeográfica del Gran Chaco: modelado de nicho y filogeografía de la Monterita Cabeza Negra (Microspingus melanoleucus) (Aves: Thraupidae)

The Gran Chaco, which is part of the diagonal of Neotropical open formations, is a fundamental region to test hypotheses of past connections among the Atlantic Forest, the Amazon and the Yungas. The aim of this study was to evaluate whether the Gran Chaco was fragmented by expansions of wet forests during Pleistocene climatic oscillations, which could have connected the Atlantic Forest and the Yungas’s southern sector (Tucuman-Bolivian Forest). To test the hypothesis, we studied an endemic bird of the region, the Black-capped Warbling Finch (Microspingus melanoleucus). We conducted phylogeographic analyses employing DNA sequences of nuclear and mitochondrial markers, as well as ecological niche modeling (ENM) for the present and past periods (Last Interglacial, Last Glacial Maximum and Middle Holocene). The results indicated high gene flow among the studied populations, with no geographically restricted lineages. The niche models showed a relatively conserved distribution range across historic periods, although they suggested for the present, and particularly for the Mid Holocene, a lack of habitat suitability along a geographic diagonal from northeast to the southwest of the study region. These results supported temporal habitat stability in the Gran Chaco ecoregion, and did not support the hypothesis of expansions of wet-forests that could have fragmented the region and linked neighboring domains such as Andean and Atlantic forests.

We report information from museum specimens, online databases, bibliographic records, and field data that show colonization of the Argentinean provinces of Entre Ríos and Corrientes (Argentinean Mesopotamia) by Chaco Chachalacas (Ortalis canicollis). This colonization probably started during the first decades of the 20th Century, and this cracid is currently expanding its range towards the Uruguay River basin.
Del Monte al Chaco: eBird revela la migración del Piojito Trinador (Serpophaga griseicapilla)
Authors: Gorleri Fabricio C. , Roesler Ignacio
Published: January 2023

The Straneck’s Tyrannulet (Serpophaga griseicapilla) is a small migratory flycatcher that completes its annual cycle within southern South America, and which appears to breed exclusively in Argentina However, as a recently described species, historical records are lacking, and several aspects of its migratory ecology are still poorly studied. In this study, the new records of the Straneck’s Tyrannulet available in the eBird database are analyzed to describe the species migration and phenology. Species distribution models (Random Forests) and abundance models (GAMs) were used to predict its (1) seasonal distribution, (2) habitat associations, and (3) migratory phenology. Further evidence that the Straneck’s Tyrannulet is an endemic breeder of Argentina, with the southern Monte being the species’ main breeding region, is provided. After breeding, the Straneck’s Tyrannulet migrates to the north and overwinters in the plains of the Argentine Mesopotamia (from March to October) and the Chaco region (from May to October), where it is mostly sighted in shrublands near watercourses. The species makes a notable migratory passage in autumn and spring (with peaks in mid-April and mid-September) through the arid Chaco and the sierras of Córdoba and San Luis, suggesting a potential migratory route. Also, further evidence of the enormous value of new citizen science databases for reconstructing migratory and phenological patterns in birds is presented. The qualitative and quantitative increase of these records will enable more precise and detailed ecological insights.
¿Es la tasa de captura de juveniles una medida confiable de la productividad del Fiofío Silbón en el Bosque Andino-Patagónico?
Authors: Gorosito Cristian A. , Cueto Victor R.
Published: January 2023

Productivity is an important parameter in the study of avian population dynamics, and is commonly estimated through the number of young captured with mist-netting. However, this approach may not represent a true measure of local fledgling productivity. Several studies have reported a close relationship between the number of young captured and fledgling productivity for several bird species from Europe and North America, but to our knowledge this relationship has not been studied for Neotropical species. Our objective was to evaluate the relationship between fledgling productivity and young capture rate for White-crested Elaenia (Elaenia albiceps chilensis). We captured birds with mist-nets, and carried out intensive nest monitoring during three breeding seasons. We found a close relationship between young capture rate and fledgling production. We also observed that fledglings stayed with their parents for almost the entire time between leaving the nest and the moment they dispersed from the territory they hatched in. Thus, we are confident that annual young abundance estimated by mist-netting reflects local fledgling  productivity. This relationship needs to be evaluated in other Neotropical bird species to generalize the results presented here.
Evaluación de parámetros reproductivos de la Gaviota Cocinera (Larus dominicanus) en una de las mayores colonias de Patagonia, Argentina

Published: January 2023

Knowledge of the breeding biology of birds is relevant to understand aspects of their life histories and interpret how they respond to the increasing changes they face globally. The breeding biology of the Kelp Gull (Larus dominicanus) was evaluated at the Punta Tombo Natural Protected Area, Chubut, site of one of the largest colonies in Argentine Patagonia. During 2016 and 2017, 160 and 161 nests were monitored, respectively. The median laying date was similar in both years (November 19, 2016 and November 21, 2017). The mean clutch size was similar between years (2016: 2.09 ± 0.67 and 2017: 1.99 ± 0.67). The incubation period was 26.47 ± 3.43 and 27.76 ± 2.06 days for 2016 and 2017, respectively. Hatching success was higher in 2016 than in 2017 (1.23 ± 0.89 vs. 0.81 ± 0.99, respectively). The chick-rearing stage spanned 9 and 10 weeks in 2016 and 2017, respectively. The data obtained suggests that predation was the main cause of nest loss. Breeding success was significantly higher in 2016 than in 2017 (0.53 ± 0.73 vs 0.34 ± 0.66 chicks per nest, respectively), and individuals that started breeding earlier had significantly higher breeding success. The information obtained constitutes a baseline for monitoring the reproduction of the Kelp Gull in this protected area and to identify possible changes in response to anthropogenic changes in coastal environments of Chubut.
Interacciones intraespecíficas durante la alimentación en grupo en la Gaviota de Olrog (Larus atlanticus)
Authors: Zumpano Francisco , García Germán Oscar
Published: January 2023

In this study, we analyzed the intra-specific interactions that occur between individuals of Olrog’s Gull (Larus atlanticus) while foraging in groups outside the breeding season. Interactions were studied by analyzing behavioral observations of foraging individuals (n=171) at the Mar Chiquita Coastal Lagoon (Buenos Aires Province, Argentina). We recorded a total of 98 trophic displacements events and 70 kleptoparasitic events, in which successful attacks were 95% and 24% respectively. Juveniles and males initiated de interactions in the 77% of the trophic displacements and 65% of the kleptoparasitic events. The attacks were “with physical contact” in the 55% and 32% of the trophic displacements and kleptoparasitic events, respectively. The main tactic response for both intra-specific interactions was “avoiding”. The probability of occurring a kleptoparasitism event was related to the prey size. We conclude that juveniles and males were the main initiators of the interactions studied and that the main difference between them was the success rate. This study is the first to analyze and discuss the intra-specific interactions that occur between individuals of Olrog’s Gull. Understanding their feeding behavior is important to discover new aspects of natural history and to provide background information for a threatened endemic species.
