Question: "Motherland" and "The Life of Birds" are both examples are which type of film?
Context: The Life of Birds is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 21 October 1998. Phenology is the study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation).  The word, coined by the Belgian botanist Charles Morren around 1849, is derived from the Greek φαίνω ("phainō"), "to show, to bring to light, make to appear" + λόγος ("logos"), amongst others "study, discourse, reasoning" and indicates that phenology has been principally concerned with the dates of first occurrence of biological events in their annual cycle.  Examples include the date of emergence of leaves and flowers, the first flight of butterflies and the first appearance of migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies.  In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Flowers of the Motherland () is a 1955 Chinese black-and-white film, which was produced by Changchun Film Group Corporation.  The movie follows the primary school students' life after China's founding. Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, in many cases leaving the seeds damaged and not viable.  Granivores are found across many families of vertebrates (especially mammals and birds) as well as invertebrates (mainly insects); thus, seed predation occurs in virtually all terrestrial ecosystems.  Seed predation is commonly divided into two distinctive temporal categories, pre-dispersal and post-dispersal predation, which may involve different strategies and requirements and have different implications at the individual and population level.  Nevertheless, regardless of timing, seed predation has great implications for plant population dynamics.  To counterbalance effects of predation, plants have evolved defenses such as seed morphology (size, shape, toughness) and chemical defenses (secondary compounds such as tannins and alkaloids) to defend against their seed predators.  However, as plants have adapted defenses to seed predation (e.g., chemical compounds), so have seed predators adapted to plant defenses (e.g., ability to detoxify chemical compounds).  Thus, many interesting examples of coevolution arise from this dynamic relationship. The Monza ampullae form the largest collection of a specific type of Early Medieval pilgrimage ampullae or small flasks designed to hold holy oil from pilgrimage sites in the Holy Land related to the life of Jesus.  They were made in Palestine, probably in the fifth to early seventh centuries, and have been in the Treasury of Monza Cathedral north of Milan in Italy since they were donated by Theodelinda, queen of the Lombards, (c. 570–628).  Since the great majority of surviving examples of such flasks are those in the Monza group, the term may be used to cover this type of object in general. This list of fictional penguins is subsidiary to the list of fictional birds and is a collection of various notable penguin characters that appear in various works of fiction.  It is limited to well-referenced examples of penguins in literature, film, television, comics, animation, and video games. The symbol of a bluebird as the harbinger of happiness is found in many cultures and may date back thousands of years.  One of the oldest examples (found on oracle bone inscriptions of the Shang Dynasty, 1766-1122 BC) is from pre-modern China, where a blue or green bird ("qingniao") was the messenger bird of Xi Wangmu, the 'Queen Mother of the West' who began life as a fearsome goddess and Immortal.  By the Tang Dynasty (618-906 AD) she had evolved into a Daoist fairy queen and the protector/patron of "singing girls, dead women, novices, nuns, adepts and priestesses...women [who] stood outside the roles prescribed for women in the traditional Chinese family".  Depictions of Xi Wangmu often include a bird—the birds in the earliest depictions are difficult to identify, and by the Tang Dynasty, most of the birds appear in a circle, often with three legs, as a symbol of the sun. Anchiornis is a type of small, four-winged paravian dinosaur.  The genus "Anchiornis" contains only the type species "Anchiornis huxleyi", named for its similarity to modern birds.  "Anchiornis" fossils have been only found in the Liaoning Province of China, in rocks dated to the late Jurassic period, about 160 million years ago.  "Anchiornis" is known from hundreds of specimens, and given the exquisite preservation of some of these fossils, it became the first Mesozoic dinosaur species for which almost the entire life appearance could be determined, and an important source of information on the early evolution of birds. Birdman of Alcatraz is a 1962 biographical drama film starring Burt Lancaster and directed by John Frankenheimer.  It is a largely fictionalized version of the life of Robert Stroud, a federal prison inmate known as the "Birdman of Alcatraz" because of his life with birds.  In spite of the title, much of the action is set at Leavenworth Prison, where Stroud was jailed with his birds.  When moved to Alcatraz he was not allowed to keep any pets. Motherland (እናት ሀገር "ˀənatə hägär ") is a 2010 independent documentary film directed and written by Owen 'Alik Shahadah.  "Motherland" is the sequel to the 2005 documentary "500 Years Later".
