Hooded Capuchin
Sapajus cay
French: Sapajou du Paraguay / German: Azara-Kapuzineraffe / Spanish: Capuchino de Azara
Other common names: Azara’s Capuchin
Taxonomy. Cebus apella cay Illiger, 1815,
left bank of the Rio Paraguai, Paraguay.
This species is monotypic.
Distribution. SE Bolivia (departments of Tarija and Santa Cruz), N Argentina (provinces of Jujuy, Salta, Formosa, and Chaco), Brazil (W of the Rio Parana— through the N of Mato Grosso State into SW Goias, and Mato Grosso do Sul states), and Paraguay (E of the Rio Paraguay as far as the mouth of the Rio Parana). Its range to the west in Bolivia is poorly known; it would seem that it is absent from the Bolivian Chaco as it is from the adjacent Paraguayan Chaco west of the Rio Paraguay. There is no evidence to date that the Yungas populations in SE Bolivia and NW Argentina are continuous with the population in Brazil and Paraguay to the E.
Descriptive notes. Head—body 40-45 cm,tail 41-47 cm; weight 3.3-5 kg. The Hooded Capuchin is a small, short-limbed species without sexual dimorphism, typified mainly by its prominent dark dorsal stripe. It is very variable in color but generally quite pale. Its crown is pale to blackish brown with two small tufts like horns. The Hooded Capuchin differs from other robust/tufted capuchins in that hair on the back of the neck and dorsal proximal two-thirds of the tail is slightly burnt brown and dorsal parts of the body (shoulders, front of the upper arms, saddle, rump, and thighs) are grayish-brown. Forearms, hands, wrists, lower legs, and feet are blackish. Eyes, nose, and mouth are variably surrounded by white hairs. There is a small white beard, and a dark line extends down from the ears to the jowls and under the chin.
Habitat. Subtropical humid and semi-deciduous forests. In southern Bolivia and north-western Argentina in the Yungas Biogeographic Province, Hooded Capuchins are found in seasonal subtropical submontane (laurel) and montane forests up to elevations of ¢.1500 m. In eastern Paraguay, they occur in dense humid semi-deciduous forest and gallery forests in areas of thorn scrub and savanna, but not in the Chaco west of the Rio Paraguay except possibly a small region of the southern wet chaco of the country. In the Pantanal of Mato Grosso, they occur in seasonal semi-deciduous forests and gallery forest.
Food and Feeding. Diet of Hooded Capuchins is composed largely offruits, leaves and animal prey. Studies in El Rey National Park, Argentina, in the north-western part ofits distribution found seeds and fruits in diets during the wet season (November—March) and a significant preponderance (70%) of succulent leaf bases, peduncles of inflorescences, and infructescenses of epiphytic Bromeliacae (notably Aechmea distichantha but also the larger Tillandsia maxima and Vriesea tucumanensis) throughout the year. In the Pantanal, Hooded Capuchins visit flowers and lick nectar of the vine Combretum lanceolatum (Combretacae). When feeding in vegetation along riverbanks in the Pantanal, shoals of fish, notably the fruit-eating characid Brycon microlepis, follow capuchins to pick up debris they drop. Fruit of Guarea cf. guidonia (Meliaceae) and Zanthoxylum riedelianum (Rutaceae) particularly attract capuchins and fish.

Status and Conservation. CITES Appendix II. Classified as Least Concern on The [UCN Red List (as Cebus cay). The Hooded Capuchin is widespread but poorly known. It occurs in Barita, Calilegua, and El Rey national parks in Argentina, Noel Kempff Mercado National Park in Bolivia, Pantanal Matogrossense and Serra da Bodoquena national parks in Brazil, and Caaguazu, Cerro Cora, and Ybycui national parks in Paraguay.
