January 30, 2018 – Red-crested Finch or Red Pileated-finch (Coryphospingus cucullatus)
These tanagers are found in a large range in central South America, with small populations in Peru, the Guianas, and northeastern Brazil. Little is known about their diet, but they forage on the ground and in low vegetation, forming mixed-species flocks with seed-eating birds outside of the breeding season. Breeding between November and February, they build cup-shaped nests from small twigs, vine stems, dry grasses, lichens, and other materials.
January 28, 2018 – Cochabamba Mountain-finch (Poospiza garleppi)
These tanagers are found only in a small part of central Bolivia. They forage on the ground and in low shrubbery, feeding on seeds, insects, and possibly potatoes. Breeding during the rainy season, females build nests in shrubs, laying one or two eggs. They are classified as Endangered by the IUCN due to habitat loss and degradation.
January 12, 2018 – Golden-hooded Tanager (Tangara larvata)
These tanagers are found from Central America south to Colombia and Ecuador. They mostly eat fruits and berries, along with insects and other invertebrates. While feeding on large fruit they often hang upside down, tearing off pieces with their beaks. Both parents build the cup-shaped nests in trees, bushes, or sometimes in bunches of green bananas. Males usually bring food to females as they incubate the eggs. Older chicks may also help feed their younger siblings. Pairs often lay more than one clutch of eggs per year.
January 10, 2018 – White-winged Diuca Finch (Diuca speculifera or Chionodacryon speculiferum)
These finches spend all year in the high Andes of Peru, Bolivia, Argentina, and Chile. Their diet is not well known, but is probably made up of seeds and arthropods, much like that of other closely related species. They spend most of their time foraging in pairs or small groups in puna grasslands and are currently the only bird known to commonly build nests directly on glacial ice. The bulky nests, made from sticks and lined with grass, have been found on stony hillsides as well as on the Quelccaya glacier in Peru.
December 29, 2017 – Cinnamon Tanager (Schistochlamys ruficapillus)
These tanagers are found in parts of Brazil, Paraguay, and Argentina. They eat mostly fruit and seeds, along with some insects, foraging alone or in pairs. Little is known about their breeding behavior as only a single nest has been recorded with a clutch of two eggs.
September 10, 2017 – Yellow-shouldered Grosbeak (Parkerthraustes humeralis)
These birds in the tanager family are found in parts of Colombia, Bolivia, Brazil, Ecuador, and Peru. Foraging alone, in pairs, or in mixed-species flocks, they eat insects, seeds, and possibly flowers and other plant matter. Little is known about their breeding habits, though juveniles have been observed foraging with adults in June in northeastern Peru. Though they are classified as a species of Least Concern by the IUCN, their population is thought to be decreasing due to habitat loss.
August 9, 2017 – Yellow-tufted Dacnis (Dacnis egregia)
These tanagers are found in parts of Colombia and Ecuador. They are sometimes considered a subspecies of the Black-faced Dacnis, which looks quite similar except for its white rather than yellow areas of plumage. They eat fruits and probably some arthropods, often feeding on the berries of Miconia trees. Little is known about their breeding habits.
