Black-capped Parakeet
Pyrrhura rupicola
Small dark parakeet of tall mature forest of the humid lowlands and lower slopes of the Andes. Dark green and long-tailed, with black scaling around the neck. Often travels in small, tight flocks that rocket through the canopy, calling loudly. Listen for even-pitched screeching, fairly low for a parakeet; voice similar to Rose-fronted Parakeet. Formerly known as Rock Parakeet.
分类信息
Swiss naturalist Johann Jakob von Tschudi described the species in 1844.<p>There are two subspecies of Pyrrhura rupicola:<p>P. r. rupicola can be found in western South America and is common in Peru. P. r. sandiae can be found in the extreme west of Brazil, south-east Peru, and northern Bolivia. Commonly called the Sandia conure in aviculture, it features narrower scalloped feathers on the neck and breast and a lack of scalloped feathers on the hindneck.<p>The black capped parakeet may breed with the green cheeked parakeet in the wild.<p>"Black-capped parakeet" has been designated the official name by the International Ornithologists' Union (IOC). It is also known in the pet trade as black-capped conure or rock conure.

行为
Black capped parakeets are highly social birds and communal roosters. In the wild, they flock with up to 30 birds at a time. During breeding season smaller groups of families can be found. Black capped parakeets enjoy bathing. In the wild black capped parakeets are canopy feeders. The black capped parakeet lives up to 30 years in captivity.<p>Black capped parakeets reach sexual maturity between 1 and 3 years old. They roost in small groups during breeding season. A clutch generally has 4 to 7 eggs. They have a 24-day incubation period, followed by 7 to 8 weeks of parental care. Black capped parakeets have a breeding season from February to March.<p>Wild black capped parakeets eat a variety of fruits, nuts, berries, and vegetation. They may also raid farmers crops.<p>Black capped parakeets are listed as near-threatened in the wild on Appendix II. The primary cause of their habitat loss is the deforestation of the Amazon Basin. It is estimated that between there will be a 13.7% and 15.5% loss of habitable land over 18 years. A decrease in forest buffers alongside streams, amnesty for land owners guilty of illegal deforestation before 2008, and a reduction in the amount of private land that must be kept as forest contribute to this problem.

Cayenne Jay
Cyanocorax cayanus
Large jay of humid forest and edges including savanna and premontane forest in the tepui region. Combination of size and black-and-white plumage unlike any other species in range. Moves through forest in noisy groups but can be hard to see well. Sometimes accompanies foraging flocks of oropendolas and caciques, feeding on flowers and fruit. Calls include a variety of whistles and grunts.
Lesser Crested Tern
Thalasseus bengalensis
Elegant medium-sized tern with a slender yellow-orange bill and black crown. Can be confused with Great Crested Tern; note proportionally longer, more orangey bill on Lesser Crested. Also note gray upperwing, which separates it from Sandwich Tern. Gray rump and tail are diagnostic if seen well. On juveniles, note dull legs, secondaries with dark centers, and a weakly patterned upperwing. Strictly coastal, usually found on beaches and estuaries. Call a noisy “kerrrick.”
Sunda Collared-Dove
Streptopelia bitorquata
Medium-sized pinkish-brown dove with bright red eyes. “Collar” is black with a white upper margin. Favors mangroves and other open forests and forest edge, occasionally venturing into areas of human habitation; generally uncommon throughout much of its range. Gives a deep throaty purr.
