Cundinamarca Antpitta
Grallaria kaestneri
A rather plain antpitta known only from a small area of Colombia’s eastern Andes, southeast of Bogotá. Plumage is dull brown with small white streaks on the underparts, a slightly paler belly, and a faint eyering. Distinguished from Tawny Antpitta by its much darker plumage, streaked (not scaled) underparts, and habitat preferences. Inhabits cloud forest understory, and mostly stays on the ground, though may come up to a low perch to sing. Song is three short whistles that ascend slightly in pitch.
Identification
Overall the Cundinamarca antpitta is a dull olive-brown bird with white streaking on the underparts. The feathers of the bird’s back are an olive-brown that are fringed with a thin band of sooty-black, giving the bird the appearance of possessing very faint barring. This fringe vanishes from the rump and uppertail coverts, and the antpitta’s tail is slightly darker than its back. The wings are a richer brown than the rest of the upperparts, while the underwing is a buffy cinnamon. The underparts are mostly olive-brown fading to a dull white on the bird’s belly. The sides and flanks are covered with dull white streaking. The face and throat are a dull olive and slightly mottled, and the bird has pale streaking behind the ears. The Cundinamarca antpitta measures about 15 to 16 cm (6 to 6 in) long. The sexes are similar in appearance.<p>While no similar antpittas have been found to share the Cundinamarca antpitta’s habitat, making it unlikely to be confused with another species, it is distinguished from the similar Santa Marta antpitta by being darker overall and by range.<p>The Cundinamarca antpitta’s song is brief at roughly one second in length and is high-pitched for a member of its genus; it has been described as a “whir, whee-whee.” This song most frequently is composed of three whistled notes that increase in pitch, with a slight pause after the first note; sometimes, the final note is left unsung. The bird’s call is a two-note whistle with the first note piercing and at a higher frequency than the second.
Taxonomy
The Cundinamarca antpitta was first discovered by Peter Kaestner, an American diplomat and amateur ornithologist who later became the first birder to see 10,000 bird species anywhere in the world. The genus name Grallaria is from the Neo-Latin grallarius, meaning "stilt-walker". The specific name kaestneri is in reference to the bird's discoverer, Peter Kaestner. The Cundinamarca Antpitta's common name refers to the Cundinamarca Department, within which the entire population of the species is believed to reside.<p>When first described, the Cundinamarca antpitta was believed to be most closely related to the Santa Marta antpitta; however, it has since been suggested to be more closely related to the brown-banded antpitta and Urrao antpitta, due in part to details of the immature's plumage. The Cundinamarca antpitta has no known subspecies.

Cooper's Hawk
Astur cooperii
Small to medium-sized hawk with relatively short rounded wings and rounded tail. Adults are gray above with pale orange barring below; immatures are browner and streaky. Very similar to Sharp-shinned Hawk, but larger with bigger head. Also note deeper, slower wingbeats. Breeds in forested areas; more common in suburban areas than Sharp-shinned Hawk. Feeds mainly on birds captured in flight. Often stalks feeders in search of prey.
Jungle Nightjar
Caprimulgus indicus
Gray-brown nightjar of wooded, open grassy, and scrubby areas; not restricted to jungles. Intricately patterned, with a golden patch behind the ear (often not visible on a resting bird) and pale tan spots on the wings. Male shows bright white patches near the wingtips and on the edges of the tail that are buffy-brown in females. Similar Savanna Nightjar is much more densely patterned and lacks the tan wing spots; Savanna also tends to roost on the ground, versus in trees for Jungle Nightjar. Song is utterly alien-sounding and unique: a long series of bouncing “pooKIHpooKIHpooKIH” notes, comparable to a cartoon laser gun.
Cape Starling
Lamprotornis nitens
A medium-sized iridescent blue-green glossy starling that lacks dark ear-patches and has greenish flanks and belly, giving it a more uniform appearance than the “blue-eared” starlings. Pairs and small groups occupy high-altitude grassland, Karoo, and savanna, including drier habitats than other glossy starlings. The species feeds on the ground and in trees on fruit and insects; often it scavenges from people. It gives a rolling “turrreaau” flight call and harsh “karrr” alarm notes. Similar “blue-eared” starlings differ from Cape Starling by being smaller and having blue-magenta flanks and belly that give them a less uniform appearance.
