Yungas Sparrow

Rhynchospiza dabbenei

Attractive sparrow found along the western edge of the Andes in northwestern Argentina, barely reaching over the border into Bolivia. Note the chestnut head stripes, dark smudge between eye and bill, and black and white mustache. Similar to Chaco Sparrow, with which it was formerly lumped as Stripe-capped Sparrow, but is larger with more extensive black on the face, rustier wings, and a different voice. Inhabits open, grassy habitats with scattered trees and low scrub. Song is a slow series of wheezy chirps.

识别特征

The Yungas sparrow is larger than its former "parent" R. strigiceps. Its upper parts are brown with darker streaks and varying amounts of rust and gray. It is pale gray below blending to buff on the flanks and in the vent area. The head is gray with chestnut crown and postocular stripes, black lores, and a white moustachial stripe.

分类信息

The Yungas sparrow was previously classified as a subspecies of Rhynchospiza strigiceps, which was at that time called the stripe-capped sparrow. Before that, Rhynchospiza had been subsumed into genus Aimophila. A 2009 publication restored the genus Rhynchospiza and a 2019 publication split R. dabbenei from R. strigiceps. Based on the 2019 publication, in June 2020 the South American Classification Committee (SACC) of the American Ornithological Society (AOS) accepted R. dabbenei as the Yungas sparrow and renamed R. strigiceps Chaco sparrow. The International Ornithological Congress (IOC) followed suit in January 2021.

Chucao Tapaculo

Chucao Tapaculo

Scelorchilus rubecula

Fairly common to common in native temperate forest, adjacent shrubbery, wooded patches, and thickets along rivers and streams, especially with bamboo. Loud ringing song is commonly heard, but calling birds can be elusive. At other times can be confiding, walking out at close range as if curious, usually with tail cocked. Plumage distinctive, with bright rusty eyebrow, throat, and breast. Compare with the larger and fatter Chestnut-throated Huet-huet.

Piping Hornbill

Piping Hornbill

Bycanistes fistulator

A medium-sized forest hornbill frequently seen flying overhead or crossing road cuts. Distinctive in its stark pied appearance, with black head, back, forewings, and central tail feathers. In flight, has very distinctive bicolored wings. Similar to African Pied Hornbill, but Piping Hornbill has broad white flight feathers, and its smaller bill and neck give it a stouter appearance. Calls include a rapid series of cackling notes, “huhuhuhuhu,” and higher-pitched piping whistles. 

Scrub Nightjar

Scrub Nightjar

Nyctidromus anthonyi

Brown-and-buff nightbird found in arid scrub and deserts in western Ecuador and northwestern Peru.  It is dark brown, heavily mottled with buff, and has a white throat. In flight, it has white crescents near the wingtips and white stripes along the outer tail feathers. Similar to Common Pauraque, but smaller, with a shorter tail and a different voice. Compared to Tschudi's Nightjar, with which it overlaps in northwestern Peru, Scrub is much darker and has a different song. Scrub Nightjar typically gives a clear, whistled, incessantly repeated “tWEE-oh,” more emphatic and not as burry as Common Pauraque.
