Rufous-bellied Thrush

Small gray swift with a slightly paler rump and belly. Flight is fast but erratic, with the wings pushed forward. Nests in caves, but can be seen in flight over all habitats on the islands of Mauritius and Reunion. The calls include high-pitched twitters and echolocation clicks. Usually easy to identify, as it is the only resident swift on the Mascarenes. Occurs alongside Mascarene Martin, but distinguished by the gray rather than brown overall coloration, unstreaked underparts, and more erratic flight style. 

Beautiful finch-like bird with a small range in the Andes of northwestern Peru. Adult is gray with a chestnut back and wings and a black face and throat. The legs and bill are yellow; the white outer tail feathers are usually only evident in flight. Similar to Great Inca-Finch, but has a smaller black throat patch, a larger mask, and a brighter, less brownish back. Juvenile is washed out and streaky, showing only a hint of the face and throat markings. Inhabits arid areas with dense scrub, and feeds mainly on the ground.

Handsome antwren found in the canopy of lowland rainforest in eastern Ecuador, northeastern Peru, and southern Colombia. Male is gray with black crown, eye-stripe, and upper tail; wings are black with white bars and tail has white edges. Female is similar but with a brown crown and buffy or yellowish wash on breast. Compared to Ancient Antwren, male Dugand’s lacks yellow on underparts, and female has a brown crown. Usually seen with mixed-species flocks very high in the trees. More easily seen from a canopy tower or walkway if one is available. Song is a fast, accelerating series of dry “chup” notes.
