Red-billed Tyrannulet

Plump bird with long legs and a short tail that ranges in the eastern Andes of Colombia, barely reaching over the border into Venezuela. Plumage is chestnut brown with an orange tinge to the breast and slightly paler belly; sometimes shows a faint mustache streak. Skulks in the understory of high elevation elfin forest and usually stays on the ground, but sometimes comes up to a low perch to sing. Common vocalization is a sweet, rising whistle followed by a lower pitched gargle, and also gives a series of flat whistles. It used to be called Rufous Antpitta.

Fairly dull vireo, intermediate between Blue-headed and Plumbeous. Grayish-olive overall, but with yellowish flanks and greenish back. Note white spectacles contrasting with gray head and two whitish wingbars. Breeds in mixed coniferous forests, especially in mountainous areas; winters in Mexico. Often separable from Blue-headed and Plumbeous Vireos by range, but can overlap during migration and winter. Cassin's is less contrasty than Blue-headed, especially between the gray face and whitish throat, and the greenish back blends into the nape and crown. Some birds are best left unidentified.

Small and stout forest-dweller that hops and buzzes about in the canopy like a large, active insect. Note male’s iridescent dark blue back, red chest patch, and black line extending partway down the white belly. As with many other flowerpeckers, the female is considerably duller, with a red rump patch being the only patch of bright color on her otherwise gray-brown plumage. Endemic to Timor, where found in montane and foothill forests. Song is a brief, high-pitched and silvery burst of whistled notes: “tsee’di-lee’see.”
