Schlegel's Francolin

An elegant aerial hunter most often found in pine woodlands, but also seen in towns and over fields. Note the long forked tail, green to blue-green upperparts, and white underparts. Tree Swallows are similarly colored, but have a shorter, notched tail. Tree Swallows also have entirely dusky underwings unlike Bahama Swallows which have white armpits. Calls include a slightly squeaky “chet” or “chet-chet” and a thin “tsi-tsip.” Song is a beautiful liquid jumble of rich notes.

An entirely black crow with a fairly thick, raven-like bill. Found in a variety of dry country habitats, including savanna, thornscrub, desert, towns, and cultivated areas. Often in small flocks. Similar to Fan-tailed Raven, but has a different shape, especially in flight, with a much longer tail. Very similar to Brown-necked Raven, but smaller, and there is little overlap in range. Typical birds look very different from Pied Crow, but these two species sometimes hybridize, producing birds with white blotching on the back and underparts. The calls are typical rough cawing notes. 

Uncommon in the Andes from western Venezuela to Argentina. Male is black above with a yellow belly and prominent white patches on the wings. Most populations have an entirely black head and chest, but birds in southern Colombia and Ecuador have yellow up the throat. Females are similar to males, but are duller brownish instead of black with more yellowish mottling above. Both sexes have huge bill. Occurs in scrubby woodlands, forest edge, and gardens from around 500 to 3,200 m. Often found in pairs that perch conspicuously.
