A graceful aerial feeder found over a wide variety of open habitats, especially near water, including marshes and towns. Often seen on exposed perches including power and telephone lines in villages. Commonly found in flocks of up to twenty birds, sometimes mixing with other swallows and martins. Note the male’s diagnostic glossy purple-blue plumage and snow-white belly. Females and immatures are similarly patterned, but have brown mixed with the blue and are probably not safely separable from Cuban Martin. Female and immature Purple Martins are very similar, but they often have a scaly breast and finely streaked belly, with less contrast between belly and chest. Notably, Cuban and Purple Martins are not present in this species’ range from March to September. Calls include a harsh “churr,” a buzzy “zwick-zwick,” and a musical buzzy burbling.

Widespread, rather large but “average” coot of lakes, marshes, and river mouths; mainly in Andes and adjacent Pacific coastal lowlands. Despite the name, its plumage is no more slate-colored than other coots. Adult comes in three types: most Andean birds have a dark red forehead shield and yellowish bill; elsewhere, rounded forehead shield can be white or pale yellow with a whitish bill. Legs greenish, appreciably shorter than legs of Giant Coot, which occurs alongside Slate-colored at some lakes. Juvenile has a variably grizzled whitish face and throat.

Brownish bunting with boldly striped black-and-white head, bright chestnut wings and buffy wash on the breast that fades towards the vent. Endemic to Socotra, where it prefers rocky areas in shrubland and grassland. Typically encountered hopping on the ground searching for food. Pairs breed between 600–1200m, but move to the coastal plain after breeding, where they form small flocks. Song is typically a series of three or four short strident notes, “tseet-tee-too” or “steet-tsoo-steet-tsoo.”
