Black Heron
Egretta ardesiaca
Chunky, mid-sized, blackish heron. The bill and legs are black and the feet are yellow. Found mainly in freshwater and brackish wetlands, though occasionally on saltwater. Famous for its “umbrella” feeding technique in which it hunts for food inside of its own spread and curled wings. Similar to the dark morph of other egret species, but smaller, shorter-necked, and without a pale patch at the base of the bill.

Note more extensive crown spotting on Olive-backed. Otherwise distinctive in range. Like other woodcreepers, usually seen singly or in pairs, often accompanying a mixed-species flock. Hitches up tree trunks and large limbs. Typically found within forest or adjacent edges or second growth.
