Caatinga Black-Tyrant

A slim, long-tailed all-black flycatcher with a dark eye. Found in savanna, woodland, and cultivated areas. Single birds or pairs sit out on conspicuous perches, sometimes quite low. Very similar to Southern Black-Flycatcher, but there is virtually no overlap in range, and Northern lacks gloss in the black plumage. Distinguished from drongos by the slimmer bill and dark brown eye. Could be confused with certain black cuckooshrikes or boubous, but has a more vertical posture, and sits motionless for much longer periods. Not very vocal, but does have a pretty song of various trills, wheezes, and whistles given with long pauses between phrases. 

A shy but loud bird of forests and forest edges that usually stays within cover. Shaped like a greenbul, but has a thicker, more robust bill. Shows grayish underparts, greenish upperparts, yellow spots on the tips of the flight feathers and upperwing coverts, a yellow throat, and yellow lores. Similar to the larger Western Nicator, but note Yellow-throated’s smaller size, yellow throat and lores, and distinctive song, which often betrays its presence: a sputtering series of notes that can be surprisingly resonant and loud, a “p-p-p-po-keer-ko-wheeeer-pop” and other variations. Call is a growling trill, “prrrrrr.” 

A gregarious species of open habitats, especially weedy and agricultural areas; occurs in flocks of tens to hundreds. Typically one of the most common weaver species where it occurs, but care should be taken to separate it from rarer species, especially when in nonbreeding plumage. Note the red eyes, hefty bill, and relatively large size. Where introduced in the Caribbean, the bill shape and eye color separate breeding male weavers from oriole species. Village Weavers in other plumages are distinguished from the Northern Red Bishop by their larger size, larger bill, and eye color. Constructs compact hanging woven nests, often in large colonies in or near towns. Like most weavers, has a remarkable song made up of a jumble of squeaky notes followed by a drawn out sizzling buzz. Calls include a sharp “dzip” and “chut” or “chit” given singly or in series. Flocks create a loud burbling chatter.
