Turati's Boubou

Turati's Boubou

Laniarius turatii

Chunky black-and-white bushshrike. The upperparts are cleanly black and the underparts are white with a pinkish wash, especially on the breast. Uses habitats with a dense understory, including riparian thickets within savanna, as well as forest edge. Usually found in pairs. Similar to Tropical Boubou, but there is little overlap in range, and Turati’s is separated by the lack of a white shoulder patch. The typical vocalization is a duet in which the male gives a hollow, rising whistle and the female a low, rasping, frog-like note. 

Chestnut-rumped Heathwren

Chestnut-rumped Heathwren

Hylacola pyrrhopygia

Small bird of dense heath and shrubland in southeastern Australia. Pale brown above, whitish below, with distinct pale supercilium, red-brown rump, small white patch at the base of primaries, fine dark chest streaking, and long, cocked tail. Forages quietly on the ground or in thick vegetation, where difficult to see. Compare Shy Heathwren, which has a white wing spot, more black in wing, and darker legs.

Black-throated Blue Warbler

Black-throated Blue Warbler

Setophaga caerulescens

Striking warbler with vastly different male and female plumages. Males are unique deep blue above with black face and sides and white belly. Females are plain brownish-olive with dingy buffy underparts and subtle face pattern. Always look for small white patch on the wing, lacking only on the dullest immature females. Breeds in the understory of mixed forests, favoring hills with dense vegetation. Found in nearly any wooded or shrubby habitat during migration. Winters primarily in the Caribbean. Listen for lazy buzzy song, usually a series of notes with a final long buzz.
