Brown Parrotbill

Medium to large woodcreeper of humid evergreen and pine-evergreen forest in highlands and foothills. Feeds at all levels on trunks and larger branches, often at bromeliads. Straightish and rather stout bill is dark above and pale below. Note the pale buff spectacles and distinct pale spotting and scalloping on head, breast, and back (populations south of western Honduras lack spotting on back.)

A large, unusual bushshrike of Tanzania’s Uluguru Mountains with a huge bill, a black head, a green back, and yellow underparts. Found in the canopy of montane forest, usually in pairs. Most often detected by the distinctive and unusual voice, which consists of sliding whistles given in pairs, one lower and one higher, along with well-spaced ratcheting notes. These two vocalizations are usually synchronized as a duet by a pair. 

A small, distinctively proportioned shearwater with a comparatively long-necked, long-tailed, round-winged appearance. Entirely dark plumage contrasts with variably white bars on the underside of remarkably short, stubby wings. Long thin bill is often obvious, as is this species’ habit of flying with its head raised above its body. Pale morph is paler below and overall lighter brown, but retains odd proportions. The dark morph of Wedge-tailed Shearwater is somewhat similar, but much larger and longer-tailed. Black Noddy is similar in size, but has a more buoyant, bouncy tern-like flight. Christmas Shearwater is most similar, but has a proportionally shorter bill and tail. Short-tailed and Sooty Shearwaters are similar in plumage, but their toes project beyond their tail, unlike in Heinroth’s Shearwater.
