Small-headed Elaenia

Medium-sized, active flycatcher of forest canopy; often observed on the periphery of mixed-species flocks. When seen well, note entirely yellow underparts, including throat. Found in a variety of lowland forest types, including tall rainforest and low-stature forests on sandy soils. Forages actively, almost always in small groups; often sits on top of large leaf clusters on outer branches. Similar to several other kiskadee-like flycatchers, but behavior and voice are quite different. Quite vocal; often-heard call is a distinctive hollow rattle with a purring quality.

A large, mostly black-and-white hornbill that occurs in thickets, dense woodland, and riverine and coastal forest. It can be surprisingly inconspicuous while eating large fruit in forest trees, but in flight it has noisy wingbeats and a far-carrying baby-like wailing “whaaaaaa waa waa” call. In flight note narrow white hind edges to the mostly dark wings; the similar Black-and-white-casqued Hornbill has a very broad white hind edge, and the Silvery-cheeked Hornbill has no white hind edge.

A small and difficult to identify woodcreeper, widespread but often rare and seldom encountered. Smaller than most other woodcreeper species in range (slightly larger than Olivaceous Woodcreeper), with a relatively short, straight bill and weakly marked brown plumage. Note the faint pale streaking on the head and spots on the throat. Best found and identified by voice, a fast, even trill lasting between 1-2 seconds and usually heard at dawn.
