El Oro Parakeet

A very small nondescript sunbird with a short orange-based bill that curves uniformly along its length; easily mistaken for females of other sunbirds. The only features on the olive upperparts are indistinct paler eyebrows and lines running under the eyes, and yellow edging to the wings. Although often hidden, the male has yellow or whitish (not red) tufts at the shoulders. Singles are local and inconspicuous at the edges of lowland and riverine forest, sometimes entering secondary growth; it joins mixed-flocks and is frequently attracted to epiphytes in mossy clumps. Calls a high-pitched “tseeep” and trills. Little Green and Fraser’s sunbirds are similar to Bates’s but brighter, with straighter bills and more distinct yellowish eye-rings; Ursula’s Sunbird has a long decurved bill and grayish face and underparts.

Attractive black-and-yellow oriole. Mainly in pine-oak forest of highlands, but also in humid tropical lowlands of Yucatan Peninsula. Often in flowering trees with other species of orioles. Both sexes have a yellow head and body with a small black mask and throat patch, black wings and tail. Bill is straight and pointed. Richly whistled and slightly halting song carries well.

Small flycatcher with brilliant blue upperparts, a pale orange throat and chest, and a white belly. Slightly paler female has a whitish throat, while male’s is blue; sexes are otherwise quite similar. Head is fairly uniformly blue, without boldly lighter or darker patches, unlike in many other “blue flycatchers”. Pale and restricted orange also serves as a helpful identifying feature. A lowland species, restricted to secluded riverine forests in Sumatra and the Malay Peninsula, but found in a variety of dry and wet forests on Borneo. Song is a short smooth series of drawn-out piping whistles.
