Mistletoe Tyrannulet
Zimmerius parvus
Small, drab tyrannulet found in the lowlands from eastern Guatemala and Belize south to extreme northwestern Colombia. Fairly inconspicuous; usually found as singles or pairs in middle to upper levels of forests, plantations, and second-growth. Typically perches fairly horizontally with the tail held slightly cocked. Feeds mainly on berries. Note the dull whitish eyebrow, small bill, and bright yellow edging on wing feathers.
识别特征
The mistletoe tyrannulet is a small bird, 11 – 12 cm in length as an adult. Adults have a slaty cap, a bright white supercilium ("eyebrow"), an olive-green back and conspicuous yellow edging along the wing.
分类信息
The mistletoe tyrannulet was described in 1862 by the American amateur ornithologist George Newbold Lawrence under the binomial name Tyranniscus parvus. It was formerly considered to be conspecific with the Guatemalan tyrannulet (Zimmerius vilissimus), but the species were split based on a molecular phylogenetic study published in 2013.

分布与栖息地
The mistletoe tyrannulet ranges from Guatemala and Honduras south to the extremity of northwestern Colombia. It can be found in humid evergreen forest and edge, cultivation and semi-open areas with large trees. It is a fairly common to common bird across its range.<p>This species is a very frequent caller, incessantly giving a call that has been rendered variously as peeyaik, pee-peeu or pee-yuip and sounds similar to that of the thick-billed euphonia (Euphonia laniirostris), another mistletoe-loving species.

行为
The mistletoe tyrannulet's nest is a globular mass of rootlets, mosses and other plant matter, hidden in a tangle or growth or in an epiphyte. The clutch is two whitish eggs, speckled rusty.<p>The mistletoe tyrannulet is an active forager, moving quickly about with its tail cocked as it searches for prey, mainly arthropods, amidst the foliage. It can be found as a member of a mixed-species feeding flock. The bird also takes fruit, preferentially that of mistletoes (order Santalales).

Baird's Trogon
Trogon bairdii
Unique trogon with dark purplish head and breast, turquoise back, white undertail, and pale blue bill and eyering. No white band between chest and belly. Female mostly gray with red belly, perhaps most similar to Slaty-tailed Trogon but note pale blue eyering, gray bill, and thin white bars on undertail. Limited range. Look for a bird sitting upright and still at middle levels in the forest, slowly turning head searching for prey. Usually single or in pairs. Song is a fairly fast, accelerating series of cluck notes.
Usambara Weaver
Ploceus nicolli
An unusual weaver with dark upperparts, an orange bib, and a yellow belly. The male shows a yellowish forehead patch that the female lacks. Found very locally in the upper levels of montane forest, usually in pairs that often join mixed-species flocks. Creeps along branches like a nuthatch. Somewhat similar to Forest Weaver, but easily separated by the orange breast. Vocalizations include a “seet-swit” call that is unusual for a weaver and a “radio static” song with a distinctively rollicking rhythm.
Blue-backed Conebill
Conirostrum sitticolor
Small attractive tanager, fairly common and widespread in the temperate zone of the Andes from Venezuela to Bolivia. Black head, blue back, black wings, and burnt-orange belly. Sexes alike. Where it overlaps with Chestnut-bellied Mountain-Tanager note the conebills smaller size and more pointed bill. Typically found in pairs or small family groups working the middle and upper levels of temperate forest and edge. Often follows mixed-species flocks.
