Mangrove Pitta
Pitta megarhyncha
The huge crab-smashing bill of this mangrove specialist sets it apart from all other pittas. Brightly colored with a black mask, green-and-black wings, and a yellow belly. Similar in color to Blue-winged Pitta, but note Mangrove’s larger-headed appearance and habitat. Like other pittas, shy and difficult to see; listen for its throaty and fluid two-parted whistles.
识别特征
Measuring 180 to 210 mm (7.1–8.3 in) in length, the mangrove pitta has a black head with a buff-coloured crown, white chin and buff underparts. The shoulders and mantle are greenish and the vent is reddish. Juveniles have similar patterned plumage but are duller. It resembles the blue-winged pitta but can be distinguished by its much heavier bill. Its call, transcribed as wieuw-wieuw has been noted to be "more slurred" than the blue-winged pitta.
分类信息
The mangrove pitta was first described by German ornithologist Hermann Schlegel in 1863. Its species name is derived from the Ancient Greek words mega- "large", and rhynchos "beak". It forms a superspecies with the Indian pitta (P. brachyura), fairy pitta (P. nympha) and blue-winged pitta (P. moluccensis). Alternate common names include: Larger blue-winged/Malay pitta, Brève des palétuviers (in French), Große Blauflügelpitta (in German), and Pita de Manglar (in Spanish). There are no recognized subspecies.

行为
While all pittas are noted for being difficult to study and spot in the wild, the mangrove pitta is one of the easier ones to spot as it sits high up in mangrove trees and calls. A tape recording of its call will often bring it forth. It tends to be vocal while brooding but quiet at other times.

Bennett's Woodpecker
Campethera bennettii
A medium-sized woodpecker with spotted rather than streaked or barred underparts. The male has unmarked white cheeks and throat, and red moustachial streaks and crown, while the female has a distinctive brown throat, cheek, and eye-stripes. Pairs and small groups avoid drier scrub, preferring mature broadleaved woodland, foraging for ants, termites and their larvae, mostly on the ground. The similar Reichenow’s Woodpecker differs from Bennett’s Woodpecker by being smaller, having a diagnostic speckled throat and less bold facial pattern.
Blue-cheeked Amazon
Amazona dufresniana
Generally uncommon parrot of lowland rainforest; also found in premontane forest at higher elevations in the tepui region and locally in savanna forest. Ecology and behavior similar to others in the genus. Note voice and burnt-orange forehead; diagnostic blue cheeks can be difficult to see. Feeds on fruit and flowers in the canopy; often seen commuting to or from roosts, or between feeding areas. Vocalizations are varied; most common call is a repeated yelp, similar to Orange-winged Parrot but somewhat lower-pitched and with a more liquid quality.
Buff-spotted Woodpecker
Pardipicus nivosus
A small, relatively dark woodpecker of humid forest. Mostly dark olive-green with a paler face and underparts. The throat is streaked, the breast is spotted, and the belly is barred. Males have a small red patch on the back of the head. Found in rainforest and thick secondary forest at low and middle elevations. Spends most of its time at middle levels and in the understory. Similar to Brown-eared Woodpecker, but smaller, without a dark cheek patch. Also reminiscent of Green-backed and Little Green Woodpeckers, but separated by the spotted rather than barred breast. Not very vocal, but does give a descending, mournful whistle.
