Purple-winged Roller
Coracias temminckii
A distinctive big-billed bird that is entirely deep purple in color except for a conspicuous sky-blue cap and rump. Juvenile has a duller cap and browner underparts. Sits upright. Prefers open country near wooded and forested areas, where it is most often seen perched high on prominent dead branches, usually singly or in pairs. Occurs in both lowlands and foothills. Gives a harsh, dry grating call, “ka-ka-ka-ka…”, and sometimes also a single “chowwEER.”
Identification
The purple-winged roller is 30–34 cm (12–13 in) in length, similar in size to the Eurasian jay. The cap and upper-tail coverts are bright azure blue, the back is dark-olive, with the rest of the plumage mainly dark blue. The large bill is black. The sexes are alike. Juveniles are similar to the adults but with duller plumage.
Taxonomy
The purple-winged roller was formally described in 1819 by the French ornithologist Louis Pierre Vieillot under the binomial name Garrulus temminckii. The specific epithet was chosen to honour the Dutch ornithologist Coenraad Jacob Temminck. The type locality is the island of Sulawesi. The purple-winged roller is now one of nine species placed in the genus Coracias that was introduced by Carl Linnaeus in 1758. A molecular phylogenetic study published in 2018 found that the purple-winged roller was most closely related to the Indochinese roller (Coracias affinis).<p>The phylogenetic relationships among the Coracias species are shown below, from the molecular study by Johansson et al. (2018)<p>Alternate names for the purple-winged roller include the Celebes roller, Sulawesi roller, and Temminck's roller.

Hardhead
Aythya australis
Chocolate brown diving duck with white rump and large white panels in the wings. Male has white eyes. Female is slightly paler with dusky eyes. Similar to Musk and Blue-billed Ducks, but Hardhead sits higher in the water, has a white patch on the rump, and lacks a spiky tail.
Red-capped Manakin
Ceratopipra mentalis
Chunky little bird of middle levels and understory in humid tropical forest of lowlands. Away from display areas, usually found in ones and twos perched quietly or feeding at fruiting trees and bushes from understory to canopy. Often sits still for long periods and easily overlooked. Male unmistakable: flame-red head glows in shady forest. Female notably drab, dull greenish with dull pinkish bill, dark legs, best identified by shape and behavior.
Desert Finch
Rhodospiza obsoleta
This subtly handsome finch is unique in its range; warm sandy brown with bright pink and silver flashes in the wings. Sexes are similar, but the male boasts a restricted black mask extending from the front of the eye to the base of the stout charcoal-black bill, which the female lacks. Not restricted to deserts but generally does prefer dry, open areas in middle to high altitude regions. Frequents villages, towns, and even cities. Gives a tumbling series of random-sounding notes, usually with a rather hoarse, buzzy quality. Calls include “chip” and “chink” notes and buzzy wheezes.
