Cream-backed Woodpecker
Campephilus leucopogon
Remarkable large woodpecker, mostly black with a red head and a large cream patch on the back. Females have a cream moustachial stripe and a black forehead. Occurs in open woodlands and savanna. The call is a nasal “pi-ow” and the drum is a double tap.
识别特征
The cream-backed woodpecker is 28 to 30 cm (11 to 12 in) long and weighs 203 to 281 g (7.2 to 9.9 oz). Adult males have a crest; their head, crest, and neck are entirely red but for a small black and white spot on the ear coverts. Adult females have a longer crest than males and do not have the covert spot. They have a creamy band from the bill to the ear coverts with black above it that surrounds the eye and extends along the front of the crest, and also a thinner black line below the creamy band. The rest of their head is red and their neck is black. Adults of both sexes are mostly black below the neck. They have a whitish upper back with pale cinnamon-buff feather tips and sometimes a few buff and black barred feathers in the center of the back. Their flight feathers have much pale cinnamon on the bases of their inner webs. Their bill is a long ivory chisel, their iris pale yellow, and their legs gray. Juveniles resemble adults but with less red that is more orange. Males resemble adult females with a red crown and crest and females have less red on their head than adults.

It inhabits the generally open landscapes of the dry Gran Chaco including savanna, woodlands, transitional forest, pastures with copses of trees, and palm groves. In elevation it ranges up to 2,500 m (8,200 ft).

行为
The cream-backed woodpecker is a year-round resident throughout its range.<p>The cream-backed woodpecker's primary food is beetle larvae. It mostly forages in tall trees, often those isolated in otherwise open areas, but will feed on fallen logs. It exposes its prey by hammering and less frequently by pecking and probing. It mostly forages alone except in the breeding season.<p>The cream-backed woodpecker's breeding season begins in September but is concentrated in October and November. It excavates a nest hole in a tree or palm; the few known ones have been 6 to 8 m (20 to 25 ft) above the ground. Both parents feed nestlings, but other details of parental care, the clutch size, incubation period, and time to fledging are not known.<p>The cream-backed woodpecker's call is "pi-ow" or "kwee-yaw" that is sometimes repeated. Partners exchange "whirring notes". It also communicates with a quiet "ahem" and various soft and squeaky chattering calls. Its drum is a double tap.

Yellow-rumped Serin
Crithagra xanthopygia
A very plain gray-brown seedeater with a white throat and a yellow rump that is conspicuous in flight. Found locally in savanna, woodland, and cultivated areas, usually in small flocks. Similar to Reichenow’s Seedeater, but has a weaker facial pattern and usually less streaking below. Separated from White-rumped Seedeater by the yellow rump and the whiter throat. Also similar to Yellow-throated and Salvadori’s Serins, but separated by the white rather than yellow throat. The song is a constant stream of musical whistles and trills.
Hume's Treecreeper
Certhia manipurensis
Physically almost identical to Sikkim Treecreeper, but throat pale tan-orange instead gray. Bright contrasting rusty tail distinguishes it from other treecreepers in its range. A species of foothill to montane and submontane regions; averages lower in elevational range than Sikkim Treecreeper, with minimal to no range overlap. Favors broadleaf evergreen and mixed forests. Occasionally found in mixed-species flocks. Song is slower than that of Sikkim Treecreeper, a rather slow ringing trill composed of paired notes; calls include an echoing two-note “tsijew” and a high “tzit.”
Black-backed Dwarf-Kingfisher
Ceyx erithaca
A brilliantly colored, tiny forest kingfisher with a coral-red dagger bill. It has a dark blue back and wings and pale orange underparts. Crown is fuschia-red, with a dark spot on the forehead and blue and white patches on the side of the neck. Chin and throat are white. Found along drying hill streams, and often away from water sources. Flight is swift and direct, as the bird expertly maneuvers through thick vegetation. Gives piercing high, thin calls, often when in flight.
