Barred Puffbird
Nystalus radiatus
An unobtrusive bird with an oversized head and bill. Look for tiger-striped pattern—warm cinnamon-brown overall with uneven black barring. Also note slightly darker cap and staring pale eye. Uncommon; found around forest edge and secondary woodland in the lowlands from Panama to western Ecuador. Perches still for long periods of time, often on an exposed perch. Frequently detected by distinctive wolf-whistling calls.
识别特征
The barred puffbird is about 22 cm (8.7 in) long and weighs about 63 g (2.2 oz). Its crown is blackish with dark rufous bars. The upper nape is black, the lower nape yellowish red, and the upper mantle black. The rest of the upperparts and the wings are dark chestnut with narrow black bands. The tail is long, narrow, and chestnut with narrow black bands. The chin is whitish. The face and underparts are pale rufous with fine blackish bars except in the center of the belly. The bill is grayish yellow to blackish, the eye creamy yellow, and the feet greenish gray. The "fulvidus" morph is a deeper rufous overall.
分类信息
In the first half of the twentieth century the barred puffbird was treated by some authors as belonging to genus Ecchaunornis, but since then was returned to genus Nystalus. It is monotypic. A proposed subspecies, "N. r. fulvidus" is probably a color morph.

分布与栖息地
The barred puffbird is resident from central Panama into northern Colombia and through western Colombia into western Ecuador. It inhabits the lower levels of several semi-open landscapes including the borders of humid and wet forest, streamside vegetation, clearings with scattered trees, and the edges of forest trails. In Ecuador it has regularly been recorded perched on wires in agricultural areas. In elevation it is usually found up to 900 m (3,000 ft) but has been recorded locally in the Mindo, Ecuador region as high as 1,675 m (5,500 ft) and once at 1,550 m (5,100 ft) in Colombia.

行为
The barred puffbird's foraging behavior has not been documented; other puffbirds typically hunt by sallying from a perch. Its diet includes large insects of several orders and small lizards.<p>The only described nest of a barred puffbird was a cup of dead leaves. It was in a spherical chamber at the end of a narrow tunnel excavated in a clay bank and partially shaded by vegetation. It contained two well-grown nestlings.<p>The barred puffbird's song is "a long, slow, ventriloquial and very human-like wolf-whistle, 'phweeeeeet-weeeeeeuuuu'". Near the nest it made low-pitched "werr" and "werr werr woo" calls.

Cobalt-winged Parakeet
Brotogeris cyanoptera
Small green parakeet with a short tail. Blue wing feathers are hard to see when perched but are conspicuous in flight. Found in a variety of forested habitats, including around forest edges, gardens, and agricultural areas, often traveling in loud groups. Distinguished from similar Tui Parakeet by dark eye, green forehead, and peach chin, and from parrotlets by its larger size.
Masked Fruiteater
Pipreola pulchra
Chunky green bird with a broad, blunt bill. Males have a bright orange bill, a blackish face, a yellow-orange necklace that bleeds into the breast, and a yellow lower belly; females are nearly entirely green with faint streaking below and a dull orange bill. Notice the females’ dull olive legs and streaked, not scaled pattern underneath, which distinguish it from the similar, orange-legged female Scarlet-breasted Fruiteater. Perches inconspicuously in the mid-story of humid montane forest, where it is often found around fruiting trees and occasionally joins mixed-species flocks.
Marico Sunbird
Cinnyris mariquensis
Male is iridescent green above with a dark belly and maroon and bluish bands across the breast. Female is nondescript, with blurry streaks across the pale yellow underparts. Found in woodland, scrub, and savanna, including semi-desert thornscrub. Most distinctive vocalization is an energetic series of “tyip” notes. Also gives a high-pitched, jumbled song. Very similar to several other sunbird species but distinguished by slightly larger size and longer bill with a thicker base.
