Opal-crowned Manakin

A large, long-billed bird of lowland forest. Brown upperparts with black head and grayish facial skin behind the eye. Note the curved, pale bill. Male has a black throat, sides and two small, hornlike tufts on the head. Female has pale underparts with dark barring. Similar to female Twelve-wired Bird-of-Paradise and Magnificent Riflebird, but female Pale-billed Sicklebill has a longer, thinner, more curved bill. One of several vocalizations, a descending series of low whistles, reminiscent of Common Potoo.

The largest nuthatch in the world, about the size of a bulbul. Coloration similar to many other nuthatches: gray above and white below, with a thick black line through the eye. Picky in its habitat preferences and as a result generally uncommon or absent through much of its range; requires extensive stands of mature tall pines in foothills and montane regions. Can be quite loud, giving a hoarse chatter reminiscent of a corvid; also gives a clipped fluty whistle.

Unmistakable ground dove. Brownish above and whitish below. Note the black spotting on the wings and the yellow eye-ring and legs. In flight the tail is V-shaped, with black sides and white tips. Found in grasslands and at the woodland edge, where it feeds on the ground. The song is a series of high-pitched “wha-ooop...wha-ooop...wha-ooop...” notes.
