Streak-headed Woodcreeper
Lepidocolaptes souleyetii
Medium-size, fairly common woodcreeper of tropical lowlands. Favors forest edge, open woodland, hedges with tall trees. Feeds on trunks and larger branches, often spiraling up one trunk and flying low to the next tree. Note the relatively slender and slightly decurved bill, distinct but fine pale streaking on the head and back. Easily confused with larger Ivory-billed Woodcreeper, which is more of a forest bird and has a bigger and straighter bill.
识别特征
The streak-headed woodcreeper is 19 to 21 cm (7.5 to 8.3 in) long and weighs 23 to 31 g (0.81 to 1.1 oz). It is a slim, medium-sized woodcreeper with a longish, slender, decurved bill. The sexes have the same plumage. Adults of the nominate subspecies L. s. souleyetii have a face with thin whitish buff and dark brown streaks; the sides of the neck are more heavily streaked. They have a whitish buff supercilium and eyering. Their crown and nape are dark brown with bold whitish buff streaks that often extend onto the upper back. Their back and wing coverts are rufous-olive to cinnamon-brown. Their flight feathers, rump, and tail are cinnamon-rufous to rufous-chestnut. Their primaries have brownish edges and dusky tips. Their throat is whitish buff to pale cinnamon. Their underparts are grayish olive to buffy brown with black-edged whitish buff streaks. The streaks are wide on the breast and sides, those on the belly and flanks narrower, and those on the undertail coverts minimal. Their underwing coverts are ochraceous to pale cinnamon-buff. Their iris is pale brown or brown, their bill pale brown or horn with most of the mandible bluish-pink, and their legs and feet grayish olive-green. Juveniles are very similar to adults but with small scattered dusky spots instead of streaks on their underparts.<p>The other subspecies of the streak-headed woodcreeper differ from the nominate and each other thus:

分布与栖息地
The subspecies of the streak-headed woodcreeper are found thus:<p>The streak-headed woodcreeper inhabits a variety of wooded landscapes, most of them semi-open to open. These include deciduous and somewhat humid forest, gallery forest, secondary forest, plantations, the edges of humid forest, and open areas with scattered trees. It also locally occurs in mangrove and in arid scrublands. In elevation it reaches 1,500 m (4,900 ft) in Mexico, 1,850 m (6,100 ft) in northern Central America, 1,500 m (4,900 ft) in Costa Rica (though uncommon above 900 m (3,000 ft)), 1,500 m (4,900 ft) in Colombia, and 1,600 m (5,200 ft) in Venezuela. In Ecuador it mostly occurs below 800 m (2,600 ft) but reaches 1,800 m (5,900 ft) locally in Loja Province.

Red-billed Pigeon
Patagioenas flavirostris
Large dark pigeon. Body and wings mostly bluish-gray with maroon-colored neck and shoulders. Note red bill with pale yellowish tip. Immature paler grayish without maroon tones. Common from Mexico to Costa Rica, mainly in lowlands and foothills. Barely enters the U.S. in Rio Grande Valley of south Texas. Typically seen in pairs or small flocks, often perched conspicuously in a variety of habitats, including open forests, patchy farmland, and mangroves. Tends to be fairly shy. Separated from other pigeons in Middle America by large size, bill pattern, and dark tail and undertail coverts. Listen for low cooing song: “whoo, whoop-a-whoo.”
Green-striped Brushfinch
Arremon virenticeps
Fairly stocky, sparrowlike bird endemic to highland forests. Occurs mainly in fir and humid pine-oak forest understory, often in brushy flower banks and shady canyons, where typically skulking and difficult to see well. Feeds on and near the ground, usually in pairs. White throat stands out in shady understory, but green head stripes can be difficult to see. Range does not overlap rather similar Chestnut-capped Brushfinch.
White-crowned Lapwing
Vanellus albiceps
This striking lapwing is best identified by its long yellow wattles, white belly, and gray head split down the center by a broad white crown stripe. In flight, the distinctive wings are almost entirely white with black tips. It prefers breeding and foraging on large permanent rivers with extensive sand banks but will also wander to smaller streams and pans. It utters a loud “kriiip” call when alarmed or defending its territory. The similar Wattled Lapwing differs from White-headed Lapwing by having a dark belly and red-based wattles.
