Fasciated Wren
Campylorhynchus fasciatus
Large, noisy wren of dry and semi-humid areas; ranges from western Ecuador south to central Peru. Upperparts, sides, and tail are boldly barred with gray and white, and breast is spotted with gray. Similar to Band-backed Wren, but lacks chestnut on underparts, has paler breast spots, and prefers more arid habitats. Pairs or small groups forage conspicuously in bushes and trees, giving a variety of harsh, raspy calls.

分布与栖息地
The nominate fasciated wren is found in coastal Peru from the Department of Piura south to the Department of Lima and also inland Peru from the departments of Cajamarca and Amazonas south to the Department of Huánuco. C. f. pallescens is found from southwestern and southern Ecuador into Peru's departments of Tumbes and Piura.<p>The fasciated wren primarily inhabits arid and semi-arid landscapes such as thorny scrublands. It also occurs in citrus orchards and other areas that humans have heavily modified. In Ecuador it uses more humid habitat including deciduous forest. In elevation the species is usually found between sea level and 1,500 m (4,900 ft) but can be found as high as 2,500 m (8,200 ft).

行为
The fasciated wren's diet is principally invertebrates but also includes some vegetable matter. It forages in groups, mostly in bushes and shrubs but sometimes on the ground.<p>The fasciated wren's breeding season extends from May to August in most areas, but active nests have been noted in February and March in Ecuador. The species is a cooperative breeder, with groups of up to 10 individuals including a dominant pair. Its nest is a dome with a side entrance, constructed of grass and lined with feathers. It is sited in several species of trees and cactus. It also frequently uses an old mud nest of the pale-legged hornero (Furnarius leucopus).<p>The fasciated wren is a duet or group singer. Its song is "a series of harsh churring notes interspersed with gurgling notes" [1]. Its call is "a harsh 'churr'" [2].

其他鸟类
Ash-throated Casiornis
Casiornis fuscus
Large rufous flycatcher with a slight crest, a cinnamon back, dusky flight feathers, and buff underparts. Inhabits wooded caatinga (dry scrubby forest) in the breeding season, with migrants also found in Cerrado and Amazonian savannas and light woodland in the non-breeding season. The similar Rufous Casiornis has a rufous back, the same color as the wings.
African Jacana
Actophilornis africanus
A distinctive chestnut, white, and black waterbird with a sky-blue bill and enormous feet. The immature lacks the blue bill and shield and is brown-headed. Resident and nomadic, this species trots on the surface of water lilies and other aquatic vegetation, using its long legs and ludicrously elongated toes to prevent it from sinking. It flies weakly, low over the water, with legs and toes dangling behind awkwardly, and calls with a honking repeated “kyaaan” and wheezy hurried “skreeeeeet’--most often in flight. Highly unusual mating system in which one dominant female maintains a harem of multiple males. After egg-laying, each male will raise a brood alone.
Greater Yellow-headed Vulture
Cathartes melambrotus
Widespread and common vulture in lowland rainforest. Head may not appear yellow unless seen at close range. Best identified by steady flight with wings held at a slight dihedral. Similar to Turkey Vulture, but has broader wings which it holds flatter and does not teeter from side to side as often. Occurs in rainforest, cities, and agricultural areas.
