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.
Identification
The fasciated wren is approximately 19 cm (7.5 in) long; one female weighed 24.9 g (0.88 oz). Both sexes of the nominate have a gray crown, grayish supercilium, and dark gray shoulders, back, and rump. The shoulders have whitish speckles and the rump whitish bars. The tail is barred off-white and blackish brown. The chin is off-white with darker streaks. The whitish chest and belly have heavy dark gray spots and the flanks are barred with dark gray. C. f. pallescens is paler with less distinct markings on the underside. The juvenile also has less well defined markings on its underside.
Taxonomy
The fasciated wren has two subspecies, the nominate Campylorhynchus fasciatus fasciatus and C. f. pallescens.

Range and habitat
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).

Behavior
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].

Scarlet-backed Flowerpecker
Dicaeum cruentatum
One of many flowerpeckers in which the male is brightly-colored and the female is predominantly brown. Adult male is black and white from below, but above it is bright red from the crown down to the rump. The female, while largely dull, can be distinguished from other flowerpeckers by her bright red rump that is often visible when hovering and foraging. Juvenile lacks the red rump, but has a white throat and is a much darker brown above than the similar Plain Flowerpecker. A lowland species, often found in gardens with flowering and fruiting plants, particularly mistletoe. Often detected through its metallic ticking calls.
Mountain Wagtail
Motacilla clara
Elegant, long-tailed bird with a gray back, pale underparts, and a black chest band. White outer tail is conspicuous in flight. Found along streams, mainly within montane forest. Feeds by walking along the ground, bobbing its tail constantly. Call is a buzzy “tseeet”. Song is a complex and beautiful jumble of high notes and trills. Similar to Cape Wagtail but has gray rather than brown upperparts and has more white in the wings and tail. Also similar to Gray Wagtail but lacks yellow on the underparts.
Congo Martin
Riparia congica
A typical small martin with brown upperparts, pale underparts, and a diffuse gray-brown breast band. Resident and extremely localized, restricted to the Congo River and a handful of its tributaries, breeding colonially in sandbanks. Despite being fairly common, the species’ vocalizations are unknown. Sand Martin is larger than Congo Martin and has a bolder breast band delineating a white throat; Brown-throated Martin has a dark throat.
