Giant Wren

Campylorhynchus chiapensis

Very large wren restricted to coastal plain of Chiapas and adjacent Guatemala. Favors open and semiopen areas with hedges, scattered large trees, stone walls, and thickets; often in and around villages and in gardens of small farms. Forages from the ground to the canopy of palm trees, mainly at low to middle levels. Occurs alongside somewhat smaller, but rather similar rufous-backed form of Rufous-naped Wren. Note Giant’s plain rufous back and wings and rufous tail (Rufous-naped Wren has boldly barred wings andblackish tail). Despite large size, can be elusive, like all wrens.

Identification

As implied by its name, the giant wren is the largest member of its family. It is 20 to 22 cm (7.9 to 8.7 in) long and weighs 43.4 to 57 g (1.53 to 2.01 oz). The sexes are similar. Adults have a black crown, nape, and shoulders. A white supercilium separates a black stripe through the eye from the crown and the rest of the face is also white. Their upperparts are bright chestnut and the tail dark chestnut; all of the tail feathers except the middle pair have a white band near the end. Their underparts from the chin to the belly are white; the belly and vent area are buff. Juveniles are similar to the adults but their underparts are whitish, not pure white.

Taxonomy

The giant wren is monotypic. Though birds in the northern part of its range are larger, the difference is too small to assign geographical subspecies.<p>It has sometimes been treated as a subspecies of bicolored wren (Campylorhynchus griseus) and may form a superspecies with it.

Range and habitat

The giant wren was formerly considered endemic to Mexico's Chiapas state, from Puerto Arista south to near the Guatemalan border. However, since approximately 2010 there have been many sightings in far northwestern Guatemala. It inhabits bushland including areas much modified by humans such as farmyards, hedgerows, and fruit orchards. It occurs only within 50 km (31 mi) of the coast and from sea level to 300 m (980 ft) of elevation.

Cabanis's Greenbul

Cabanis's Greenbul

Phyllastrephus cabanisi

Typically dull mid-sized greenbul with a long bill and tail. There is geographical variation, with the western birds more yellowish below, and the eastern birds more whitish. Usually shows a distinctive pale eye-ring. Found in the thick undergrowth and mid-story of forest at middle and high elevations, usually in small groups. The call starts with slow and chatty notes, then accelerates into a grating, up-and-down series. Somewhat similar to Gray-olive Greenbul, but larger, with a darker bill and legs and usually some yellowish tones on the underparts. Similar to brownbuls, but more olive-green on the back and yellowish below.

Oriental Hobby

Oriental Hobby

Falco severus

Small falcon, usually seen in and around forest clearings or perched up on high vantage points such as snags and telecommunication towers from which it hawks for its prey. Dark gray above with brick-red underparts and a white throat and collar. One of very few small falcons throughout much of its range; can be confused with migratory Eurasian Hobby, which lacks the reddish underparts.

Hill Swallow

Hill Swallow

Hirundo domicola

A small dark blue-black swallow with rufous-chestnut on its face and a short tail. Except for a black triangular eye-stripe extending to the bill, the entire forehead, chin, throat, and upper breast are rufous-chestnut, without any dark necklace like that of Barn Swallow, the main confusion species. Hill Swallow’s dark upperparts have a blue-green sheen that is only visible when seen up close, while the underparts are dingy white with ashy-gray on the flanks. Juveniles have duller chestnut on the face. Mainly inhabits open areas such as grasslands, reservoirs, and tea estates in the high hills above 500 meters of elevation; very rare at lower elevations. Often seen wheeling and looping in the air after insects, with a swift flight action reminiscent of a Barn Swallow with a shorter tail.
