Northwestern Amazon Basin

Typical Environment

Occurs in the lowlands of northeastern Colombia, southern Venezuela, and northwestern Brazil. It frequents river-edge scrub, young secondary growth, and seasonally flooded thickets along major rivers. The species also uses white-sand (campinarana) woodlands and open-canopy forest edges. It typically keeps to the midstory and canopy, moving through mixed-species flocks.

Useful to know

The brown-headed greenlet is a small canopy-dwelling member of the vireo family that forages methodically among leaves for tiny arthropods. It favors river-edge thickets, island scrub, and white-sand woodlands in the northwestern Amazon. Like many vireonids, it weaves a neat cup nest suspended from a branch fork. Its clear, simple whistled phrases can be heard even when the bird stays mostly hidden in foliage.

Behaviour

Temperament

secretive but active

Flight Pattern

short rapid wingbeats through dense foliage

Social Behavior

Usually found singly, in pairs, or small family groups and commonly associates with mixed-species flocks. Pairs are presumed monogamous and defend small foraging territories. The nest is a delicate hanging cup attached to a forked twig, where both parents participate in care.

Migratory Pattern

Resident

Song Description

Delivers a series of clear, whistled notes and short phrases reminiscent of other vireos. Calls include soft scolds and chips given while foraging and maintaining contact in dense cover.

Brown-headed gull

The brown-headed gull is a small gull which breeds in the high plateaus of central Asia from Tajikistan to Ordos in Inner Mongolia. It is migratory, wintering on the coasts and large inland lakes of the Indian Subcontinent. As is the case with many gulls, was traditionally placed in the genus Larus.

Brown-headed jewel-babbler

The brown-headed jewel-babbler, also known as the dimorphic jewel-babbler or brown-capped jewel-babbler, is a jewel-babbler in the family Cinclosomatidae. It is now usually considered to be distinct from the blue jewel-babbler, separated altitudinally and by varying behaviour, calls and female plumage.

Brown-headed nuthatch

The brown-headed nuthatch is a small songbird endemic to pine forests throughout the Southeastern United States. Genetic analyses indicated low differentiation between northern and southern populations in Florida, but the study also found lower genetic diversity among south Florida populations that may be a result of the increased habitat fragmentation that was documented. The Bahama nuthatch was formerly considered a subspecies (S. p. insularis), has since been reclassified as its own separate species. Two recent studies assessing vocalizations in Bahama and continental nuthatch populations found important differences. One of the studies also demonstrated that continental and Bahama populations did not respond aggressively to calls of the other population. This type of call-response study is often used to help define cryptic species.

Brown-headed paradise kingfisher

The brown-headed paradise kingfisher, also known as the russet paradise kingfisher, is a species of bird in the family Alcedinidae. It is endemic to the lowland forest in the Bird's Tail Peninsula. Its natural habitats are temperate forests and subtropical or tropical moist lowland forests. Like all paradise kingfishers this bird has colourful plumage with a red bill and distinctive long tail streamers. No subspecies are distinguished.
