Mérida wren explained

The Mérida wren (Cistothorus meridae), or paramo wren, is a species of bird in the family Troglodytidae. It is endemic to Venezuela.[1]

Taxonomy and systematics

The Mérida wren is monotypic.[1] Apolinar's wren (C. apolinari), grass wren (C. platensis), and it form a superspecies.[2]

Description

The Mérida wren is 10cm (00inches) long. Adults have a medium brown crown and nape with darker brown streaks, blackish brown shoulders and upper back with off-white streaks, and a blackish and brown streaked rump. Their tail is medium brown with crisp black bars. They have an off-white supercilium that is wider to the rear, cheeks mottled with brown, and off-white chin and throat. Their chest is buffy and the flanks a darker buff.[3]

Distribution and habitat

The Mérida wren is found in the Andes of Venezuela from Trujillo south to northeastern Táchira. It inhabits wet páramo with scattered bushes at elevations between 3000and. It is mostly sedentary but may move altitudinally and is thought to leave some areas during the rainy season.[3]

Behavior

Feeding

The Mérida wren forages low in the vegetation for arthropods; no details have been published.[3]

Breeding

Very little is known about the Mérida wren's breeding phenology. It is polygamous and uses "dormitory" nests for roosting but not breeding.[3]

Vocalization

The male Mérida wren has a repertoire of 20 to 25 songs that vary geographically and even among individuals in a region.[3] Some examples are https://www.xeno-canto.org/220669, https://www.xeno-canto.org/6860, and https://www.xeno-canto.org/219913.
