Acanthidops Ridgway , 1882
The peg-billed finch (Acanthidops bairdi ) is a passerine bird endemic to the highlands of Costa Rica and western Panama . Despite its name, it is not a true finch , but now recognized as a member of the tanager family (Thraupidae), after being long placed in the Emberizidae . It is the only member of the genus Acanthidops . The scientific name commemorates the American ornithologist Spencer Fullerton Baird .
Taxonomy [ edit ]
The peg-billed finch was formally described in 1882 by the American ornithologist Robert Ridgway from a specimen collected near the Irazú Volcano in Costa Rica. To accommodate the new species Ridgway introduced the genus Acanthidops and coined the binomial name Acanthidops bairdi .[2] [3] The genus name combines the Ancient Greek akanthis meaning "spiky" with ōps meaning "face". The specific epithet honours the American naturalist Spencer Fullerton Baird .[4] No subspecies are recognised.[5]
Description [ edit ]
The peg-billed finch is a long-tailed species, 13.5 cm long and weighing 16 g. It has a distinctive long upturned bill with a black upper mandible and yellow lower mandible. The adult male is slate grey, becoming paler on the belly. The female is olive-brown above, becoming paler below and with a grey tinge to the head and upper back. She has bright cinnamon wing bars and buff supercilia . Young birds are similar to the female, but have paler plumage and weaker wing bars.
It has a dry pzeek call, and the male's song consists of high whistled notes ending with a buzz, chee shee shee shee paah .
Habitat [ edit ]
This is an uncommon bird at the edges and clearings of mountain forests, and in scrubby second growth, bamboo clumps, and bushy pastures from 1500 m altitude to the timberline. In the wet season it can descend to 1200 m altitude. Its numbers have reported to be high when the bamboo is flowering on favoured sites such as Cerro de la Muerte .
Behaviour [ edit ]
The finch is seen singly, in pairs, family groups or in mixed-species feeding flocks with other small birds such as warblers .
Breeding [ edit ]
The nest, built by the female, is a cup of plant material into which she lays typically four eggs. The female alone incubates for 12–14 days to hatching.
Feeding [ edit ]
It feeds on insects and spiders , grass and bamboo seeds. It will also squeeze nectar from flowers and juice from berries.
