Bird Fact Friday – Antpittas

Adapted from pages 310-311 of Birds of Central America:

A table of different Antpittas. Illustrated by Dale Dyer.

The Black-Crowned Antpitta is a distinctive species with no close relatives in the region, specifically Cemtral and Sothern America. They are uncommon and local residents in south foothills (mainly 300 to 1200 m, locally near SL in east PA). These birds are large and robust with very short tail, long legs, and heavy gray bill. Identifiable by the bold black- and- white scaling on underparts. Note the white spots on wing coverts, and that the males have black throats. Pairs or solitary birds bound rapidly over forest floor pausing briefly to stand on fallen log or other low perch. They are generally reclusive but attends ant swarms where it forages boldly. Habitually flicks wings and tail. Song (1) a very long series of loud, sharp notes wi- i- i- i- ii- i- i- i . . . that gradually slow and drop in pitch. May continue for almost one minute. Also (2) an abrupt, low- pitched, guttural three- to ten- note rattle kuk kuk kuk . . . or wucwuc- wuc- wuc . . ..

Meanwhile, the Scaled Antpitta is found from Mexico to Southern America. It is an uncommon to rare and local resident in foothills and highlands (100 to 2850 m in north, 450 to 1650 m in south). Also home to the volcanic highlands of El Salvador (Santa Ana), and recently reported from Cerro Musún in central Matagalpa, Nicaragua. These birds are plump and short- tailed. Note the gray crown scaled with black and pale malar and lores. Underparts mostly cinnamon with variable, narrow, pale crescent dividing throat and breast. Rump and wings are rufous- brown. Juveniles are mostly dusky with fine whitish and buff streaking on crown, nape, mantle, and breast. Adults from north CA are less richly colored below. These birds hop rapidly over ground and are secretive, but may forage in open on muddy forest trails or in shaded clearings. May also attend ant swarms, but are usually solitary. They are also known to sing briefly at daybreak. Song (1) a series of low- pitched, resonant notes that start as a trill, rise in pitch and volume, then slow to form distinct, hollow, individual notes before stopping abruptly huhuhuhHUHUuhuhu hu hu hu. Compare with song of Black- headed Antthrush. Calls include (2) a low- pitched grunt or croak.

By Andrew C. Vallely and Dale Dyer

Birds of Central America is the first comprehensive field guide to the avifauna of the entire region, including Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama. Handy and compact, the book presents text and illustrations for nearly 1,200 resident and migrant species, and information on all rare vagrants. Two hundred sixty detailed plates on convenient facing-page spreads depict differing ages and sexes for each species, with a special focus on geographic variation. The guide also contains up-to-date range maps and concise notes on distribution, habitat, behavior, and voice. An introduction provides a brief overview of the region’s landscape, climate, and biogeography.

The culmination of more than a decade of research and field experience, Birds of Central Americais an indispensable resource for all those interested in the bird life of this part of the world.
