Fernandina's flicker
Template:Short description Template:Speciesbox
Fernandina's flicker (Colaptes fernandinae) is a species of bird and type of woodpecker, in the family Picidae. Endemic to Cuba, it has a small population of 600–800 birds, which makes it one of the most endangered species of woodpecker in the world. It is mostly threatened by habitat loss.
Description
Fernandina's flicker is a medium-sized woodpecker, ranging in length from 14–15 inches (33–35 cm).[1] Overall, it is mostly yellowish-tan, covered with varying amounts of black barring; its underwings are yellow. The male has a black mustachial stripe, which the female lacks.
Distribution and habitat
Fernandina's flicker is endemic to Cuba. Though it was apparently never common, it was formerly found across the island.[2] Now, however, it is restricted to isolated locations in nine of the country's 15 provinces: Camagüey, Cienfuegos, Granma, Holguín, Las Tunas, Matanzas, Pinar del Río, Santiago de Cuba, and Villa Clara.[3] The largest population is found in Zapata Swamp, where some 120 pairs are estimated to live, though this number may have dropped following recent hurricanes.[2][3]
Fernandina's flicker's natural habitats include dry forests, dry savanna, swamps, and pastures.
Behavior
Though not a particularly social bird, Fernandina's flicker will sometimes form loose colonies of up to 15 pairs.[1] It regularly fights with other woodpeckers.
Feeding
Like its congeners, Fernandina's flicker often forages—primarily for ants, but also for other insects, worms, grubs and seeds—on the ground.[1][4] It uses its strong bill to probe the ground and flick aside leaf litter.
Breeding
Fernandina's flicker breeds between March and June;[1] during courtship, pairs regularly engage in high-flying chases. Like all woodpeckers, it is a cavity nester. Recent fieldwork has shown that it prefers to use nest holes started by West Indian woodpeckers (Melanerpes superciliaris); the flicker drives off the original owners, finishes off the excavation work, and moves in.[4] The female lays a clutch of three to five white eggs,[1] which are incubated for a period of about 18 days. The young fledge after 22 days.[4]
Voice
Though it is regularly silent, Fernandina's flicker's calls include a repeated wicka (the onomatopoeic sound which gives the genus its common name), and a loud series of pic notes.[4]
Conservation
With an estimated population of only 600–800 birds, Fernandina's flicker is one of the most endangered woodpecker species in the world.[4] Overall, that population is declining, principally because of habitat loss.[5] Farming, logging, hurricane damage and the caged bird trade—trappers bring down whole palm trees in order to capture nestling Cuban amazons (Amazona leucocephala leucocephala)[6][7]—are combining to squeeze the remaining birds into smaller and smaller isolated tracts.[4] In addition, West Indian woodpeckers have been observed killing the chicks of Fernandina's flickers.[7]
