The crimson-crested woodpecker (Campephilus melanoleucos) is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in Panama, Trinidad, and in every mainland South American country except Chile and Uruguay.
Taxomomy and systematics
The crimson-crested woodpecker was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other woodpeckers in the genus Picus and coined the binomial name Picus melanoleucos. The specific epithet melanoleucos combines the Ancient Greek melas meaning "black" with leukos meaning "white". Gmelin based his description on the "buff-crested woodpecker" from Surinam that had been described and illustrated in 1782 by the English ornithologist John Latham from a specimen in the Leverian Museum in London.
The crimson-crested woodpecker was for a time placed in genus Scapaneus but this was merged into the genus Phloeoceastes by James Peters in 1948. The genus Phloeoceastes was itself merged into the current genus Campephilus by Lester Short in 1982. The crimson-crested woodpecker has three subspecies:
Subspecies C. m. malherbii has a gray rather than ivory bill and more red around the eyes than the nominate. Their underparts are a more extensive and deeper cinnamon-buff. Subspecies C. m. cearae is almost identical to the nominate but is smaller and has a disproportionately shorter tail.
Behavior
Feeding
The crimson-crested woodpecker forages at any level of the forest, though it appears to favor the mid-level. It pecks, probes, digs, and scales bark to reach its prey, which is mostly insects such as beetles, butterflies and moths, and ants, both adult and larval. Some individuals have been observed feeding on termites, and small berries and seeds are also part of their diet. It often feeds on smaller branches than other similar-sized woodpeckers. Pairs typically forage together though they may be separated by several meters.<!--This website account uses Kilham and Cornell as a primary source and therefore is redundant; another of its sources is Wikipedia, which makes it circular.-->
Breeding
The crimson-crested woodpecker breeds from November through January in Panama and February to April in Suriname; their season in Trinidad includes April and that in Colombia includes February. Their nesting season elsewhere has not been defined. Both sexes excavate the nest cavity, usually in a large-diameter tree, and drum and call to each other during the excavation period. One known clutch was of two eggs. Both parents incubate the eggs and provision nestlings and fledglings. The incubation period and time to fledging are not known.
