Pale-billed woodpecker
The pale-billed woodpecker is a large woodpecker species found from Mexico to Panama, inhabiting various forested landscapes including lowland tropical evergreen forests. It is characterized by its black upperparts with white or buffy white stripes, a long ivory-yellow bill, and a red head with a bushy crest in adult males. Primarily feeding on the larvae of wood-boring beetles, this species plays a role in forest ecosystems by excavating dead trees for nesting and foraging.

About Pale-billed woodpecker
The pale-billed woodpecker (Campephilus guatemalensis) is a distinctive species of woodpecker found across a broad range from Mexico to Panama. This bird inhabits the interior and edges of various forest types, with a particular preference for lowland tropical evergreen forests, but it also occurs in deciduous forests and mangroves in drier regions.
Physical Characteristics
Measuring between 35.5 and 38 centimeters in length, the pale-billed woodpecker is notable for its robust build and striking appearance. The nominate subspecies, C. g. guatemalensis, weighs between 263 and 282 grams, while C. g. regius is slightly lighter, ranging from 205 to 244 grams. Both sexes share black upperparts adorned with vertical white or buffy white stripes on the sides of the neck that extend onto the back, often forming a 'V' shape. Their tail is dull brown, and their wings are primarily black with dull brown outer primaries. The throat and upper breast are black, transitioning to light yellowish buff with narrow black bars on the underparts. A prominent feature is its long, ivory-yellow, chisel-shaped bill. Adult males are distinguished by a red head and a bushy crest, sometimes featuring a grayish-brown spot on the ear coverts. Adult females, in contrast, have a black forecrown, center of the crown, foreneck, and throat. Juveniles resemble adult females but possess a darker bill and generally dull black coloration on the sides of their heads.
Distribution and Habitat
The species is divided into three subspecies, each with a specific distribution within its overall range. C. g. regius is found in eastern Mexico, while C. g. nelsoni inhabits western Mexico. The nominate subspecies, C. g. guatemalensis, has the most extensive range, extending from Veracruz and the Yucatán Peninsula southward through Belize, Guatemala, El Salvador, Honduras, Nicaragua, and Costa Rica, into western Panama. The pale-billed woodpecker prefers forested environments and avoids heavily deforested areas. Its elevational range varies across its distribution, from sea level up to 2,000 meters in Mexico and certain parts of Central America.
Behavior and Diet
The pale-billed woodpecker is a year-round resident throughout its territory. It typically forages in the mid- to upper levels of the forest, seeking prey on tree trunks and large limbs. Its foraging technique involves excavating in decayed wood and stripping bark from dead trees. While often seen foraging alone or in pairs, it does not typically join mixed-species feeding flocks. The detailed diet is not fully documented but is believed to consist mainly of large larvae of wood-boring beetles, supplemented by termites and some small fruits.
Breeding and Vocalizations
The breeding season for the pale-billed woodpecker varies geographically, occurring from December to June in southern Mexico and between August and September in Costa Rica. Both sexes participate in excavating nest cavities, usually in large, often dead, trees, at heights of 3 to 12 meters above the ground. The clutch size is typically two eggs, and incubation is shared by both parents. Details regarding incubation periods, fledging times, and parental care are not extensively recorded. The species produces a range of vocalizations, including a variable, nasal chatter or sputter, low whining notes, and a loud bleating call. Its drumming is characterized by a loud, rapid, double rap, and occasionally, a resonant series of up to seven rapid raps.
Conservation Status
The pale-billed woodpecker is currently listed as Least Concern by the IUCN, owing to its extensive range and a substantial estimated population of at least 50,000 mature individuals. Despite this status, the population is believed to be decreasing, primarily due to habitat loss stemming from deforestation and over-logging. The species' reliance on large trees for foraging makes it particularly vulnerable to habitat fragmentation. In Mexico, populations are afforded special protection under the Mexican Official Norm NOM-059-SEMARNAT-2010.
