Black-cheeked woodpecker

The black-cheeked woodpecker (Melanerpes pucherani) is a striking bird species belonging to the Picidae family. Its range extends from southern Mexico down to Ecuador, inhabiting a variety of forest environments.

Description and Identification

Adult black-cheeked woodpeckers typically measure between 17 and 19 cm in length and weigh between 42 and 68 grams. The sexes exhibit similar plumage except for their head patterns. Males are distinguished by a golden yellow forehead and a red crown and nape. Females, in contrast, possess a white to buffy white forehead, a black central crown, and a red hindcrown and nape. Both sexes share black markings around the eyes that extend down the neck, and a white line behind the eye. Their upper backs are barred black and white, while the lower back and uppertail coverts are whitish with a pale buff tinge. Flight feathers are black or brownish-black with narrow white tips and bars. The tail is black with white barring on the central feathers. The lores, cheeks, chin, and upper throat are whitish. The lower throat and breast are olive-buff with a gray tinge, and the rest of the underparts are buffish white with strong wavy bars and a distinctive red spot on the belly. Undertail coverts are yellow-brown. Juveniles are duller and browner with more diffuse barring and a smaller, paler belly spot.

Distribution and Habitat

This species is found from Veracruz and Chiapas in southern Mexico, continuing south along the Caribbean slope into Costa Rica. From there, it occupies both slopes in Panama, western Colombia, and western Ecuador, with a limited presence in Peru. The black-cheeked woodpecker prefers the interior and edges of humid to wet evergreen forests, mature secondary forests, and abandoned plantations. It can also be found in clearings with scattered trees and sometimes ventures into gardens, even those situated far from forest cover. Its altitudinal distribution is primarily between 700 and 900 meters, though it can occasionally be found up to 1,200 meters and, locally in Ecuador, as high as 1,500 meters.

Behavior and Ecology

The black-cheeked woodpecker is a year-round resident within its established range. Its diet is varied, consisting of a wide array of arthropods such as spiders, beetles, and ants, alongside aerial insects. It also consumes a considerable amount of plant matter, including fruits, berries, seeds, and catkins, and has been observed feeding on nectar from large tree flowers. Foraging typically occurs singly or in pairs, though groups may gather at fruiting trees, and the species sometimes joins mixed-species foraging flocks. They are active foragers, usually moving from the mid-level to the canopy of the forest, employing probing, pecking, gleaning, and hawking techniques. They are agile climbers, sometimes seen clinging to the undersides of branches.

Breeding and Vocalizations

The breeding season for the black-cheeked woodpecker spans from March to July. They excavate nest holes in dead tree trunks or branches, generally positioned between 4 and 30 meters above the ground. Both male and female birds participate in incubating the clutch, which typically consists of two to four eggs. The incubation period lasts for 14 days, and the young fledge approximately three weeks after hatching.

The most common vocalization of the black-cheeked woodpecker is a series of about four short, rattling trills, often described as 'churrr' or 'cherrr'. They also produce a longer, smoother rattle, a loud 'krrrr' call, and a higher-pitched piercing 'chirriree' or 'keereereek'. Both sexes engage in drumming, though not with great frequency.

Conservation Status

The IUCN has assessed the black-cheeked woodpecker as Least Concern. The species possesses a very large range and an estimated population of at least 50,000 mature individuals. However, this population is believed to be decreasing, largely due to extensive deforestation. No immediate threats have been identified, and the species occurs in several protected areas, but its numbers are negatively impacted by habitat loss.
