Arrowhead piculet

Arrowhead Piculat

The Arrowhead piculet, scientifically known as Picumnus minutissimus and also referred to as the Guianan piculet, is a small bird species belonging to the woodpecker family, Picidae. This species is a year-round resident found within the Guianas region of South America, with its primary known range in Suriname, and possible occurrences in adjacent Guyana and French Guiana.

Physical Description

Measuring between 9 and 10 centimeters in length and weighing 11 to 16 grams, the Arrowhead piculet exhibits distinct plumage. Adult males sport a black cap marked with a red patch on the forehead and white spots elsewhere. Their faces are predominantly dark brown with subtle white feather tips and a white line behind the eye. The upperparts are an olive brown, featuring blackish wedge-shaped centers on the feathers, a fine black bar at their tips, and a small white spot near the feather's edge. Their underparts are white with a brownish buff tinge on the belly and flanks, creating a scaly appearance due to fringed feathers. Adult females share these characteristics but lack the red patch on their forehead. Juveniles are identifiable by their plain brown crown and browner upperparts with more subdued underpart patterns.

Distribution and Habitat

The Arrowhead piculet's habitat preferences are diverse, encompassing a variety of landscapes. It can be found in mangroves, secondary forests, plantations, gallery forests, and even montane forests, indicating a degree of adaptability within its relatively small geographic range.

Behavior and Ecology

This species is a year-round resident, undertaking no significant migrations. Its diet, though not exhaustively documented, includes ants and small beetles. The Arrowhead piculet employs a foraging behavior akin to chickadees, often hanging from twigs and small branches to hammer and extract food. The breeding season extends from March to December, during which males excavate nest holes, sometimes as high as 8 meters above the ground, with some female contribution. Clutches typically consist of two or three eggs. Both parents participate in incubating the eggs for 12 to 14 days and subsequently feeding the nestlings, which fledge approximately 28 days after hatching. The Arrowhead piculet's vocalizations include a series of thin notes, often described as 'it-it-it-it...', or 'kee kee kee', and a loud twitter observed during aggressive encounters.

Conservation Status

The conservation status of the Arrowhead piculet has seen revisions, currently being listed as Least Concern by the IUCN. While its population size is not precisely known, it is believed to be stable. Nevertheless, deforestation poses a potential threat to its habitat.
