Golden-spangled piculet

The golden-spangled piculet (Picumnus exilis) is a small bird belonging to the woodpecker family, Picidae, specifically within the subfamily Picumninae. This species is widely distributed across several South American countries, including Brazil, Colombia, French Guiana, Guyana, Suriname, and Venezuela. Its presence spans a diverse array of wooded environments, from dense rain and cloud forests to secondary growth, bamboo thickets, mangroves, and even the edges of savannas.

Description and Characteristics

Measuring between 9 to 10 cm in length and weighing between 8.5 to 10 grams, the golden-spangled piculet exhibits subtle sexual dimorphism in its plumage. Adult males are distinguished by a black cap and nape adorned with red spots on the forehead and white speckles on the crown, while adult females display white spots across their entire crown. Both sexes share yellowish-white faces with dark speckles and a pale stripe behind the eye. Their upperparts are typically olive green, with darker centers to the feathers, and their wings feature brownish-green primaries and secondaries with yellow-green edges. The underparts are a pale yellowish hue, marked with blackish bars that become more spot-like on the belly. The beak has a black upper mandible and a black lower mandible with a silvery base, and their legs are grayish, sometimes with a green or blue tinge.

Distribution and Habitat

The golden-spangled piculet inhabits a broad geographic range and can be found in various elevations, from sea level up to approximately 1,900 meters in the tepui region where Venezuela, Guyana, and Brazil converge. The species is a year-round resident throughout its range, with no known migratory behavior.

Behavior and Ecology

Information regarding the golden-spangled piculet's diet is not fully detailed, but it is known to consume ants. Foraging primarily occurs in the lower strata of the forest, typically below 5 meters, where individuals often forage from small branches, sometimes adopting an upside-down posture. They are generally observed foraging alone or in pairs, occasionally joining mixed-species foraging flocks. The breeding biology of this species is not extensively documented. However, nesting has been recorded between December and March in Venezuela and Suriname, with nests being excavated in soft wood, such as in stumps. Vocalizations are described as a "tsilit, tsirrrr" and an "extr. high, thin 'see see suw.'"

Conservation Status

The International Union for Conservation of Nature (IUCN) has classified the golden-spangled piculet as Least Concern. While the species possesses a very large range, its population size is unknown and is believed to be decreasing. No immediate threats have been identified, and the species is known to inhabit several protected areas. It is noted that due to its tendency to occupy more open and sometimes disturbed habitats, human activities might potentially lead to an expansion of its range. The species is considered poorly known by researchers.
