Piculet castaño

Identificación

The chestnut piculet is 9 to 10 cm (3.5 to 3.9 in) long. Adult males of the nominate subspecies P. c. cinnamomeus have a pale creamy forehead, a black crown with yellow-tipped feathers, and a black nape with white-tipped feathers. The rest of their body is deep rufous to rusty brown, with the rump and belly being a bit paler than the rest. Their wings are dark brown with cinnamon to rufous edges and tips to the feathers. Their tail is brownish black; the innermost pair of feathers have a cinnamon stripe on the inner webs and the outer two pairs a cinnamon stripe on the outer webs. Their iris is brown, the beak blackish, the bare skin around the eye yellow, and the legs gray. Adult females are identical but with no yellow on the crown and white spots only on the hindcrown and nape.<p>Subspecies P. c. persaturatus is a richer and darker chestnut than the nominate, and has brighter wing edging and less defined chestnut stripes on the tail. Its females have white spots on their entire crown. P. c. perijanus is similar to persaturatus but a little lighter, and the female's crown spotting is heavier. P. c. venezuelensis is as dark as persaturatus but with a cinnamon-tawny forehead, and the female has white spots only on the crown, not the nape.

Taxonomía

The International Ornithological Committee assigns the chestnut piculet these four subspecies: <p>BirdLife International's Handbook of the Birds of the World and the Clements taxonomy split a fifth subspecies, P. c. larensis (Aveledo, 1998), from P. c. venezuelensis.<p>This article follows the four-subspecies model.

Comportamiento

The chestnut piculet is a year-round resident throughout its range.<p>The chestnut piculet forages actively at all levels of it habitat but tends to stay in dense vegetation. It is typically seen singly, in pairs, or in small family groups and joins mixed species foraging flocks. Its diet has not been studied but is assumed to be ants and other small insects.<p>The chestnut piculet's breeding season appears to include at least from December to March, but nothing else is known about its breeding biology.<p>The chestnut piculet's song is "a series of 3-8 high-pitched notes ti.ti.ti.ti.ti descending in pitch".
