Piculet de Lafresnaye

Identificación

Lafresnaye's piculet is 9 to 10 cm (3.5 to 3.9 in) long and weighs 9 to 10 g (0.32 to 0.35 oz). Adult males of the nominate subspecies P. l. lafresnayi have a dark olive-brown cap with red spots on the forehead and whitish ones on the rest of it and the nape. Their face is grayish buff with brown streaks or spots and a pale stripe behind the eye. Their upperparts are dark green or brownish green with yellowish green bars. The upper side of their tail is blackish; the innermost pair of feathers have mostly white inner webs and the outer three pairs have a large white area near the tip. Their chin and throat are buffish white with narrow black marks. Their underparts are pale yellowish white with wide black bars. Adult females are identical but for whitish spots on their entire crown. Juveniles are similar to adults but duller overall, greener above, and less evenly barred below.<p>The other three subspecies of Lafresnaye's piculet have yellow-orange spots on the forehead instead of the nominate's red ones. In addition, P. l. punctifrons has a darker face and narrower bars on its underparts than the nominate. P. l. taczanowskii has a blacker crown and wider, more irregular, dark barring on its underparts. P. l. pusillus has a slight rufous tinge to its upperparts, narrow dark bars on its underparts, and a mostly unbarred center of the belly.

Taxonomía

Lafresnaye's piculet has these four subspecies:<p>What is now Lafresnaye's piculet was for a time treated as a subspecies of the bar-breasted piculet (P. aurifrons). Subspecies P. l. punctifrons was at one time treated as a separate species. What is now the Orinoco piculet (P. pumilus) was previously considered to be a subspecies of Lafresnaye's piculet, and they are now thought to form a superspecies.
