Spectacled prickletail

The spectacled prickletail (Siptornis striaticollis) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Colombia, Ecuador, and Peru.

The spectacled prickletail is 11 to 12 cm (4.3 to 4.7 in) long and weighs 12 to 13 g (0.42 to 0.46 oz). It is a tiny furnariid that resembles a xenops. The sexes have the same plumage. Adults of the nominate subspecies have dull fuscous lores, a whitish supercilium and partial eyering, rufescent ear coverts with tawny streaks, and brown malars with pale buff streaks. Their crown is dark reddish brown with a hint of pale streaks. Their upperparts are rich rufescent brown that becomes redder to the chestnut-tinged uppertail coverts. Their tail is reddish chestnut; the central feathers lack barbs at the end giving a spiny appearance. Their wing coverts are dark chestnut and their primary coverts blackish brown. Their inner flight feathers are brown with rufescent edges and the outer ones mostly dark fuscous. The bend of the wing is pale cinnamon. Their chin is grizzled buff, their throat and upper breast grayish olive-brown with thin pale buff streaks and pale cinnamon on the edges, and the rest of their underparts grayish olive-brown. Their iris is brown, their maxilla dark brown, their mandible pinkish with a grayish tip, and their legs and feet grayish green to olive-yellow. Juveniles have a rufescent brown crown and more and wider streaks on the underparts than adults. Subspecies S. s. nortoni has paler lores than the nominate, with less white on the face and more obvious buff-whitish streaks on the throat and breast.
