Speckled spinetail

The speckled spinetail (Thripophaga gutturata) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela.

The spectacled spinetail is 13 to 15 cm (5.1 to 5.9 in) long and weighs 13 to 17 g (0.46 to 0.60 oz). Adults have an ochraceous brown supercilium, ear coverts, and malars; the last two have dark brownish speckles. Their crown is dark chestnut that becomes dark brown on the hindcrown and upper back. Their lower back is a richer brown that continues with a rufescent tinge on the rump and uppertail coverts. Their tail is rufous; despite the species' "spinetail" name, the feathers are rounded. Their wings are dark chestnut with an ochraceous bend and dark fuscous tips on the flight feathers. Their chin is dull yellow, their throat and breast tawny-buff with dark brown triangular spots, and their belly, flanks, and undertail coverts tawny-buff with fainter spots. Their iris is pale yellowish to brown, their maxilla black to gray, their mandible gray to blue-gray (often with a pinkish base), and their legs and feet olive to brownish yellow. Juveniles have a brown crown (not chestnut), a grayish olive back, and few or no spots on the underparts.
