Uniform Woodcreeper

The uniform woodcreeper is 25 to 30 cm (9.8 to 12 in) long. Males weigh 86.5 to 121 g (3.1 to 4.3 oz) and females 95 to 118 g (3.4 to 4.2 oz). It is a large and heavy-bodied woodcreeper with a short and massive bill. The sexes are alike. Adults of both subspecies have smoky brown to olive-brown upperparts with bright chestnut to rufous-chestnut wing coverts, flight feathers, rump, and tail. Their breast is a warmer cinnamon-brown and their belly buffy brown; the latter sometimes has some indistinct fine barring. Voice: The uniform woodcreeper sings mostly at dawn but sometimes during the day. The nominate subspecies' song is a "loud series of about 6 'Weeah weeah - - weeh' notes", and that of H. u. brigidai is similar. The species' calls include "screee-wip, "nnyeah", "nyip, nyeek, nyeek, weeweweweip", "cag notes", and "whinh, whaih, whaih".
