White-bellied wren

The white-bellied wren (Uropsila leucogastra) is a species of bird in the family Troglodytidae. It is found in Belize, Guatemala, Honduras, and Mexico.

The white-bellied wren is 9.5 to 10 cm (3.7 to 3.9 in) long. Males weigh 9.8 to 10.5 g (0.35 to 0.37 oz) and females 8 to 9.1 g (0.28 to 0.32 oz). The nominate subspecies has a medium brown crown, upperparts, and tail; the rump is slightly reddish and the tail has many thin dark bars. It has a gray-white supercilium, a medium brown stripe behind the eye, and gray cheeks mottled with brown. Its throat, chest, and upper belly are gray and the flanks and vent area buff. The other subspecies differ somewhat in the intensity of the brown of the upperparts and the bars on the tail.
