Spotted Wren

The spotted wren (Campylorhynchus gularis) is a species of bird in the family Troglodytidae. It is endemic to Mexico. == Taxonomy and systematics == The spotted wren has sometimes been considered conspecific with Boucard's wren (Campylorhynchus jocosus) but molecular data show that they are not closely related. The species is monotypic. == Description == The spotted wren is 17 cm (6.7 in) long and weighs 28.3 to 31 g (1.00 to 1.09 oz). Adults of both sexes have a chestnut crown and rufescent brown shoulders and back with dull black and buffy markings. The tail is gray-brown with darker bars. They have a white supercilium and a brown eyestripe above buffy white cheeks. Their chin, throat, and chest are off-white and the sides of the chest have blackish spots. The belly and lower flanks are buffy with faint barring. The juvenile's crown is dull black, the markings on the back are fainter than the adults', and the chest is pale buff without the adults' spots. == Distribution and habitat == The spotted wren is found in two areas of Mexico separated by unsuitable habitat. In the west it ranges from southeastern Sonora south to western México state and western Morelos.…
