Boucard's wren (Campylorhynchus jocosus) is a species of bird in the family Troglodytidae. It is endemic to Mexico. == Taxonomy and systematics == Boucard's wren has sometimes been considered conspecific with the spotted wren (Campylorhynchus gularis) but molecular data show that they are not closely related. The species is monotypic. == Description == Boucard's wren is 17 cm (6.7 in) long and weighs 23.8 to 29.8 g (0.84 to 1.05 oz). The male has a chocolate crown, reddish nape, blackish shoulders with white streaks, a reddish-brown back with black and white spots, and a dull reddish rump. Its tail is gray-brown with dark brown bars and the outermost feathers have white tips. It has a dull white supercilium and blackish eyestripe; the rest of the face is dark gray. Its chin and throat are unmarked white and the underparts are white with black spots. Its flanks are buffy with darker bars. The female is similar but for smaller spots on the underparts. The markings on the juvenile's back are less well defined than the adult's, its throat is speckled, and its underparts are grayish with dull, diffuse, spots. == Distribution and habitat == Boucard's wren is found in south-central Mexico…
