The Cactus Wren (Campylorhynchus brunneicapillus) is the largest wren in United States, being between 7-9 inches long. Both sexes have a dull, rusty crown, streaked back, heavily spotted breast, tawny-colored sides and belly; wing and tail feathers barred black and white, showing a white tail band in
flight; conspicuous broad white stripe over eye. No differences between breeding and nonbreeding plumage. The tail is not usually held cocked as in most other wrens. Juveniles resemble adults but have lighter, smaller chest spots and shorter tails.
