Canyon Towhee

Its skulking habits and nondescript appearance mean that it is not one of the better known birds. It is 19 to 25 cm (7.5 to 9.8 in) long and plump, and has a noticeably long tail, at 8.2 to 11 cm (3.2 to 4.3 in). This species weighs from 36.5 to 67 g (1.29 to 2.4 oz), though on average weigh only around 45 g (1.6 oz). Among standard measurements, the wing chord is 8.2 to 10.1 cm (3.2 to 4.0 in), the bill is 1.4 to 1.7 cm (0.55 to 0.67 in) and the tarsus is 2.3 to 2.7 cm (0.91 to 1.1 in). It is earthy brown in colour, with somewhat lighter underparts and a somewhat darker head with a rufous cap (except that birds in central Mexico have the cap the same color as the back); there is also a slightly reddish area beneath the tail. There is little sexual dimorphism.
