Long-billed Thrasher
Toxostoma longirostre
This bird is slender and long-tailed, averaging 26.5–29 cm (10.5–11.5 in) in length and about 70 g (2.5 oz) in weight. It is a large-sized thrasher that is close in size to the American robin. T. longirostre ssp. sennitti is described with a grayish-brown crown with a rufous color appearing in the back, rump, rear, and shoulder. Broad white tips located on the greater and lesser primary coverts and dullish-brown with rufous brown edges on the primary and secondary coverts gives the closed wings a rufous appearance. Voice: The song is warbling and resembles other thrashers' songs but is especially rich and musical, though occasionally scratchy. Phrases are often repeated two to four times.
