tail slightly rounded, shorter than the wing; tarsus not so long as the

A.O.U. Checklist no 417—Colorado Record—Burnett 04, p. 278. 
Description.—Male—Above finely mottled and marbled with dusky, 
tawny and grey, a few black marks on the crown and back ; primaries 
dusky with tawny spots almost forming bars; three outer tail-feathers 
dusky with the terminal third white; below mottled like the back, 
becoming paler and more mixed with white posteriorly ; a white throat 
bar; iris and bill black, legs dusky. Length 10-2; wings 6-4; tail 
5-15; culmen -44; tarsus -6. 
The female is smaller—wing 6-2; the throat bar is tawny, and the 
white of the tail is much reduced and ochraceous ; the general tone is 
lighter and more ochrey. 
Distribution.—Eastern North America from Manitoba and New 
Brunswick south through eastern Nebraska and Kansas to Texas ; 
in winter, south to the West Indies and Guatemala. 
A straggler to Colorado: only once recorded. A single example, 
greatly emaciated but in good plumage, was found dead in an orchard. 
near Fort Collins by Mrs. R. J. Tenny, about September 14th, 1903. 
It was determined at Washington to be this species, and is now pre- 
served in the Museum of the Agricultural College at Fort Collins.

Nostrils tubular and cylindrical, opening rather forwards; rictal 
bristles well developed ; tail rather short and slightly rounded ; tarsus 
bare except just at the joint, longer than the middle toe without claw.

geographical races. 
A. Darker and more richly coloured. P. nuttalli, p. 243.
