456 Birds of Colorado 
upper mandible, legs pale yellow-brown. Length 5-25; wing 2.80; 
tail 2-0 ; culmen -40; tarsus -70. 
In autumn the male is very different, the black cap is entirely absent, 
and the upper-parts are olive-green, slightly streaked with black in 
the middle of the back, the tips of the coverts tinged with olive ; below 
paler olive-green, becoming white on the under tail-coverts. 
The female is somewhat like the fall male, but is more distinctly 
streaked on the crown and back, while below it is paler, often white 
on the centre of the abdomen, and streaked laterally with dusky. 
Distribution.—Breeding far north from Alaska and Labrador to 
Michigan and northern New England, in winter southwards through 
the West Indies to northern South America as far as northern Brazil 
and Heuador. 
The Blackpoll cannot be considered anything but a straggler on 
migration in Colorado. A number were seen and one female obtained 
near Denver, May 17th, 1873, by Henshaw ; Henderson saw one at 
Boulder on May 7th, 1905, at very close range ; and Hersey obtained 
one May 6th, 1908, at Barr; Allen & Brewster saw two and obtained 
one near Colorado Springs on May 8th and 9th, 1882; and Cooke 
notes it in his migration tables.at Fort Lyon, May 8th, and Loveland 
May 12th; there is no example in the Aiken collection. 
Minot states « local summer resident at Seven Lakes,”’ on the southern 
slopes of Pikes Peak. This breeding record has never been confirmed 
and is «a long distance from Mackinac Isle, Michigan or Manitoba, 
the nearest recorded portions of the breeding range, and even Manitoba 
seems doubtful. It will be perhaps safest to neglect the Minot record 
until further verified, and consider the Blackpoll a rare straggler on 
migration, and not a breeding resident.
