of chocolate and reddish-brown. Gale believed that 
only one brood was raised, but Drew states that in San 
Juan co. a first brood is hatched in Baker’s Park, at a 
comparatively low elevation, and that the parents then 
move up to timber line and raise a second brood. This 
is confirmed by Anthony.

Description.—Closely resembling Z. leucophrys, but the white super- 
ciliary stripe extending forward to the base of the bill, and the lores 
grey like the chin; the black crown-bands not extending so far down 
between the eye and the base of the bill ; iris reddish-hazel, bill yellowish 
with dusky tips, legs horny-brown. Length 6-10; wing 3-05; tail 
2-65; culmen -47; tarsus -82. 
Distribution.—Gambel’s Sparrow breeds in north-western North 
America, from Alaska southwards to Montana; migrating south in 
winter through the western states to the middle of Mexico. 
In Colorado this subspecies is only known as a migrant, arriving 
rather earlier than the White-crowned, and very quickly passing on ” 
north to its breeding grounds. It reaches Colorado Springs about the 
last week in March, and is common through April, while Aiken saw a 
flock at Limon as late as the middle of May. In the fall they arrive as 
early as September 8th, but chiefly pass through in October, and a large 
proportion are young birds with chestnut crown-bands. Other 
recorded localities are : Boulder co. (Henderson), Orchard, March 29th 
(Warren), Denver, May 20th (Henshaw), Pueblo, arriving March 18th 
(Lowe), common in October (Beckham), Baca co., April 27th to May 
15th (Warren), La Plata co. (Gilman). 
There is evidence that this species occasionally winters in Colorado ; 
Osburn states that in the winter of 1889 he found Yellow-crowned 
mingled with this Sparrow on the Big Thompson near Loveland, and 
there is a skin in the Aiken collection taken in El Paso co. on February 
27th. Rockwell also reports that Sullivan has observed a few all through 
the winter at Grand Junction, and that they often linger up to the 
middle of December.
