84 BIRDS OF COLORADO. 
404. Sphyrapicus thyroideus. Williamson’s Sapsucker. 
Summer resident; common. Breeds from 5,000 feet to the 
upper limit of the pines. In southern Colorado is most com- 
mon from 9,000 to 10,000 feet; in northern Colorado from 6,000 
to 9,000 feet includes the great bulk of the birds. Arrives the 
first week in April and eggs are laid the last half of May. 
405. Ceophloeus pileatus. Pileated Woodpecker. 
Resident ; very rare. The A. O. U. Check List gives its 
geographical distribution as “Formerly the heavily wooded 
region of North America south of about Lat. 63°, except in the 
southern Rocky Mountains ; now rare or extirpated in the more 
thickly settled parts of the Eastern States.” That it is rare in 
the Rocky Mountains of Colorado is certain, and it is not sure 
that it occurs there at all. F. M. Drew says that in southwest- 
ern Colorado “I have been told of a great big woodpecker and 
from the description think it is this bird.” (B. N. O. C. VI. 
1881, 85 and 138.) H. G. Hoskins writes that while passing 
Tuttle Ranch he saw a large crested Woodpecker that he took 
to be this species. Tuttle Ranch is only a few miles from the 
Kansas line and as this species is known to occur only a little 
farther east, it is probable that Mr. Hoskins’ identification is 
correct. 
406. Melanerpes erythrocephalus. Red-headed Wood- 
pecker. 
Summer resident; common. Breeds on the plains and up 
to 10,000 feet. Rather more common on the plains than in the 
mountains. One of the latest migrants, not reaching northern 
Colorado until the last week in May. Eggs are not laid until 
late in June. 
408. Melanerpes torquatus. Lewis’s Woodpecker. 
Resident; common. Winters from the plains to the lower 
foothills and breeds from the edge of the plains to about 8,000 
feet. Regularly passes but a few miles out on the plains, but 
has been taken in Finney County in southwestern Kansas, 
April 23, 1893, Capt. P. M. Thorne saw two at Fort Lyons 
on the Arkansas River. A very characteristic bird of the lower 
foothills and has been seen as high as 10,000 feet in southern 
Colorado, though probably does not breed above 9,000 feet. 
Performs a slight southward migration, but most of its move- 
ments are merely to retire a few feet lower during the winter 
season. Breeds late in June. 
409. Melanerpes carolinus. Red-bellied Woodpecker. 
Summer visitant ; rare, if not accidental. A southern and 
eastern species not regularly occurring farther west than central
