DUCK HAWK. 
356a. Falco peregrinus anatum. 17 inches. 
A most beautiful species, with a black patch, or mous¬ 
tache, on side of the throat from the bill; head and upper 
parts bluish gray with darker markings; under parts white, 
tinged with buffy on the lower part, and lightly barred with 
black, with the throat pure white. Their food consists mostly 
of ducks, which they always take while on the wing. It breeds 
abundantly on the Pacific coast and in some parts of Dakota 
on the rocky ledges. 
Nest. —They are not home builders as a general thing, but 
lay their three or four eggs on the gravel or bare rocks 
of ledges or cliffs. The eggs are a reddish buff color, com¬ 
pletely blotched and dotted with reddish brown. These are 
the darkest, brightest and the most beautiful of the Falcon 
eggs (2.05 x 1.55). 
PIGEON HAWK. 
357. Fcilco columbarius. 12 inches. 
A small Falcon, similar to the Sharp-shinned Hawk, but a 
much darker and stouter built bird. It is a daring little 
fellow, and will attack birds much larger than itself. It feeds 
on small birds and mice.
