and wary that its daring proximit}- is often not suspected. The 

 eggs are usually laid in the early part of May, in an open nest 

 compo.sed of sticks and small twigs, frequently unlined. 



Subgenus Asti'R Lacepede. 



140. (334). .Iccipiter africapillus (Wils.). American Goshawk. 

 The American Goshawk is a rather 'rare and somewhat irreg- 

 ular winter resident in Iowa. It occurs from November to April, 

 and has been recorded from most sections of the state. It is a 

 handsome species, bold and dashing in its habits, feeding princi- 

 pally upon game birds, rabbits, etc. It is usually found in or 

 near the woods. W. H. Bingaman reports it as "quite common 

 in winter" (Kossuth). A specimen in my collection was taken in 

 January, near Forest City (Winnebago). 



Genus Parabuteo. 



141. (335). J^arabiitco U)iici7u-tus Iiarrisi {A\\(\.). Harris Hawk. 

 This strikingly marked Hawk is an inhabitant of the southern 



border of the Ihiited States from Mississippi to Lower California, 

 and south to Panama. Its admission to the Iowa list is based 

 upon a single specimen captured in Van Buren county, near Hills- 

 boro. Walter G. Savage writes concerning it, February 25, 1904: 

 "Nine years ago a trapper caught one in a steel trap and brought 

 it to me. This is the only one that I can positively identify in 

 our locality. My father took this Hawk and now has a fine 

 painting from it, true to nature. It is identical with your de- 

 scription, and also Cones'. It is surely a Harris Hawk." 



Genus Buteo Cuvier. 



142. (337). Buteo borcalis (Gmel.). Red-tailed Hawk. 



The Red-tailed Hawk, the common "Hen-hawk," is a common 

 summer resident and breeds in all parts of the state. South of 

 the middle line of the state the Red-tail is generally resident 

 throughout the year; at least many individuals remain during 

 the winter except during very severe weather. They become 

 common in all sections by the latter part of February or first of 

 March, and the eggs are laid by the first of April (sometimes 

 early in March) in southern Iowa, while in the northern part of 

 the state sets are rarely completed before the last week of April
