ANDERSON — TPIE BIRDS OF IOWA. 249 



extreme. Its range is generally given as " Gulf States and lower 

 Mississippi Valley ; north (casually) to Kansas, Iowa, Illinois 

 and Pennsylvania." 



Robert Ridgway states in an article, " Harlan's Hawk a Race 

 of the Red-tail, and not a distinct species" (Auk, vii, 1890, 205): 

 " An adult specimen belonging to the Iowa College nuiseum, 

 Grinnell, Iowa, which Dr. Merriam has kindly submitted to me 

 for examination, is .so clearly intermediate between /?. harlaiii and 

 /)'. borealis that I have no longer any doubt that the former is 

 simply a peculiar variation of the latter, in which the coloration 

 of the tail is chiefly affected. In this Iowa specimen the plum- 

 age is in every respect, except the tail, that of typical B. borealis, 

 while the tail has tlie curious mixed coloration so characteristic 

 of the so-called B. /lar/aiii."' 



County records: Blackhawk — "migrant" (Walters). Linn 

 — "spring and fall migrant" (Bailey). Webster — "rare" 

 (Somes). Woodbury — specimens taken at Sioux City by D. A. 

 Talbot, showing strong melanistic character (Auk, vii, 1890, 285). 

 Winnebago — two specimens are in my private collection, one 

 brought to me Oct. 27, 1891, and another which I shot along the 

 bed of Lime Creek north of Forest City, Nov. 5, 1898. 



146. (339). Bicieo lineahis (Gmel.). Red-shouldered Hawk. 



The Red-shouldered Hawk is a tolerably common .summer res- 

 ident iw the southern part of the state, particularly in the south- 

 eastern portion; rare in the northern portion, and not reported 

 from the western part of the state. Currier reports it as a "com- 

 mon resident" in Lee county and Savage does the same in Van 

 Buren county, while Henning states that it is "occasionall}- met 

 with throughout the year" in Boone county. It probabl}- occurs 

 along the Mi.s.souri River in Iowa, as it is reported from Nebraska 

 as "not uncommon in the eastern part of the state, where it breeds 

 abundantly along the Missouri River bluflfs — Omaha, Bellevue, 

 etc." (Rev. Bds. Neb., 51). I never ob.served the species in either 

 Hancock or Winnebago counties, although I studied Hawks ex- 

 tensively in that locality. M.E. Halvorsen, however, reports that 

 he has observed it at Forest Q\\.y, and W. H. Bingaman reports it 

 as rare in Kossuth county. It is generally reported from .south- 

 ern and eastern Iowa, where it is said to elude observation by 

 keeping strictly to heavy timber in bottom lands.
