FALCOxXS, HAWKS, EAGLES, ETC. 201 



note of the Red-tail is a long-drawn " squealing " whistle, which to 

 my ear suggests the sound produced by escaping steam.

Dr. William L. Ralph, in Captain Bendire's Life Histories of North 

 American Birds (p. 218), reports this species as not uncommon during 

 the winter in St. John's and Putnam Counties, Florida. He writes :

 call-note is the same, only being longer drawn out. The call of the 

 latter bird, as already stated, sounds like the squealing of a pig, or 

 ' kee-ee-e,^ and that of Harlan's Hawk like ' hee-ee-ee-e-e-ee." ' 



The Western Kedtail (S37b. B. l. calums) has been recorded from Illi-

 have been taken in Michigan.
