FALCONS, 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.

 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 ' kee-ee-ee-e-e-ee.' ' 



The WESTERN REDTAIT, (SS7b. B. b. calurus) has been recorded from Illi-

 have been taken in Michigan.
