Buteo borealis kriderii Hoopes. KRIDER'S HAWK. 
This western-plains race of the red-tail is a regular fall and 
spring visitant in western Wisconsin, in small numbers. 
Mr. J. N. Clark has kindly loaned us a very fine and typical 
specimen shot by himself at Meridian, Dunn County, October 
22, 1892. He states that it is of regular occurrence there in 
spring and fall, though by no means common. Three speci- 
mens, all perfectly typical, have been taken at Lake Kosh- 
konong during the past few years, one of which is preserved in 
the collection of the Oshkosh Normal School. 
Buteo borealis ealurus (Cass.). WESTERN RED-TAIL. 
Of rare, but regular occurrence in Wisconsin in the late fall. 
Six or eight specimens were procured about Lake Kosh- 
konong by Thure and L. Kumlien; one specimen, taken in 
November, 1873, was pronounced by Prof. Baird as "extra 
dark" and perfectly typical. A single specimen was taken at 
Delavan, October 19,' 1901. Mr. J. N. Clark has loaned us an 
extra fine female shot by himself at Meridian, Dunn County, 
( )ctober 25, 1893. This specimen is of solid dark color, with 
the exception of the reddish-brown blotch across the breast, 
and has an exceptionally bright reddish tail, crossed by ten 
black bars and with a wide black terminal band. This speci- 
men is probably very much like the one mentioned by Coues (1) 
as "chocolate-brown, with a great reddish blotch on the 
breast." 
Buteo liueatus (Gmel.). RED- SHOULDERED HAWK. 
In the early days this hawk was considered a common 
species by nearly all observers. At the present time it is cer- 
tainly by no means a common bird in Wisconsin, and at any 
distance from Lake Michigan seems to be decidedly rare. 
Appears to nest irregularly at different places, most often at 
points not far from Lake Michigan. Mr. Clark has taken but 
one specimen in Dunn County. April 27, 1891, and considers it 
a very rare species there. Grundtvig failed to find it in 
Outagamie County, or W'illard in Brown County. Mr. W. E. 
Snyder records but one capture from Dodge County (2). But 
few have been taken at Koshkonong since 1870, and we have 
but one specimen from Delavan.
