Wayne, 8S. Oakland, BE. Macomb, 8. ‘St. Clair Cos., fairly abund. mi- 
grant. I am positive it breeds, but to my knowledge no eggs have 
been taken (Swales). Wayne Co., most com. during the latter half 
Apr. and early May, when from singles to 200 or 300 may be seen 
at one time in the air, few adults alight, but many of the juniors 
do so and some remain in suitable Jocalities until middle of June, 
four breeding records (J. C. Wood ms.) ; Highland Park, only one 
breeding record, Apr. 29, ’93 (Swales); Nankin Twp., nest ‘01, no 
eggs (J. C. Wood ms.) ; Detroit, male shot June 7, ‘07, non-breeding

deep woods (Gibbs). Kalamazoo Co., as an evidence of its rarity 
here, in over 500 nests of the Buteos robbed, only one set of this 
Buzzard was taken—May 27, °75 (Gibbs). 
Wisconsin.—Com. (Hay, Goodrich); com. in northern portion 
where it breeds in the heavy timber (King); not rare, especially in 
the oak openings: as far as my experience goes, it seems to prefer 
second growth black “jack” or “pin” oak forests (Kumlien). East- 
ern Wis., rather com. spring migrant, especially commen in fall; 
by no means com. nesting species, but is a 8. R. and breeds from 
the southern tier of counties northward. According to our obser- 
vations this is the species that flocks (Kumlien and Hollister) ; 
male and female, Sept. 9 and 21 (Ridgway); com. during migra- 
tions, more or less com. S. R., breeds in many localities (Cory), 
Dunn Co., Mr. Clark considers it on the whole uncom., but has seen 
and taken it a number of times (IKumlien and Hollister). Clair 
[Clark?] Co., a spec. taken—Cowper (King). Ontegamie Co., com. 
in large woods (Grundtaig). Waukesha Co., Pewaukee, I found
