302 TRANSACTIONS OF THE [1895 
were taken (a ring of snow was round each nest, and it was two 
feet deep on the ground); while on May 6 (794, Wholey) a set 
nearly incubated was collected, and on May 31 (’91) a second 
set was taken. Sets are 5 of 2; 4 of 3, and 4 of 4. 
Outside the breeding season, this species, like borealis may 
sometimes be seen in flocks, more often in bunches of 3 or 4 to 
10, but generally singly or in pairs. 
Buteo latissimus (343). Broad-winged Hawk. 
Resident, but not common. On April 27 (91) a set of 
three eggs was taken; on May 19 (92, Blogg) a set of two, 
and on May 28 (’92, J. H. Fisher, Jr.) a set of three nearly 
incubated. At Sandy Springs, a set of three was taken April 
9 (’91); one of three in May (’92); one of two on May 15 
(92), and another of two on May 22 (’92, Stabler). 
The three Buteos are the hawks usually shot by our farmers, 
because they are large, fly slow, and are called “hen-hawks,” 
while the much smaller, swift flying, Falcos and Accipiters, 
that may at times take chickens, escape. 
Archibuteo lagopus sancti-johannis (3472). American 
Rough-legged Hawk. 
“Along the Delaware, below Philadelphia, it is still found in 
considerable numbers from November to the end of March” 
(Birds E. Pa. and N. J., 87). It does not appear to be 
numerous in Maryland. On January 24, ’92, in Dulaney’s 
Valley, one sitting on a tree allowed me to drive slowly past 
within twenty feet of it. Dr. M. G. Ellzey says this species 
was very numerous in Howard County during the winter and 
spring of ’87—88 (Forest and Stream, xxxii, 212), At Sandy 
Springs one was shot by Mr. Leizear on March 17, ’88 
(Stabler). One was seen on the Virginia side of the Potomac, 
opposite Washington, on December 29, 79, by Mr. H. W. 
Henshaw (A. C., 88-9), and it has been taken in the District 
of Columbia (L. M. McCormick, Auk, i, 397).
