Cooper’s, Goshawk, Red-tailed, Red-shouldered, Broad-

H. S. Hathaway writes me that quite a few are shot for the 
bounty offered by the state during the fall flight in Septem- 
ber, which follows the southern shore. 
At Bay Ridge, Long Island, Wilmot Townsend observes: 
“T have not seen them save on the annual flights, which oc- 
curred very regularly each autumn, Sept. 24 to 27. I say 
occurred, for I have not observed them for some years past, 
—say five or six, the neighborhood being all built up and 
the birds finding no place to halt, have largely deserted us. 
1 remember the flight of Sept. 27, 1892, was marked by the 
unusual number of Broad-wings that appeared, circling as 
is their habit, by hundreds, high in the air. It was a very 
unusual flight, both as to numbers of various species ( Broad-

Trowbridge has given a great deal of time and attention 
to this phenomenon. He informs us that “at New Haven,

of hawks, and I was again fortunate enough to witness it. 
There was little wind at first, and the hawks did not appear 
until nine o’clock in the morning, when a few Sharp-shinned

and Broad-winged Hawks, both adults and young, appeared 
soaring in immense clusters. In one great flock alone there 
must have been 300 hawks, the greater part were undoubt-

Sept. 24, after a number of days of southerly winds, there 
occurred a flight which lasted from six o’clock in the morn- 
ing until noon. I was informed by several collectors, who 
were out shooting at the time, that three flocks of Broad- 
wings passed over them, and they were able to secure a num- 
ber. Sept. 18, 1890, when a large flight occurred, the day
