HOTES ON M.GBA.IHG BROAD-WINGED HAWKS, APRIL 13, 1969 - - ELRIC H. McHEHRY
A large„.flight of Broad-winged Hawks was observed moving north over Dickinson on April 13.
Ben Feltner first noticed the hawks about ls45 PM. Ben and I then witnessed a continual
stream of migrating Broad-wings for more than an _ea_v It. is. very probable- __at..i__... -
flight had been passing over for. quite some time before we toc-___atica_ Our conservative
estimate of the number of hawks observed between lr.45 PM and 3«00 PM is 15,000. By
3i00 PM only occasional stragglers were to be seen, over Dickinsoru-
The weather that afternoon was warm, cloudy, and with a slight breeze from the south.
The birds were estimated as. flying between 20 mph and 30 mph at altitudes from treetop
level to an estimated 1000 feet. The mass were flying at about 300-500 feet. I estimated the average width of the flight to be about 500 feet_ The observations indicate
that the flight must have been at least 30 miles long. The following is a summary of
our count made during seventy minutes of observations
10 minutes at 500 per minute = 5000
30 minutes at 250 per minute = 7500
20 minutes at 100 per minute = 2000
10 minutes at 50 per minute = 500
Total = 15,000
Another interesting aspect of this mass migration was the other birds of prey observed
migrating along with the Broad-wings. The following, is a summary of those observationst
Cooper's Hawk - 1
Sharp-shinned Hawk - 7
Mississippi Kite - 5
Swainson's Hawk - 2
We noticed that the Kites flew lower than the mass of Broad-wings and the aecipiters
