Abstract
NOTES
REQUEST FOR REPRINTS ON OWLS:
R.J. Clark and D.G. Smith are revising the 1975 National Wildlife Federation publication, Working Bibliography of Owls of the World, for an expanded second edition. Authors who have articles or publications on owls and wish them to be listed in the second edition, are asked to send reprints to R.J. Clark, The Owl Bibliography, Department of Biology, York College of Pennsylvania, York, PA 17405-7199.
SWAINSON’S HAWK MIGRATION: On Tuesday, October 1, 1991, I observed large numbers of hawks flying south over a farm northwest of Arlington in Washington County. From 9:30 a.m. when I first became aware of them, the movement continued for 3 to 4 hours, and involved an estimated number of over 1000 hawks. The number seen at one time ranged from 6 to 30. All birds close enough to identify were Swainson’s Hawks in the full spectrum of color variations. Some appeared nearly white with dark heads, others were nearly all black or dark-brown, and two were a dark reddish-brown. It was really a fascinating display.
