Notes- \u3ci\u3eNebraska Bird Review\u3c/i\u3e March 1991

Swainson\u27s Hawks. On Saturday, 29 September 1990, I witnessed a mass migration of Swainson\u27s Hawks. The weather was clear, with large cumulus clouds, approximately 75°F. At about 3:30 pm, I noticed several Swainson\u27s traveling south over the Carpenter Ranch (20 miles north of Henry in Sioux County). For the next 45 minutes, I counted 176 Swainson\u27s. One thermal contained 62 birds, soaring to an estimated 3800 feet (National Weather Service data on base of clouds). Once near the clouds, the birds would peel off and head south, with wings folded and at speeds clocked via auto at 55 mph. How long before 3:30 this was occurring was unknown. Three accipiters were also observed. It was very exciting-a first for me. -----Stephen Kerr, Box 327, Gering, NE 69341 Holt County Sightings.
