In Between Waves

Migration Today:
Swainson's Hawks-6
Turkey Vultures-1

Discussion:
Cool morning with scattered clouds and a slight breeze. At 8:50A the Swainson's Hawks lifted off from the Roadrunner Club. The TV took off in the same direction.

Question:
Mating flying ants
What is aerial feeding? Often the Swainson's Hawks fly about and pounce on ants or other insects in the air. After a rain and a warming trend, winged females and winged males are produced. The ants will fly fairly high and copulate in the air. Females will drop to the ground and begin a new colony. The males die shortly after mating. Three days ago we had over 200 feeding Swainson's Hawks. 

Evening Watch:
Swainson's Hawk pouncing on flying ants
Only 28-30 Swainson's Hawks were observed coming to roost near the day site on Di Giorgio Rd. Twelve Turkey Vultures were seen earlier, roost site unknown.

Prediction for Tomorrow:
The wind should be light tomorrow so take off from the day site should take place around 8:30A
