In Between Waves

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

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.

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
