March 16-18-2016-The Swainson's Hawks Keep Coming Through Town

Leader:

March 17-Wes Hetrick assisted by Judy Davis, Laura Webb, Rose Leong
March 18-Rose Leong assisted by Hal Cohen, Wes Hetrick, Judy Davis, Pam Albers

Migration:
March 16-462 Swainson's Hawks
March 17-113 Swainson's; 11 Turkey Vultures
March 18-412 Swainson's Hawks

Discussion:
Continued caterpillars adds up to continuing hawks. Yesterday evening we had between 800 and 1,000 hawks on the ground and in the air. Today only 412 migrated. Our expectation for tonight through tomorrow are hundreds of hawks already in the valley and hopefully new birds arriving. Below is a site for the broadcast on CBS a few days ago.

Evening Watch:
Over 200 hawks are in again near the Date Farm. This might be a low count. There are probably a few hundred more.

Prediction:
Light wind tomorrow so hawks will probably descend into the fields off of Borrego Valley Rd. to feed. They will most likely migrate around 9a.m.

  1. I'm planning on going there tomorrow. Would 10 a.m. be too late to see the hawks?
