Subject: [SanDiegoRegionBirding] Swainson's Hawks This Evening-Borrego Springs
At 5pm around 90 Swainson's Hawks arrived in Borrego Springs. Our ALERT
system is activated when over 100 hawks arrive. If you would like to be
added to the
ALERT system, send a note to <hawkwatchborregosprings...> We now have
well over 500 folks on the system. We did not put out an ALERT concerning
the recent arrival as the number of hawks may be below 100.

Each evening we watch for incoming hawks 1 hour before sunset. We meet 1.8
miles north of Palm Canyon Drive on Borrego Valley Rd. We watch for hawks
as they enter the valley. The evening watch is not the official count. The
official count is made the following morning as hawks depart the valley
continuing migration north to nesting sites.

The predicted wind speed tomorrow is 1-2mph. The hawks will probably begin
kettling up between 9-10am daylight savings time. At least 50 Turkey
Vultures are in the area as well. To receive the latest information (where
the hawks are roosting and where to drive to watch their migration out of
town) drive 2.8 miles north of Palm Canyon Drive on DiGiorgio Rd to the
official count site. The leader will direct you to the best viewing
location. We are entering the prime hawk migration (March 10-30).
