Visitors from: Baltimore, Maryland and Washington State.

Migration Today:
Swainson's Hawks-38

Temperatures today reached 88 by 11A. The wind was calm. Once again the hawks roosted at the Date Farm and lifted off at 9:35A. They moved slowly to the northwest, taking more than an hour to complete the journey through Coyote Canyon.

Looking at previous years, the dates March 19 and March 20 come to mind. In the past 9 years we have had triple digit days for Swainson's Hawks every year during this two day period. March 19 had 7 triple digit days and March 20th had 4 triple digit days including 1,385 one day. Can we guarantee a triple digit day if you join us on March 19 and 20-probably.

Evening Watch:
At 5:40P around 200 Swainson's Hawks were spotted very high. They meandered around and finally descended onto the west side of the Date Farm. Estimates range from 160-225.

Winds should be calm tomorrow morning. At least 160 and probably more SW's will take off between 8:45 and 9:45A. Best viewing will be on Di Giorgio Rd between the RV Park and Big Horn.

Nice look at some SW's closeup today-3/14/13-HC
