Swainson’s Hawks in Borego Springs 3/27/23

Today 273 Swainson’s Hawks migrated from Borrego Springs. The location of lift-off was in old potato fields near Henderson Canyon Rd. Yesterday evening we only observed a few dozen hawks coming in late in the evening. I did not send an ALERT as we did not see big numbers, The ALERT is triggered when more than 100 hawks are observed in the evening. This evening we will send scouts to the potato fields to search for incoming hawks. There is now an abundance of grasshoppers in the area. More hawks will probably enter the valley to feast on the insects. So far only a few Sphinx Moth caterpillars have been found. In the coming weeks we expect more hawks.
