For those who can't get out but would like to watch for hawks,
ALERTCalifornia and its vast network of "fire" cams might be useful to see
hawks moving along the foothills. There are many cameras and watching a few
cameras live may show something. Time lapse videos can be studied
afterwards also. They can be found here.
https://cameras.alertcalifornia.org/?<pos...> Look for Pine
Mountain, Johnson Peak, Mount Harvard, Sunset Peak, San Sevaine Lookout,
etc.
Given the few hawks I see over San Gabriel, I presume some come off the
west end of the Whittier Hills which implies they are coming north along
the mountains east of Orange County. There are a few cameras there,
Santiago Peak and Chino Hills, that may show limited numbers.
I will be at Mount Wilson on the east end overlooking the Santa Anita
Canyon. Last year I was at the lookout/helipad? at Chantry Flat which gives
a nice view south and east to see whether birds continue west or turn up
the canyon. If someone goes there, arrive early as the parking lot fills up
quickly. Overflow parking is available at the pack station for $20, but
mention you are there for the annual hawk watch and maybe you can get a
discount. Enjoy the food and drink afterward.
