Re: GGAS First Friday Bird Walk, August 4, 2017 to Jewel Lake, Tilden

George A Suennen


Thanks for leading another interesting Bird Walk. Learned a lot about hummingbirds and their migrations and influence on flower evolution.

I posted my photos from the walk at:

Lots of photos of the Kingfisher. Also saw many young juveniles: Robin, Towhees, Goldfinch, Turkey, and Sparrow.

Also saw a few Crows and a couple of Double-crested Cormorants that weren't on your list.

Best to All,
