Look at all the egrets I saw at Estrella Mountain Regional Park, down by the river. There must have been at least fifteen altogether in that one area, with others along the way. I also saw some great blue heron, a noisy kingfisher, coots, and maybe an osprey (he flew away too fast for me to be sure).
If you look carefully, you'll see both great egrets and snowy egrets. The great egrets are bigger and longer-necked, with yellow beaks and black legs. The snowy egrets have black beaks and yellow feet.
