Sweetwater Wetlands and Christopher Columbus Lake

I had a late start yesterday, so didn't arrive at Sweetwater Wetlands until 11:00 -- or more importantly until it was 104 degrees. The consequence was a very quiet visit. I did see a Green Heron fly in a weed bed and a Belted Kingfisher heading somewhere cooler. Probably my best photos were a Savannah Sparrow and a couple of Mexican Mallards:

 I didn't fare any better at Christopher Columbus Lake. The few birds there were stayed pretty much deep inside the trees where they were foraging. The best there was this Yellow Rumped Warbler:
