I noticed that birds didn't drink the water until it went further downstream where the temperature wasn't as warm. I'd like to visit this spot during a cold winter norther.
As for birds, I saw a lot of nice ones, but nothing unusual. At least 4 Redheads...
I wish I had thought to photograph some of the interesting flora, all in bloom, but I didn't. One thing that intrigued me was the deep reddish Desert Willow. I must get me one. Another large shrub/small tree looked like a legume but the blooms were yellow brush-like. I've seen acacias with white brush-like, and with round yellow balls, but I don't remember seeing this shape in yellow. I'll have to research it and see what it is. Oh, I just remembered, I did take a bad photo of it. Here it is.
UPDATE: The above tree has been identified as a Screwbean Mesquite.
