Okay, I'm turning into a daily bird slacker -- yesterday I was mildly under the weather, and again took no photos whatsoever.
So today I offer two goodies, this first one from last week, to make up for yesterday...

Harris's Hawk on a power pole, near the Salt River, 5/3/12.
The Harris's Hawks seem to favor power poles as perches. Often these birds take off when I stop the car to try to photograph them, but this one held its ground.
And the next photo is from this morning, a true daily bird...
(and if you're reptile-squeamish, fair warning, don't look!)

A Red-Tailed Hawk atop a saguaro with a non-venomous Red Racer (Coachwhip) snake wrapped around its neck.
Probably the hawk caught the snake and brought it up to the saguaro top for lunch, but in any event, the snake had other ideas. The hawk appeared to have the snake's front half firmly in its talons, but the snake had gotten its tail end up around the hawk's neck and tied a little loop.
After a few minutes of mutual struggle, the hawk took off and the snake fell to the ground. The hawk seemed fine afterwards -- it landed on another saguaro. Not sure if the snake could have survived the 25 foot drop, but I wasn't about to investigate!
