Scruffy Bird

I captured this scruffy little bird while waiting for a meeting. It was resting on the tip of what looks like an agave.

I don't know enough birds to tell you what kind of bird this is. But, with the whitish feathers, it looks a bit unkempt compared to other birds in darker colors. Thus, "Scruffy Bird". 

This was near the water fountain at Palms Crossing in McAllen, Texas. It was very slow to get near enough to the bird without spooking it. Once the flash started going off, it turned around and did a few poses. I'll post more later.
