Where To Next?

This Brown-crested flycatcher was spending some time on the tip-top of the ocotillo.  I often wonder what goes through a bird's mind when they perch for a while.  Are they simply resting or are they looking for something?  If it was Zippy, my guess would be that he has found a resting spot where he could monitor activity at his  feeder.  I suppose a hawk would be surveying for its next meal.  It's the others which pique my curiosity. 

I bought a new water dish to supplement the originals.  This one is rectangular.  I placed it a couple of feet away from the yellow one.  So far, the birds seem a little befuddled. Only a few have sipped;  most have gone straight to the original.
