These birds are everywhere in north central Phoenix now. There was a large stand of Mexican fan palms near my house where about 15-20 of them lived. When the house was getting ready for sale they trimmed all the palms so most of them had relocate. I put up a bird feeder recently to see if I could attract any and so far a couple pairs have shown up. Below is the best pic I have gotten yet, they are looking right at me because I just walked outside (slowly) to take the pic.
