I couldn't match this to any common AZ woodpeckers but I think it is a gilla. I saw this at the botanic garden in Scotsdale/Phoenix- brown head with small red crown.
Posted the male the other day. This is the female.
Near Lake Lagunitas
On Giant Sequoia in Mariposa Grove
Poor pictures, but I think these are good enough for the ID.
One by Eddy Lake beach area.
The woodpeckers, piculets, wrynecks, and sapsuckers are a family, Picidae, of near-passerine birds. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar, and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known to live in treeless areas, such as rocky hillsides and deserts.
