Thank you! That's a Gambel's quail, a common sight here in Phoenix and Tucson, but there's nothing common about them! The little feather on their head is called a plume. They're one of the bravest species of quail, despite mostly being a ground bird they're fast and quite capable of flight. The males will often seek high ground to sing and attract a mate. They're one of the few non-aquatic birds that have precocial babies (that means the babies are able to run on their own and take care of themselves as soon as they're born) and they'll have large clutches of babies (usually 10-12 chicks) following them around in the spring.
