Gilded Flicker

The gilded flicker most frequently builds its nest hole in a saguaro (Carnegiea gigantea), excavating a nest hole nearer to the top than to the ground. Less frequently, they will also nest in desert dry washes with Frémont's cottonwood (Populus fremontii) or willows (Salix sp.). Cavities in saguaros are excavated one year before they are inhabited. The saguaro defends itself against water loss into the cavity of the nesting hole by secreting sap that hardens into a waterproof structure that is known as a saguaro boot. Northern flickers, on the other hand, nest in riparian trees and very rarely inhabit saguaros. Gilded flickers occasionally hybridize with northern flickers in the narrow zones where their ranges and habitats overlap.

The gilded flicker's diet mostly consists of ants, as well as other insects such as beetles or termites. They forage on the ground by picking up insects or using their tongues to probe anthills. They also feed on fruits and berries.
