The data also illustrated that there were no significant differences between male and female survival rates for the general population. The oldest yet known "yellow-shafted" northern flicker lived to be at least 9 years 2 months old, and the oldest yet known "red-shafted" northern flicker lived to be at least 8 years 9 months old.

The Guatemalan flicker was described in 1844 by Frédéric de Lafresnaye under the name Colaptes mexicanoides. [3] It was later classified as a subspecies of Northern Flicker. Studies in 2023 found that the Guatemalan flicker diverged as a species even earlier than the Gilded flicker. [4] Differences were also found in vocalizations.

Red-shafted Northern Flicker: female (left), male (right). The latitudinal variation in clutch size is influenced by the food abundance per unit area of habitat. [ 8 ] More specifically, during the reproductive season, clutch size and food abundance are directly proportional to one another relative to the density of bird populations (abundance ...
