Imagine a woodpecker that doesn’t just cling to trees but also forages on the ground, flashing vibrant colors as it takes flight. Meet the Northern Flicker, a fascinating bird that breaks the mold of typical woodpecker behavior.
These adaptable creatures are found across North America, from Alaska to Mexico, and their unique characteristics make them stand out in the avian world.1
Northern Flickers are among the few woodpecker species that undertake significant migrations, with populations in the northern parts of their range moving southward for the winter.
Here are some facts about these remarkable woodpeckers and the secrets that make them truly one of a kind.
Exploring the Yellow-Shafted & Red-Shafted Subspecies
One of the most striking features of Northern Flickers is the variation in their appearance across their range.
The species is divided into two main subspecies: the Yellow-shafted Flicker in the east and the Red-shafted Flicker in the west. These birds differ in the color of their wing and tail feather shafts, as well as the patterns on their faces and necks.
Interestingly, where the ranges of these two subspecies overlap in the western Great Plains, they interbreed freely, producing offspring with a mix of their parent’s characteristics.(ref) This hybridization results in flickers with intermediate plumage, showcasing the fluid nature of their subspecies distinctions.
Ground-Foraging Specialists: The Unusual Diet of Flickers
Unlike most woodpeckers that primarily seek food on tree trunks and branches, Northern Flickers have adapted to spend a significant amount of time foraging on the ground. Their slightly curved bill is perfectly suited for digging into the soil in search of their favorite prey: ants.
Ants make up a substantial portion of the Northern Flicker’s diet, with these birds consuming more ants than any other North American bird species. They also feed on other insects like beetles and termites, as well as fruits and berries, particularly during the fall and winter months.
The Fascinating Behaviors of Northern Flickers
Northern Flickers exhibit an array of intriguing behaviors that set them apart from other woodpeckers. One such behavior is “anting,” where the birds spread their wings over ant mounds, allowing the insects to crawl onto their feathers.
While the exact purpose of this behavior is not fully understood, it is thought to help control feather parasites or reduce skin irritation during molting.
Another notable aspect of Northern Flicker behavior is the partially reversed sex roles during the breeding season. Males take the lead in building the nest and incubating the eggs, which are some of the smallest relative to adult body size among all bird species. However, females remain involved throughout the process, making their sex roles not completely reversed.
Conservation & Population Dynamics
Despite their wide range and adaptability, Northern Flickers have experienced a slow but steady population decline in recent decades. Factors contributing to this decline may include competition with introduced species like European Starlings for nesting sites, as well as habitat loss and changes in land use.
As we continue to study and appreciate these remarkable migratory woodpeckers, it is crucial to monitor their populations and work toward conservation efforts that ensure their long-term survival.
By protecting the habitats that Northern Flickers depend on and reducing threats to their nesting sites, we can help safeguard the future of these captivating birds.
