Arizona Woodpecker

November 15, 2023

The Arizona Woodpecker, a fascinating bird species native to the southwestern United States and Mexico, is the subject of our comprehensive educational blog. In this post, we will delve into the Arizona Woodpecker's size and shape, color pattern, behavior, habitat, interesting facts, ecosystem services, and the importance of conservation efforts. By learning about this captivating bird, we hope to inspire an appreciation for the wonders of nature and the need to protect our planet's biodiversity.


Size and Shape

The Arizona Woodpecker (Picoides arizonae) is a small to medium-sized woodpecker, measuring approximately 18-21 cm (7-8 inches) in length and weighing around 40-50 grams (1.4-1.8 ounces). As with many woodpecker species, this bird has a stout body and a sturdy, chisel-like bill perfectly adapted for excavating wood in search of insects.

Its wings are relatively short and rounded, while its tail feathers are stiff and rigid, providing extra support when the bird clings to tree trunks or branches. The Arizona Woodpecker's zygodactyl feet, with two toes facing forward and two facing backward, are well-suited for gripping the bark of trees and moving vertically along their surfaces.


Color Pattern

The Arizona Woodpecker's coloration is unique among North American woodpeckers, with a predominantly dark brown plumage and white barring on its back, wings, and tail. The male features a small, vivid red patch on the back of its head, while the female lacks this distinctive marking. The bird's underparts are a pale, buffy white with small, dark brown spots or streaks. Its face is mostly unmarked, with a white eyebrow line and a dark brown eye stripe.

The Arizona Woodpecker's distinct color pattern helps it blend into its woodland habitat, providing excellent camouflage as it forages for food. Its subtle yet beautiful markings make it a sought-after species for birdwatchers and nature enthusiasts alike.



Arizona Woodpeckers are primarily insectivorous, feeding on a variety of insects such as beetles, ants, and caterpillars. They use their powerful bills to excavate insects from the bark and wood of trees, often leaving behind characteristic holes as evidence of their foraging activities. Occasionally, they may also consume fruits, nuts, and seeds.

These birds are non-migratory, remaining in their habitat year-round. They are generally solitary or found in pairs, although they may join mixed-species foraging flocks during the non-breeding season. Arizona Woodpeckers are cavity nesters, excavating their nest holes in dead or decaying trees. Both the male and female share in the incubation and care of their young.



The Arizona Woodpecker is predominantly found in the southwestern United States, specifically in Arizona and New Mexico, and throughout much of Mexico. Its preferred habitats include pine-oak woodlands and mixed conifer forests, generally at elevations between 1,000 and 2,500 meters (3,300-8,200 feet). The availability of dead or decaying trees for nesting and foraging is a crucial factor in determining suitable habitat for this species.

Conservation efforts for the Arizona Woodpecker focus on preserving its woodland habitat, especially mature forests with a high prevalence of decaying trees. The maintenance of such habitats is essential for the bird's continued survival and success.



  1. The Arizona Woodpecker was formerly considered a subspecies of the Strickland's Woodpecker (Picoides stricklandi), a closely related species found in Mexico. However, recent genetic studies have confirmed its status as a separate species.
  2. The Arizona Woodpecker's unique dark brown plumage sets it apart from other North American woodpeckers, which are typically black, white, or a combination of both colors.
  3. These birds have a special adaptation called the hyoid apparatus, a long, flexible, and bony structure that wraps around their skull, allowing them to extend their tongue far beyond the tip of their bill. This helps them extract insects from deep within tree bark or crevices.
  4. The Arizona Woodpecker's primary vocalization is a series of sharp, high-pitched calls, often described as "pik" or "wip" sounds. These calls serve various purposes, such as establishing territory, attracting a mate, or communicating with other individuals.
  5. Like many other woodpeckers, the Arizona Woodpecker engages in drumming behavior, rapidly pecking on a resonant surface such as a tree trunk or branch. This drumming serves as a means of communication, typically used to advertise territory or attract a mate.


Ecosystem Services

The Arizona Woodpecker plays an important role in maintaining the health and balance of its woodland ecosystem. By feeding on insects, it helps to control pest populations that could otherwise cause significant damage to trees and other vegetation. In addition, the excavation of nest cavities benefits other cavity-nesting species that are unable to create their own nesting sites. These secondary cavity users include various bird species, such as bluebirds, swallows, and wrens, as well as small mammals like bats and squirrels.

Furthermore, the Arizona Woodpecker's foraging activities contribute to the decomposition of dead and decaying trees, facilitating the recycling of nutrients and promoting the growth of new vegetation. In this way, the Arizona Woodpecker acts as a natural forest engineer, shaping the structure and composition of its habitat.


The Arizona Woodpecker is a remarkable and unique bird species that plays a vital role in the health and maintenance of its woodland ecosystem. Through its foraging and nesting behaviors, this fascinating bird contributes to the control of insect pests, the provision of nesting sites for other wildlife, and the natural processes of decomposition and nutrient cycling. By learning about and appreciating the Arizona Woodpecker, we can better understand the interconnected nature of our planet's ecosystems and the importance of conserving the habitats that support such a diverse array of life.
