Acorn Woodpecker or Red-Breasted Sapsucker?
Here's how to tell the difference
Acorn Woodpecker
Red-Breasted Sapsucker
Acorn Woodpecker
Melanerpes formicivorus
General appearance
The acorn woodpecker has a striking appearance with a black back, white belly, and a distinctive red crown. Its face is mostly white with a black patch around the eye and a strong, pointed bill. The wings are black with white patches visible during flight. The bird is medium-sized, with a length of around 8-9 inches.
Male vs female
Both male and female acorn woodpeckers have a bright red crown, but males have a solid red crown extending from the forehead to the nape, while females have a black band separating the red crown from the white forehead. This subtle difference helps in distinguishing the genders.
Juvenile
Juvenile acorn woodpeckers are similar in appearance to adults but with duller colors. Their red crown is less vibrant, and the black and white facial patterns are less distinct. Juveniles may also have more of a brownish tint compared to the glossy black of adults.

Sphyrapicus ruber
General appearance
The red-breasted sapsucker is a medium-sized woodpecker known for its vivid red head, throat, and chest. Its back is predominantly black with white barring, while the wings are black with white spots. Underparts are pale, and its tail is black with white outer feathers. It has a sturdy bill, ideal for drilling into trees.
Male vs female
The red-breasted sapsucker exhibits minimal sexual dimorphism, making it difficult to distinguish between males and females in the field. Both sexes appear similar in size and coloration. Generally, the red coloration is slightly more intense in males, but this can be challenging to observe without direct comparison.
Juvenile
Juveniles are less vibrantly colored than adults, featuring a mottled mix of brown and gray on their heads and less prominent red on their throats and breasts. The back and wings display the typical patterns but are duller. As they mature, juveniles gradually acquire the distinctive adult plumage.

Visual differences
The Acorn Woodpecker is 7.5-9 inches long, with a black back, white belly, and distinctive red crown (males: solid red, females: red with black band). It has a strong, pointed bill. The Red-Breasted Sapsucker, slightly smaller at 8-8.5 inches, features a vivid red head, throat, and chest. Its back has white barring, and wings bear white spots. Both have sturdy bills, but the Sapsucker's underparts are paler. Acorn Woodpeckers exhibit clear gender differences, unlike the more uniformly colored Red-Breasted Sapsucker.
Key differences and behavior
The Acorn Woodpecker and Red-Breasted Sapsucker exhibit distinct behaviors and habitats. Acorn Woodpeckers, residing mainly in oak woods, are known for their unique granary system where they store acorns in tree holes. They form large cooperative breeding groups, with shared parenting responsibilities. Their diet, predominantly acorns, includes insects, nuts, and fruits. In contrast, the Red-Breasted Sapsucker prefers moss-laden forests and urban parklands in the American Northwest. These birds drill into deciduous trees to consume sap and insects. They participate in courtship displays and use nest cavities high in trees for breeding. Both engage in cooperative parenting. Their diet mainly consists of insects and tree sap, supplemented by berries and fruit. Sapsuckers often interact with hummingbirds, which feed on the sap wells they create. Overall, Acorn Woodpeckers are highly social and storage-focused, while Red-Breasted Sapsuckers are sap-oriented and adapt well to urban environments.
