Dark-eyed Juncos

If American Robins are the heralds of spring in New England, then surely the Dark-eyed Junco, also known as the “snowbird,” is the harbinger of winter.   

These small, gray, seed-eating birds in the sparrow family are most often seen in Massachusetts from fall migration in October to spring migration in April. But what many people might not realize is that juncos can be found in the Commonwealth year-round, and often breed in our conifer forests. 

How to Identify Dark-eyed Juncos 

Juncos are among the easier birds to identify. Males are a uniform slate gray on their back, wings, and head, with a clean white belly. Females can have varying amounts of brown mixed with the gray. 

 Unlike all other sparrows in Massachusetts, both males and females lack streaks or stripes of any kind on their face, breast, or belly.

Dark-eyed Junco Behavior 

Seed eaters, juncos forage on the ground, hopping along in small social groups and uttering single high buzzes and short repetitions of one note: tew-tew-tew-tew. When alarmed, juncos will fly to the nearest cover (usually a bush or low tree), flashing bright white stripes on either side of their tails as they flutter away.

Where Can I See Dark-eyed Juncos? 

Dark-eyed Juncos are regular breeders throughout western Massachusetts, east to Worcester County. They can be found year-round, often breeding in conifer forests. Their breeding and wintering numbers over the past few decades appear to be more or less stable.
