Dark-eyed Juncos are birds of the ground. They hop around the bases of trees and shrubs in forests or venture out onto lawns looking for fallen seeds. You’ll often hear their high chip notes, given almost absent-mindedly while foraging, or intensifying as they take short, low flights through cover. During flock feeding in non-breeding seasons, tail-flicking (exposing outer white feathers) and calling are very frequent; bill-jabbing is rare. In most common aggressive displays the dominant bird will sleek head and neck plumage and extend the neck horizontally. A supplanting attack usually consists of dominant’s hopping forward, subordinate’s retreating. If the individual does not retreat, contestants face off a few centimeters apart.
