The pine siskin is a common bird identified by their yellow wing patch. They typically move in large, active flocks and are regular visitors at backyard bird feeders.
Pine siskins eat seeds from pine, cedar, and spruce trees. Occasionally, pine siskin can be observed feeding on mineral-rich road salt, ash, and even newly poured cement. Pine siskins will sometimes posture over food resources. If the threat fails to deter a rival, they may engage in an aerial dogfight. Pine siskins will also forage close to large beaked seed-eating birds. By doing this, the pine siskin can feed on scraps of large seeds that they cannot open themselves.
