Habitat
Throughout their range, Pine Siskins typically breed in coniferous forests, although they are often found in mixed forests in the Puget Trough. During migration and winter, they can be found in many types of semi-open areas, including forest edges and weedy fields.
Behavior
Pine Siskins form flocks year round, and winter flocks may be quite large. They can be very common at bird feeders in urban areas. (Unfortunately, such dense concentrations may spread salmonella, especially when feeders are not properly cleaned.) Pine Siskins are active foragers and climb about nimbly when foraging in forest canopies and hedgerows, often hanging upside-down. They also occasionally forage on larger branches, much like a nuthatch. Like many finches, they have an undulating flight and often make aerial contact calls.
