The Pine Siskin, a member of the finch family, is closely related to the Redpoll and the Goldfinches. The Siskin is an irruptive species that can be common in mid-Michigan some winters and scarce in others.
As winter approaches, Pine Siskins become considerably plumper to help them survive. Each bird can pack sufficient seeds into its expandable esophagus to support itself through five hours of rest at -4 degree Fahrenheit temperatures.
