Is a pine Siskin a Finch?
The pine Siskin is a very small finch that moves unpredictably between habitats from year to year. It can be abundant in an area one year but totally absent the next. This irregular movement is related to food sources - particularly the yields of hemlock, pine, and birch seeds and buds. This songbird is a sociable species that often joins flocks of goldfinches.
