Cassin's Finch Identification

The Four Keys to ID

  • Size & Shape

    Cassin’s Finches are small songbirds with peaked heads and short-medium tails. Their heavy bills are fairly long and straight-sided, and their tails are obviously notched. Their wings are long and, when perched, the tips project farther down the tail than in other finches.

    Relative Size

    About the size of a House Finch but somewhat heftier; larger than a Pine Siskin.
