Ruby-crowned Kinglet Identification

The Four Keys to ID

  • Size & Shape

    Kinglets are tiny songbirds with relatively large heads, almost no neck, and thin tails. They have very small, thin, straight bills.

    Relative Size

    Smaller than a chickadee or warbler; about the same size as a Golden-crowned Kinglet.
