    Brown Thrasher Identification

    The Four Keys to ID

    • Size & Shape

      Brown Thrashers are fairly large, slender songbirds with long proportions—the legs are long and sturdy, and the bill is long and slightly downcurved. The tail is long, too, and often cocked upward in the manner of wrens.

      Relative Size

      Slightly smaller than a Blue Jay; slightly larger than a Northern Mockingbird.
