    Hermit Thrush Identification

    The Four Keys to ID

    • Size & Shape

      Hermit Thrushes have a chunky shape similar to an American Robin, but smaller. They stand upright, often with the slender, straight bill slightly raised. Like other thrushes, the head is round and the tail fairly long.

    Regional Differences

    There are three main groups of Hermit Thrushes. Birds in the Pacific states tend to be smaller, thinner billed, with dusky brown upper bodies and grayish flanks. In the interior mountain West, they are bigger, thin billed, and grayer overall with larger spots and less rufous in the wings. Eastern birds are medium sized and thick billed. They are richly colored, with a buffy wash on the flanks and under the tail.
