Compare and Contrast Sparrows

My previous post featured a Field Sparrow, so I thought it would be a good comparison to now feature a bird that is easily confused with the Field Sparrow; namely the American Tree Sparrow. There are a few key distinctions, two of which can been seen in my photograph.

  • The American Tree Sparrow has a bi-colored bill, typically black/yellow. The Field Sparrow has a pink bill.
  • The darker eye-ring on the American Tree Sparrow is bisected by the rusty brown eye-line. The eye-ring on the Field Sparrow is unbroken and bright.
  • If the chest is visible, the American Tree Sparrow has a black spot right in the center of it.
