Warbler Identification: Orange-crowned vs. Tennessee

Just as with the Bay-breasted and Blackpoll identification challenge, the challenge when identifying Orange-crowned and Tennessee comes into effect only when dealing with first fall Tennessee Warblers.  In the eastern United States, Tennessee Warblers are one of the most common warblers.  Due to many birders wanting to see Orange-crowned they misidentify the common Tennessee as an Orange-crowned.

Orange-crowned Warbler

Adult

  • blurry gray streaking down the sides
  • bright yellow eye-arcs
  • olive back
  • bright yellow undertail coverts
  • plain greenish wings
  • long tail creates a longer look than Tennessee

blurry streaking on the sides and chest, and the long tail

First Fall

  • grayish head contrasts with yellow chest and olive back
  • blurry gray streaking on chest and down sides
  • yellow undertail coverts contrasting with white belly
  • very weak wingbars

Tennessee Warbler

First Fall:

  • Yellowish from head down to belly with white undertail coverts
  • weak, yellow wing bars
  • fairly strong eye-line with a yellow supercillium
  • Short-tailed:  not much tail from the end of the undertail coverts to the end of the tail
