Description:
|
A blackbird-sized and shaped orange bird, ie. clearly an oriole. Head messy and dull orange overall with an indistinct, but clearly noticeable black eyeline; distinct black throat, poorly outlined by orange, and narrowing on lower throat; breast and vent the same dull orange as head, and belly whitish; two white wingbars—the upper one being noteably wide (not as large as on adult male Bullock’s Oriole, but larger than that of female-type Baltimore); back olive colored with dark streaking. |
Voice: |
Bird did not vocalize |
Similar species: |
Baltimore Oriole eliminated based on most characters described above, in particular the black eyeline and throat. Only other orange oriole with streaked back is Streak-backed Oriole, which never shows dark eyeline or pale belly |
Photographs or tape recordings obtained? |
No |
Previous experience with this species: |
I am very familiar with Bullock’s Oriole and have lived for the past four years in Colorado, where Bullock’s Oriole is a common breeding bird (and also where Baltimore Oriole occurs as a rare breeder) |
