Hybridization in Birds | BirdForum


I am also looking for nice pictures of hybrids….

Don’t know how nice they are but here’s my photos of a Bullock’s x Baltimore Oriole Hybrid:

BUOR X BAOR TAIL.jpg

These were taken in April 2016.

Last year, September 2020, I had another male BUOR x BAOR on the feeder; the photo was a tad bit blurry but I still have it.

As I understand, taken from Sibley’s, only the males are identifiable by their “oddly plumage”. The inference seems be “a confusing array of intermediate plumage” attributed to the different molting times(?); BUOR during or after migration (Sep-Nov), BAOR on the breeding grounds (Jul-Aug).

From my photos, the oriole’s “oddly plumage” is found on the head, coverts, and scapulars(?). The tail maybe another indicator but the photos appear to lack evidence…..black showing at the undertail coverts?

Correct me if I’m wrong.

Taken from your Icteridae page, here’s the distribution map of the BUOR/BAOR with my location; the blue dot in the yellow area of the map, which happens to be near the middle of the Central Flyway.

Elsewhere, on the subject of species, Jente included a video titled “What is a Species?” in his blog post; The Herring Gull Complex is not a ring species. The video is # 13 in the Crash Course Zoology of the CrashCourse series. Thought it was worth posting here…….maybe other neophytes, such as myself, are in need of an education. A good taxonomic primer?
