Pervasive and recurrent hybridization prevents inbreeding in Europe’s most threatened seabird #ornithology #seabirds @ub.edu ‪@irbio-ub.bsky.social‬ www.pnas.org/doi/10.1073/...

#BirdHybrid I am not sure what I got here...terrible pictures, my apologies, I only realized that this is a Teal after browsing pictures from Jun 20th. It is clearly in molt, it almost looks like it could be a Green-winged teal, but I do see hints of two white stripes. Hybrid?

Why do Western and Clark’s Grebe hybridize?

Some souvenirs from a recent 2 hours of birding trip to Blue Heron Lake at Golden Gate Park San Francisco. Technically probably not really great pictures, but both lifers within 100m and kind of a cool mix of species.

#BirdHybrid A duck recently posted on Fb, picture taken a couple of days ago in Switzerland. Looks like a hybrid with Scaup in it, plus Ferruginous Duck or Common Pochard. However, some aspects argue for and against one or the other. The head seems to have a purple sheen. Any thoughts?

This presumed Redhead x Ring-Necked Duck hybrid has been shared on Facebook (I can share a screenshot, if someone is interested). I would guess a Common Pochard x Ring-necked Duck hybrid should look somewhat similar....

#BirdHybrid Presumed hybrid Greylag x Barnacle goose close to the Rhine river near Ingelheim, Germany (Mar 19th 2025). However, after scanning the literature a bit more, I am trending more to Greater White-fronted x Barnacle. Any thoughts?

#Northantsbirds Thought I'd found the drake Ring-necked Duck on Aldwinkle Lake, but actually turned out to be something (arguably!) more interesting, a Ring-necked x Tufted Duck hybrid! Smart looking thing; little 'tuft', dusky flanks, mixed head-shape, wide white subterminal stripe on beak.

#BirdHybrid Recently (re-?)discovered Tufted Duck x Lesser Scaup hybrid just West of Boston, MA, at Chestnut Hill Reservoir and Hammond Pond (pictures below). Sorry for the poor quality, it stayed 200 m away from me with the Ring-necked Ducks. More at media.ebird.org/catalog?regi...
