Goldeneye x Hooded Merganser hybrids are not infrequently reported in North America, though in most cases the Goldeneye parent is a Common Goldeneye. This Goldeneye parent of this bird is believed to be a Barrow's.

This striking bird has proved quite popular and many birders have travelled to see and photograph it.


You don't see this guy every day!

Hi Dave,
In my experience
Hooded Merganser x Common Goldeneye in general shows greenish head gloss, more white on scapulars and paler flanks; some individuals also with odd white markings on the head (Differing from both those of Hooded merganser and Common goldeneye).

Thanks Joern - I take it then that this is probably Hooded Merganser x Barrow's Goldeneye as the photographer had suggested. Is that a combination you've come across before? I don't recall seeing any photos before.

There are more photos in the web, but I think most, if not all, are the Lake Merrit bird. See here for example:

So I think it might be possible that other hybrids of that combination show some odd white markings on the head; paralel to some Hooded merganser x Common goldeneye..
