Goose at Kew Gardens, London (1 Viewer)

I just wondered what the bird on the left is. Seen at Kew Gardens at the end of May so possibly not completely wild, it looks a bit bigger than the Greylag also shown.
Could it be a Greylag x Bar-headed hybrid or is it just an unusual variation of Greylag?

The right hand bird is not a Greylag, looks more like Lesser Whitefront or Lesser whitefront hybrid to mee!

Any more Pictures of the righthand bird? lefthand bird is Emperor Goose, but righthand bird looks like a hybrid whitefront species x barheaded goose on first glance (This type of hybrid is very whitefront-like)

What about emperor x whitefront sp Joern? Have you ever seen that combination?

The hybrid Bar-headed x Greater whitefront you have linked has seemingly a much lighter back (Bar-headed influence for sure) than the subject hybrid. Emperor being darker backed than Bar-headed...well you see what I mean...just a suggestion!

Emperor x whitefront I have seen so far look different:

scroll down on this page on emperor goose, last bird is hybrid emperor x greater whitefront:

This individual here is probably emperor x lesser whitefront:

The shade of the Back of hybrids Whitefront x Barheaded goose seems to vary between individual birds, but I do not hae a photo series to show this.

Here is a photo of a hybrid Lesser whitefront x barheaded Goose (with a lesser whitefront in front), captive birds with known parentage, photographed by Gentoo:

On my screen the beye ring looks yellowish on the hybrid bird, if this is not due to the photo it might suggest LWF origin.

It probably won't help but here is the only other shot I took of these two geese.

[By a strange coincidence I saw a couple of 'wild' Emperor Geese a few days ago, at South Walney. Apparently a group of about a dozen are known escapees.]

Found another Shot of "your" Hybrid Whitefront; together with a Bar-headed Goose.

I think it is Greater whitefront x Bar-headed Goose, like this one close to the Bar-headed goose probably also is:

This is interesting-I was alerted to this by friends: it seems there are at least 2 birds involved , one at st james which has a slightly longer bill and no clearly yellow eyering, and another one at Kew with a slightly shorter bill and a clear yellow eyering....

photos of both from Flickr:

so maybe we have both combinations :
Greater x barhead at St James
and Lesser x Barhead at Kew

To be really sure, We d need the DNA here I guess

I photographed this goose in St James' Park about 3 weeks ago. It was associating with Bar-headed Geese and close to Greylags. As I didn't see any other Anser species, I presumed it was a Bar-headed x Greylag, and that the white near the bill came from the Bar-headed?
