The little hybrid goose cannot be a cross between an Anser and a Branta species, as these generally have a mainly dark tail (and also often darker bills or bills with black blotches). This means with that brightly coloured bill and legs and a typical Anser geese tail it has to be a cross between two anser species. It shows a clear indication of Ross or Snow goose parentage with the white-rimmed tertials and secondaries. As the bill is very small, I´d favour Ross goose as one parent. The other then should also be a small-billed species, probably with a pink bill also. Lesser whitefront seems to fit here best, so the most likely explanation would be Ross goose x Lesser whitefronted goose."
If the person who added this comment reads this post, I would be grateful for your opinion of the hybrids shown in the other two photos, both from Whitlingham. Bird 4 looks similar to a bird seen at Swanton Morley by Dave Appleton (possible Lesser White-fronted x Barnacle) whilst the bird in photo 5 has a similar wing pattern to the first hybrid but a larger bill and overall size, perhaps Ross' Goose x Greylag? Any comments most welcome.
Pied Billed Grebe at Hollingworth Lake
Back in Norfolk with a few hours of daylight left, Gary & I headed to Titchwell to have a look at the new path and search for the Pallas' Warbler seen in the week. A Treecreeper was the only bird of note in the trees near the visitors centre, and as suspected there was no sign of the Pallas' Warbler around the meadow trail. The new hide looks interesting, and just past it three Twite flew onto the saltmarsh, feeding near some Skylarks and oddly two Chaffinches. Incidentally Gary picked up the Twite by call, which he described as a "broken Linnet". We also saw a Cetti's Warbler before more searching of the bushes around the carpark. With the light fading we called it a day.
