Crossbilled Blackcap

Had a bit of time to put a net up in the garden this morning. I caught one bird, which was yet another Blackcap!

This one was a quite different from all the others though, because it had a deformed bill, and had been eating something which had made its face go very yellow....

A right weirdo!

It was light compared with my recent Blackcaps (weighing 16.4 grams - the previous five birds coming in at 18.7, 18.7, 23.0, 18.8 and 18.5), but it had a fat score of 25 and a bit of body muscle. If it was summer, and this was a Phyllosc, I would have said the yellow on its face was pollen - but it isn't - so I haven't a clue what it has been feeding on!

Had a couple of looks along the Estuary today, the mid afternoon look revealed 12 adult Med Gulls. One was well on its way to summer plumage - yummy! None of them were today, I think the white colour ringed bird the other day has already moved in.

This bird was white 31A7, and it turns out it was ringed as a third calendar year bird on 24/06/09 at Harlingen Haven, Friesland, Holland. There was an interesting re-sighting of it on 13/05/10 on the Island of Griend (also Holland), where it was seen eating a Black-headed Gull egg! Since then it has been seen only once before I spied it, this was on 20/06/11 at The Wetland Centre for Wales, Llanelli, Carmarthenshire.
