Great Crested Grebe 3 - sorry about the jerky nature of this clip, I was stood on shifting sands, but I like it as it shows the grebe raising its "great crest"Little Egret 6
Ringed Plover 6 (one flock)

Herring Gull 1,000+ this clip shows some of one of the two main groups, they are just moving to the emerging outer skear.
They are still feeding on the seed mussels, but life isn't quite as easy as it was. This is how the seed mussels were when the gulls started feeding on them. This shot is the 13th May (note my hand still in winter plumage).
|Note how all the seed mussels are similar sized and small|
This is how they look today, surprisingly this is the first day out here this year that I haven't felt the need for my mitts.
|They are now variable in size, the larger ones to the right of my finger are the remaining earlier seed |
mussels the smaller ones are newer seed mussels that have filled the gaps over the intervening weeks
This has two effects for the Herring Gulls, first the larger seed mussels are now too robust to be crushed open in their gizzard. Meanwhile the stronger threads the larger mussels use to anchor their position, also help to anchor the smaller mussels making it more difficult to detach them. On the plus side for the gulls, even the smaller mussels are larger than the earlier seed mussels and will contain a lot more protein.
These were today's gulls teasing out their meals.
