two gulls with white wings

I had two white winged gulls today. One of which got the pulse really racing as I was visiting the Scotia to set up the bird boxes. It flew past me and all I got on it was a gleaming white pair of wings. When I followed it round the corner I was disappointed to be confronted by this monstrosity - an all white herring gull...

Apologies for the quality of the video - I only had my phone with me.



Later in the day though this little beaut flew past me and the monstrosity was forgiven. I've now seen lesser black-back, mediterranean and Iceland gulls on patch before I've seen kittiwake...
