Cattle Egrets have become a regular summer visitor to the Wirral in the last two or three years, and last year they were confirmed as breeding at an RSPB reserve there. I have made several visits to see them, as they are not at all common and I always assume it may be my last chance to see them.
They are a smaller than the more common Little Egret, and do spend a lot of their time around livestock and cattle.
These pictures were taken last year, and although not great, are a good record of it in it's nesting environment. (Taken at some distance so as not to disturb the birds.)
