I did my annual survey of nesting HM in the Bay area this week. Preliminary results indicate a big drop in numbers, with one former colony having no nests at all.. However, I saw one pair just starting to build a nest in Windsor Quay and a second half-built nest looked like it was this years, although I didn’t see the adults. Are birds still arriving? Or maybe they lost a first nest. And are numbers down generally?
My survey covers Adventurers Quay, Penarth Marina, Grangemoor Court and Windsor Quay. If anyone knows of other nesting HM in the Bay area, please contact me or reply to this post.
