If you can imagine the whoosh that we heard as we were being warned not to get too close to the nest. We were quick. After we left the garden, they both came to check out the nest to make sure that we hadn't done any harm.
So, I think because we were that close and they know we did no harm, he wasn't as skittish when I tried to get closer to him.
Isn't he handsome in his blue coat and rust vest!!!
