Found what must have been most of them this morning at 0800 at O18 on the map but I couldn't be sure I had counted 63 (I think I heard bellowing from the direction of Long Bottom as I was leaving).
They all seemed to be well and much more settled with people now. But I was chatting with a birder who was checking the nests of Woodlarks and Nightjars who told me that the cows had eaten all but one of the 40 Bee Orchids he had counted on his previous visit. They don't seem interested in eating the Spotted Orchids though (but they're happy to lie down among them!).
