Walking up the side of a wood on my boundary a couple of weeks ago, I was startled by a hen pheasant blasting off in front of me, about five feet ahead. She took off out of a fine clutch of eggs, so I've kept away from there since in case I disturbed her too much. I'm not sure how many chicks she'll rear though, since there are buzzards wheeling about and screeching all over that area. I think they roost in the wood, because they're always there. Another thing, I've seen a lot of broken shells which I think were from pheasant eggs, quite large pale green - in fact just like the ones in the nest... Certainly no expert on that, but I think they've been robbed by something of the winged sort.
