Well, I can?t say I associate such daft behaviour with pheasants (and there are a lot of them around our part of the world).
For another take on pheasant psychology consider this little anecdote: several months ago (pre-lockdown) Miranda and I were out somewhere in the Dales when we came across two pheasants at the side of the road, one of which was dead, having been killed by a vehicle, I suppose; I can?t remember whether it was the male or the female. Anyway, the still-alive one was walking round and round the body, frequently going in close to it to nuzzle it and try to get it to stand up, I guess. It was obvious to us that the live bird was grieving for its mate.
