It's not every day we see this strutting about on the bathroom roof as though it owns the place. We think it must have been looking for somewhere to roost and got lost. Apparently there has been a peahen in Goldhanger for about 2 months now - so the one Stephen saw in the street a couple of weeks ago wasn't imagination after all!
The cat might have needed long-term therapy had she seen it, but I don't think she had. In any case she stayed indoors well out of harm's way. The peahen would have probably come off better in any altercation between them anyway.
