Some statistics for your information. This is the percentage of time males v females when the nest box is occupied. I’ve asked for it not to be copied as these unpublished data, which may end up being corrected. It’s clear that, when the box is occupied, almost half that time is when the female is simply standing (or lying) on the ledge. Diamond’s predecessor, Swift, may have been quite old and she was clearly lame toward the latter part of her residency and she spent many hours lying on or near the ledge.
