This is Mr Robin who's partner is sitting on eggs in the greenhouse at present.   I've kept the greenhouse doors wide open the last two days as the temperatures rose, but today hasn't been too bad as it's been grey and humid without the sun beating down.   Mr Robin is constantly in and out with his beak full of insects, so perhaps there might be fledglings already, but I won't disturb them by trying to get a peek at the nest.
