The hummer was going around the geraniums etc, in the GHouse for the winter, we open the door if its a decent day. I went in and he was looking for a way out so I just picked him up and took him outside and let him go, are they small.
Thank goodness you spotted him. I've had Blue tits, robins and bees getting into the greenhouse and they batter themselves off the glass. Sometimes it's not easy catching them as they get into such a panic.
