The first bumblebee of the season

It's a beautiful sunny day here in Oslo, and the crocuses in the yard are in full bloom, loving the sunshine. The first bumblebee of the season also made its appearance (the first one I've seen at least), in love with the crocuses. It made its way from flower to flower, landing on each of them and then rolling around in the pollen sitting on the top of the filament, quite a happy bee. One cannot take the bees for granted anymore, due to colony collapse disorder and bee deaths. So I was glad to see that this bumblebee was healthy and functioning. A bumblebee watching site on Twitter contacted me to tell me that this is Bombus hypnorum, a tree bumblebee, also called a new garden bumblebee. These bumblebees often live near human settlements, like to build their nests above ground and often inhabit bird boxes.
