Birdhouse and Bees

Birdhouse in my pear tree. The trees are in full bloom right now. It was 80 degrees yesterday and it is supposed to snow tonight! Woe is me.

Bees of all shapes and sizes were buzzing around the pears yesterday. Their little legs were covered in white pollen - so cute. The warm day kept them busy and their hum was very loud. Today, the high was 44 and there wasn't a bee around. Nada. Recently, I read that the cause of the worldwide bee colony collapse is thought to be the industrial conglomerate Bayer. Supposedly one of their herbicides has an ingredient in it that is toxic to bees. Wonder if it is also killing the bats?
