Residents of Watchet, England contacted the Environment Agency after finding their cars and garden furniture covered in a yellow liquid. Biologists examined samples and found that the yellow dots were bee droppings containing mainly pollen grains. An Agency spokesman Alan Trevelyan said: "It is natural behavior for bees leaving the hive after they've digested pollen on 'cleansing flights"." I hadn't thought of it, but I guess bees have to crap too!
