I've never seen a bird eat a bee or a butterfly. The little Anole Lizards are a different story though; I quite often see them stalking and grabbing butterflies and moths for a quick meal!
Does anyone know if bees sting birds? I've been wondering about that lately as our Bottlebrush tree is in full bloom and the bees have been all over it for the past few weeks. I took this picture last Friday, a Cardinal perched in the tree with his eyes closed. It was a chilly morning and he seemed to be warming up in the sun but I wondered if he had his eyes closed to keep the bees from stinging?
