Rick Derevan writes that this Black-headed Grosbeak is “trying to figure out if the plum is ripe enough to eat.” According to the Cornell Lab of Ornithology, fruit isn’t the only thing these birds feed on. Black-headed Grosbeaks also eat seeds, insects, spiders, snails and even monarch butterflies—which are toxic to most birds.
