Spur-winged Goose Foraging
A Spur-winged Goose grazes in a field of spring flowers. Sometimes it is difficult to understand why, in the course of human history, some geese and ducks have been domesticated and others haven't. However, with regards to the Spur-winged Goose, this may be easier to guess. Some of these geese eat toxic bugs known as blister beetles. The toxin doesn't affect the geese but is stored in their tissues and can be poisonous to people that eat them.
