Coastal ring-billed gulls often head inland and south during the winter, and some ring-billed gulls live their entire lives inland, exchanging the salty sea for rural farm fields or urban parking lots with dumpsters. Many ring-billed gulls nest inland near freshwater. Ring-billed gulls are named for the prominent black ring around the bills of breeding adults, like this one. The yellow eye also identifies this one as a mature gull. Seagulls can and will eat almost anything, from fish, insects, and rodents, to fast food scraps procured in a dumpster diving expedition.
