The Association of Field Ornithologists (AFO) is an American ornithological society, with a strong focus on field studies and banding, priding itself as serving as a bridge between professional and amateur ornithologists. It was founded in 1922 as the New England Bird Banding Association, then becoming the Northeastern Bird-Banding Association, before expanding its geographical scope and acquiring its current name. It publishes a twice-yearly newsletter, AFO Afield, as well as the quarterly Journal of Field Ornithology. The AFO is a member of the Ornithological Council.
