This is not a book award, but more of a body-of-work award, although, according to Jeffrey Gordon, President of the ABA, The Crossley ID Guide was “an important reason [Richard] received [the award].”
Here is a description of the award from the ABA website: “Given for excellence in publications pertaining to field ornithology. The award is given specifically for publications on the subjects of field identification and bird distribution in North America. It is given to either authors or artists. This award recognizes professional achievements in field ornithology literature.”
