The American Ornithological Society (AOS) Loye and Alden Miller Research Award is given for lifetime achievement in ornithological research. Loye Holmes Miller and his son, Alden, left a remarkable legacy to the field of ornithology and to the Cooper Ornithological Society (COS). Together they sponsored 30 Ph.D. students, 28 in avian biology, and their students went on to train in turn a total of 166 scientists. Alden also made contributions to the COS and to ornithology as a long-standing editor of The Condor. This year, AOS is pleased to honor A. Townsend Peterson as the recipient of the Loye and Alden Miller Research Award.
