He married Mary Norton and they had two sons. His second marriage, which lasted 14 years, was to Christina. He married a third time, to Karen.
He received his Ph.D. from California Western University in 1975. His thesis became the first edition of his Birds of the World, A Check List (now in its sixth edition). Clements was mostly finished with the sixth edition at the time of his death, and responsibility for the series was taken up by the Cornell Laboratory of Ornithology by arrangement with Clements's widow, Karen. The Ornithology Lab finished the sixth edition, maintains corrections and updates for it, and plans to publish future editions.
A bird, the Iquitos Gnatcatcher, Polioptila clementsi, is named after him.
