Before he became curator of birds at the North Carolina State Museum of Natural Sciences in Raleigh he worked as research associate at the Louisiana State University in Baton Rouge from 1980 to 2005.
In 1975 Pratt was one of the last scientists who were able to photograph the possible extinct ʻōʻū and one of several scientists to record the song of the extinct Kaua'i o'o.
Pratt wrote important revisions within the genus ''Zosterops'' and the subfamily Drepanidinae. In 1987 he split the bridled white-eye into the three distinct species ''Zosterops conspicillatus'', ''Zosterops semperi'', and ''Zosterops hypolais''. In 1979 he renamed ''Hemignathus wilsoni'' into ''Hemignathus munroi''. In 1989 he moved the Kauai amakihi from the genus ''Himatione'' to the genus ''Hemignathus''. In 2009 he suggested the new created genus ''Manucerthia'' for the Hawaiʻi creeper.
Besides his scientific work Pratt is also a musician. He plays autoharp and won the Walnut Valley Festival International Autoharp Championship in 2006. In 2012, he published his first record ''You Can't Play That on the Autoharp!'' Provided by Wikipedia
