    We present a new method of summarizing Peter Pyle's (1997) ageing and sexing guide into a tabular format that has proven to be extremely useful for both novice and experienced banders. This format allows quick and accurate assessment by a bander to distinguish species, age, and sex criteria. Rapid and accurate processing are essential to the health of birds captured and this effort assists in achieving this goal. We give examples of the "Tabular Pyle" for the Hermit Thrush and the Yellow Warbler, as well as a comparison of all Catharus thrushes.
