Abstract

Songs of four individuals of Empidonax traillii were recorded and analyzed on an audio-spectrograph. The four spectrograms, two of the fitz-beu type and two of the fee-bee-o type are presented. The spectrograms show great similarity in the songs of different birds singing the same song type and conspicuous differences in the two song types. The actual recordings on tape are available from Cornell for further study, and these are, or will presently be, published on phonograph discs.
