Bird Songs in Slow Motion

New York's Hylochiclid Thrushes These four birds (Wood Thrush, Hermit Thrush, Swainson's Thrush, Veery) are the best North American singers and among the finest in the world. For an overview, here are four sonographed records, each with a slow-motion (half-speed, half-pitch) replay. More detailed individual listings follow. Sonograms are linear in frequency, 0-5512 Hz. except for the Wood Thrush which is 0-11025 Hz. Note that the Wood Thrush record is also about 3 times as long as the others. Sonograms and half-speed records were prepared using Martin Hairer's Amadeus software for Macintosh computers.
