The Yellow-breasted Chat, Icteria virens, is a member of the wood-warbler family, Parulidae, and exists as eastern I. v. virens and western I. v. auricollis subspecies. It is the only wood-warbler known to sing diurnally and nocturnally. One objective was to determine whether the eastern and western subspecies produce songs that differ acoustically; another was to determine whether a western population of Chats in Nebraska produces songs that differ acoustically at dawn and at night. Properties measured were maximum frequency, maximum power, notes/second, singing rate, and % time singing. In addition, the inter-song interval and % whistle notes were measured in dawn/night song. Recordings were obtained from Borror and Cornell Laboratories; ...
