Field Playback Of Male Display Attracts Females In Lek Breeding Sage Grouse, Robert M. Gibson
School of Biological Sciences: Faculty Publications
Recent correlational studies of lekking sage grouse suggest that male vocal display attracts females. To test this hypothesis further, the natural displays of a territorial male were supplemented with the tape-recorded display of another reproductively successful individual. Significantly, more females approached the speaker's location on days when the recording was played, and also on nonplayback days immediately following a playback, than on other nonplayback days. Analysis of male displays indicated that females were responding to the playback itself rather than to changes in male behavior. The "after-response" following a playback suggests that some females present during a playback remembered its …

Papers in Herpetology
On 13 February 1988. at 1600 h. a captive-bred (hatched July 1985) male Elaphe bairdi (TL.136.9 cm, SVL .. 89.54 cm). maintained in a 50.5 x 25 x 30 cm terrerium was accidently splashed with water. As beads of water on the snake's head rolled down to the upper labial sceles. swallowing was observed. The water on the labial scales was drawn Into the mouth while It was closed. This behavior lasted 42 sec. This behavior was repeated 23 out of 24 trials conducted during the next 24 days. The duration of swallowing wes 9-62 sec (avg 35.8, N = …
