Degree Of Call Synchrony During Interactions Between Male Snowy Tree Crickets, James W. Popp

Field Station Bulletins

Call synchrony has been reported for the snowy tree cricket (Oecanthus fultoni), but the degree to which it occurs in natural interactions has not been previously investigated. I recorded acoustic interactions among ten pairs of male snowy tree crickets to determine the degree to which call synchrony occurs. High levels of call synchrony (percent of calls that temporally overlapped another call) were found in all pairs, but in only half of the pairs was synchrony greater than expected by chance. Males differed considerably in their tendency to temporally overlap the calls of their neighbors. There was minimal frequency overlap of …
