The advertisement calls of male anurans (frogs and toads) are loud and conspicuous signals, and the sound generated by breeding aggregations of males propagates over long distances. As a by-product of communication within an aggregation, the sounds of a frog chorus constitute a form of inadvertent social information that provides potential long-distance cues about the location and timing of breeding. We investigated whether female American toads ( Bufo americanus Holbrook, 1836) and Cope’s gray treefrogs ( Hyla chrysoscelis Cope, 1880) use the sounds of a chorus to locate breeding aggregations in the absence of other sensory cues. Females of both species approached speakers broadcasting recordings of a chorus made from distances of 0, 20, and 40 m, but not from distances of 80 and 160 m. Female toads also exhibited phonotaxis to a completely artificial chorus sound, but female gray treefrogs did not. We found little evidence to suggest that female American toads and Cope’s gray treefrogs differed substantially in their responses to natural chorus sounds despite potential differences in the predictability and duration of breeding seasons in these two species. Our results suggest that the inadvertent social information of a chorus could be used over short distances to locate breeding aggregations.

Wildlife surveys have a critical role in conservation efforts and the collection of life history data. For anuran amphibians these surveys often focus on calling males. In order to further our understanding of anuran ecology, we used automated recording systems to monitor the calling activities of the anuran communities at two beaver-formed lakes and one cattle pond in southeastern Oklahoma. We documented 14 anuran species between 5 February and 28 April 2012. Temperature had a significant effect on the calling patterns of Eastern Narrow-mouthed Toads (Gastrophryne carolinensis), Green Treefrogs (Hyla cinerea), Gray Treefrogs (Hyla versicolor), Southern Crawfish Frogs (Lithobates areolatus areolatus), and Cajun Chorus Frogs (Pseudacris fouquettei). Temperature did not have a significant effect on the calling patterns of Dwarf American Toads (Anaxyrus americanus charlesmithi), American Bullfrogs (Lithobates catesbeianus), or Green Frogs (Lithobates clamitans). There was not a significant relationship between rainfall and calling for L. a. areolatus. The presence of several of these species, including L. a. areolatus and Hurter’s Spadefoots (Scaphiopus hurterii) was unusual because these anurans typically breed in ephemeral, fishless pools, but the beaver lakes are permanent and sustain populations of carnivorous fishes.
