Neotropical forest soundscapes with call identifications for katydids

Insects are an integral part of terrestrial ecosystems, but while they are ubiquitous, they can be difficult to census. Passive acoustic recording can provide detailed information on the spatial and temporal distribution of sound producing insects. We placed recording devices in the forest canopy on Barro Colorado Island in Panamá and identified katydid calls in recordings to assess what species were present, in which seasons they were signaling, and how often they called. The focal recordings were collected at a height of 24 meters in two replicate sites, sampled three times per night across five months, spanning both wet and dry seasons. Katydid calls were commonly detected in recordings, but the call repetition rates of many species were quite low, consistent with findings from individual focal recordings. The recordings contained 6,789 calls with visible pulse structure. Of these, we identified 4,371 to species with the remainder representing calls that could not be identified to sp..., ,
