Audio record will be included. Unusually high elevation for this species, was calling from the swamp next to the Ark Lodge waterhole at 16:44. JBradley points to a number of unusual records from this location, he believes the site acts as a trap for migrating birds hemmed in by high elevations and drawn to floodlights. Audio is filtered from 200-500 hz, taken on a phone so quality is low and noisy, but the call can still be discerned.
