Warm up sounds of Neoxabea cerrojesusensis found on Cerrojesusensis Mountain in Nicaragua. [Note: Video will not play with Microsoft Edge.]

This adult male Neoxabea bipunctata is warming up in early evening.  This video allows one to see what part of the wings are involved with sound production.  One wing holds the file with tiny 'teeth' projections and rubs against the the other wing which holds a scraper - producing the pulses.  After warming up, his wings will move much more rapidly and his song will be long trills.
