During 2007–2010, we captured the western red bat (Lasiurus blossevillii) and Arizona myotis (Myotis occultus) in riparian-restoration areas along the lower Colorado River. Previously, the western red bat had not been reported along the lower Colorado River and the Arizona myotis was presumed to be extirpated from that area.

Durante los años 2007–2010, capturamos el murciélago rojo occidental (Lasiurus blossevillii) y el murciélago de Arizona (Myotis occultus) en sitios de restauración riparia ubicados a lo largo del río Colorado. El murciélago rojo occidental no ha sido registrado en el tramo inferior del río Colorado y el murciélago de Arizona se presumía ausente del área.
