Loss of Human-made Roosts (Buildings and Bridges)

Yuma myotis (Myotis yumanensis)
Family:Vespertilionidae

This species is often associated with buildings (see Kunz and Reynolds 2003), but in CO its distribution does not overlap with urban areas significantly and is most often found in southern and western parts of the state in semiarid canyonlands and mesas (Fitzgerald et al. 1994).  Night roosts and maternity roosts have been documented in bridges in Colorado.
