Degree of Threat: Very high - high
Comments: This bat is vulnerable to habitat loss (in urban and forested areas), habitat alteration (removal of old trees with cavities, or buildings with spaces suitable for roosting), and pesticide spraying for mosquitoes. The last may be responsible for the species' decline in the Miami area, as roosting sites are still abundant. Severe hurricanes may cause loss of older trees with roosting cavities. Hurricane Andrew, an intense Category 5 hurricane that struck southeastern Florida in 1992, may have had a significant impact upon the already low population of bonneted bats (Timm and Genoways 2004).
