Comments for all niche requirement fields:
Code Comment
00250:Forage over water *01*.
00280:Caves are preferred roosting sites *03*, especially in the northern part of the range *05*. Are usually found in caves that contain water *01*.
00490:Roost in hollow trees *01,05*. Wintering sites include hollow trees and crevices in bark in florida *01*.
00690:Roosting sites include buildings and other protected shelters *03,01,05*. Roosts in buildings are found more often in the southern part of the range *05*. Sometimes winter under bridges and in boathouses, drainpipes, culverts, and buildings *01*. Use bridges as day roosts *010*.
99999:In winter, leave maternity caves and take up residence in small groups at outdoor sites in the south *03*. Southeastern bats are found in the company of free-tailed bats (tadarida brasiliensis)in buildings, or with gray bats (myotis grisescens) in caves *01*.

Comments about Life History:
Code Comment
007:90% of pregnant females bear twins in late April or mid-May *03*.
030:Clusters of young often are separate from adult females during the day *03*.
006:Forage close to water's surface, feeding on a variety of insects *03*
099:Nursery colonies begin forming in March in caves where water is plentiful *05*. Few males are in the nursery colonies. Most males roost elsewhere, alone, or in small bachelor colonies *01*.
018:At 3 weeks of age the young bats are able to maintain themselves *01*. Young can fly when 5-6 weeks old *03*.
035:Southeastern bats are prey for small carnivores, owls, corn snakes, rat snakes, opossums *01,03,05*. Cockroaches in bat caves eat the very small young that fall to the floor *01*. High mortality of young in maternity caves is occurs because young that drop to the floor are seldom retrieved *01*. Parasites include: streblid fly (trichobius major), nycteribIId fly (basilia boardmani), chiggers (euschoengastia pipistrelli), and mites (olabidocarpus whitakeri) *01*. Humans are the major threat to the species, destructing roosting sites and killing bats *03*.

Adverse Management Practices:

Adverse Management References:

Comments on Management: Human destruction of bats' roosting sites and killing of these bats are a major threat to the species *03*. Using fences instead of cave gates to control access to caves was recommended by a FL study, where a steel bar gate apparently altered air flow to the bat roost and obstructed the natural flight path. When the gate was replaced with a fence near the cave entrance, the number of bats using the cave entrance increased significantly *09*
