tured among 1,222 bats of 10-11 species in the Gallinas Mountains) and ponderosa pine forests 
(fourth in relative abundance, with 57 captured among 447 bats of seven to eight species in the San 
Mateo Mountains) in New Mexico. However, reproduction in females was higher in the pinon- 
juniper woodlands (Chung-MacCoubrey, 2005). At higher elevations in the San Mateo Mountains 
of New Mexico (ponderosa pine or mixed Douglas fir-blue spruce forests) this species was the sec¬ 
ond most abundant bat captured in mist nets (506 individuals among 1,390 bats of 10-11 species) 
during 19 years of sampling over a 34-year period at a natural pool in a canyon floor, elevation 
2,573 meters (Geluso and Geluso, 2012). They ranked fourth in abundance (38 captures among 855 
individuals) among 16-17 species mist netted over ponds during 1970 at Nogal Canyon, Socorro 
County, New Mexico, in habitats described as pinyon-juniper, pine-oak woodlands, and mixed- 
conifer forest at 2,440 meters elevation (Black, 1974). Somewhat farther south, Jones (2016) doc¬ 
umented bats captured during surveys of various habitats in the Greater Gila region of Catron, 
Grant, and Sierra counties of New Mexico; long-legged myotis ranked eleventh in abundance, with 
seven captures among 282 individuals of 16-17 species and were primarily taken in ponderosa pine 
forest (Jones, 2016; including data from unpublished reports of others). A survey that took place at 
37 sites across several habitat types in much of New Mexico yielded 1,752 bats of 21 species with 
131 long-legged myotis, ranking third in relative abundance (Geluso, 2006, 2017). 
Texas : At Big Bend National Park in Texas, long-legged myotis were rare (six bats among 
4,807 captures of 18 species at 32 localities) during 1967-1971 and were taken only at higher-ele¬ 
vation habitats (Easterla, 1973). A subsequent survey during 1996-1998 that emphasized lower- 
elevation habitats did not result in any captures despite the documentation of 1,978 captures of 17 
other species (Higginbotham and Ammerman, 2002). 
Central Rocky Mountains and Western Great Plains: Colorado: Long-legged myotis were 
by far the most common species of bat captured in the pinon-juniper woodland and ponderosa pine 
forests of Mesa Verde National Park in southwestern Colorado (elevations 1,890 to 2,361 meters), 
with 643 bats captured among 1,996 individuals of 15 species netted over water (O’Shea et al., 
2011a). During an earlier study at Mesa Verde in 1989-1994, they were the second most abundant 
species taken in mist nets (57 bats among 189 individuals of 11 species; Chung-MacCoubrey and 
Bogan, 2003). They were also the most common species of bat found in forests sampled along the 
northern Front Range in Colorado (236 bats among 634 individuals of nine species), with nearly 
all (95%) captures of this species in forests above 2,000 meters (O’Shea et al., 2011b). However, 
they ranked fifth in relative abundance in surveys across elevations encompassing ponderosa pine 
and Douglas fir forests farther south in adjacent Boulder County, with 129 captures among 1,398 
bats of ten species, but with 58% of all captures involving two species of bats (big brown bats and 
little brown myotis) that commonly roost in buildings (Adams et al., 2003). These bats were rarely 
reported (two captures among 506 bats of seven species) in the urban or urbanizing corridor imme¬ 
diately east of the Colorado Front Range (O’Shea et al., 2011b) and in the region in and around 
Calgary, Alberta (three captures among 1,974 bats of eight species; Coleman and Barclay, 2012). 
Long-legged myotis were the most co mm on species (100 captures among 111 bats of four 
species) at 2,900 to 3,500 meters in spruce-fir forests of the subalpine zone in west-central Col¬ 
orado, where adult females (likely non-reproductive) dominated samples (Storz and Williams 
1996). Maternity colonies have been reported as high as 2,774 meters at abandoned mines in Col¬ 
orado (Navo et al., 2000). They ranked third most common (57 captures among 546 bats of 11 
species) over stock ponds during surveys in pinon-juniper woodland at about 2,100 meters eleva¬ 
tion in the Uintah Basin in Moffat County in northwestern Colorado during 1979-1981 (Freeman, 
1984). In western Colorado, this species ranked fourth in relative abundance of 16 species (88 
among 899 bats) captured at Colorado National Monument and the adjacent Mclnnis Canyons
