Semiarid to arid areas, including xeric shrublands, palm groves, riparian woodlands, savannas, pastures, and croplands at elevations of 25-2400 m (more often at intermediate elevations). The Western Yellow Bat is often captured over water (e.g. streams, ponds, stock tanks, and rivers) and in open areas, canyons, and riparian areas.	The Western Yellow Bat has been recorded flying slowly and steady at 9-23 m aboveground and rapidly along arroyos. Feces contained species of Coleoptera , Diptera , Hemiptera , Hymenoptera, Homoptera , Lepidoptera , and Orthoptera .	Pregnant Western Yellow Bats usually bear two embryos and were captured from early May to mid-July, lactating females from late June to late July, and young from mid-July to September.	The Western Yellow Bat is crepuscular/nocturnal. Individuals were observed flying before dusk and captured during the first five hours of dark. In winter, it can reduce activity, suggesting periods of torpor. Roosting sites are mainly found in dead-leaf skirts of palm trees but also hackberry, sycamore, cottonwood, and vines. Roosting sites have been found 2- 2 m aboveground and 4 m above a road. Echolocation calls are c.6-9-2 milliseconds, with narrowband and single harmonic, and sweep from 52-68 kHz to 26-30 kHz.	The Western Yellow Bat is usually solitary, but small groups can be found. It was observed only during autumn in northeastern parts of its distribution, suggesting southward seasonal migration. In northern parts ofits distribution, some individuals are present throughout the year.	Classified as Least Concern on The IUCN Red List. The Western Yellow Bat is widespread, presumably has a large population, and occurs in several protected areas. Major threats are use of pesticides, fires, and trimming of palm trees.	Aguilar et al.

Often considered a subspecies of ega .	20000000	Lasiurus xanthinus	Least Concern		2017	2016-08-29 00:00:00 UTC	3.1	English	This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.	This species occupies a range of habitats of extremely arid areas to dry areas. It inhabits savannas, secluded woodlands, regions dominated by pasture or croplands, and even tolerates residential areas. It is insectivorous. It often roosts in trees, where it generally hangs from the midrib of a leaf using its hind claws and possibly its thumbs. Western yellow bats are thought to be noncolonial. Individuals usually roost in trees, hanging from the underside of a leaf. Where their range overlaps with that of native desert fan palms (Washingtonia filifera ), western yellow bats appear to select those palms (as well as Yucca species and other palm species) for roosting (Higginbotham et al. 2000), roosting individually or in small groups in palm tree skirts (O’Farrell et al. 2004). ;Mating probably occurs in autumn, with usually two babies are born in June ;(Wilson and Ruff 1999). ;The presence of up to four embryos suggests that size of litter may vary from two to four.	Probably one of the primary threats in the U.S., however, is the cosmetic trimming of palm fronds. The use of pesticides in date palm and other orchards may also constitute a threat to both roosting bats and the insects upon which they forage. Domestic cats, whether pets or feral, may be a significant source of predation, as they are for many lizards, songbirds, and rodents. Few threats for the survival for this bat can be reported.	It is a common species (Wilson and Ruff 1999). Some populations may be migratory, although some individuals appear to be present year-round, even in the northern most portion of the range. Western yellow bats probably do not hibernate; activity has been observed year round in both the southern and northern portions of the range. Capture sites are often associated with water features (e.g. stock tanks, ponds, streams, and rivers) in open grassy areas and scrub, as well as canyon and riparian situations. Neither the distribution nor the roosting habitat preferences of western yellow bats are understood well enough (Ortiz and Barrows 2014).	Stable	This species occurs in south California, Arizona, and New Mexico south to Baja California, west and central Mexico (Simmons 2005).		Terrestrial	It occurs in several protected areas, but desert populations may not be completely covered by these. It is necessary to avoid indirect habitat destruction, related to extensive use of pesticides, and fires near residential or camping areas.	Nearctic|Neotropical		FALSE	FALSE	Global	Simmons, N.
