Its long fur varies from blond to dark brown, and distinguishing characteristics include a keeled calcar and extremely small feet. It ranges as far north as southeast Alaska and as far south as Guatemala, inhabiting deserts, grasslands, montane forests, and humid coastal forests. California myotis have been observed in a variety of roosts, including rock and tree crevices, bridges, caves, mines, buildings, shrubs, and even on the ground. Caves and buildings serve as hibernacula. This species feeds mostly on moths and flies but will also eat beetles, caddisflies, termites, and spiders. Females typically give birth to one pup at a time.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Florida bonneted bat The Florida bonneted bat has short fur in colors ranging from black to reddish-brown. Its round ears meet at a single point in the middle of the forehead. This species lives in semitropical forests including mangroves and is only found in small regions of coastal Florida. It roosts in trees, buildings, and crevices. This endangered species is threatened by dwindling habitat lost to human development and hurricanes; populations also suffer indirect poisoning by pesticides. Mothers rear an individual pup during summer but may be polyestrous, birthing a second pup in midwinter.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Long-legged Myotis The long-legged Myotis is one of the larger species in the Myotis genus. Its fur is a medium gray-brown on the dorsal side, with whiter fur on the underside. The ears, face, and membranes are dark. Ears are large and pointed. True to its name, this species has relatively long legs and comparatively small feet. The long-legged Myotis relies on wooded habitats, such as pinon-juniper and coniferous forests, at elevations of 4,000 to 9,000 feet. Roosting sites include large caves and abandoned mines, with maternity roosts commonly located beneath the bark of and inside cavities of trees. Long-legged Myotis also roost in rock crevices, among cliffs, and inside buildings. Maternity roosts of several thousand individuals have been observed. Moths are a common source of prey. Within a single foraging period, lasting less than an hour, individuals can catch all of the prey required for a night. Common foraging habitat includes forest clearings and bodies of water.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Little Brown Bat The little brown Myotis' fur ranges from brown to yellowish to gray-brown. In its western range, the little brown Myotis prefers mountainous habitat and riparian areas in a variety of forest types. It can often be found roosting in man-made structures such as buildings, attics, and bat boxes in towns and open, arid areas. Little brown Myotis will also roost beneath the bark of dead trees, inside tree cavities, under rocks, and in woodpiles. The little brown Myotis consumes a wide variety of aquatic insects, from midges and mayflies to moths and beetles. Lactating females may consume up to half their body weight in insects during a single night while nursing pups. During winter, the little brown Myotis hibernates in caves and abandoned mines, aggregating in colonies that often number tens of thousands of individuals. This species is particularly susceptible to the fungal pathogen white-nose syndrome, which has caused populations to decline drastically.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Evening bat Evening bats can sometimes be mistaken for juvenile big brown bats due to their smaller size but otherwise similar appearance, particularly the broad muzzle and rounded ears. The species' fur is dark brown at the base with grayish-brown tips and is typically lighter on the belly. They live in deciduous forests throughout the Southeast and Midwest, roosting in trees and buildings. Evening bats migrate south in the winter, and one banded individual was sighted 340 miles from it's summer capture location. The species' diet consists primarily of beetles but can also include flying ants, stink bugs, and moths. Females typically have twins. Evening bats have a relatively short lifespan of ~4-6 years.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Hoary Bat The hoary bat is a stunning bat with dark gray and brown fur, covered in white, frost-like tips. Hoary bats are one of the largest in America, with females being larger than males. This species is more likely to avoid roosting in human made structures, preferring wooded areas where it can hang alone, high up in the trees and along forest borders. When foraging for a meal, the hoary bat prefers to dine primarily on moths. Wind turbines have posed a significant threat to this species, with hoary bats suffering mortality due to impact with turbine blades.

Back to Search ERROR WARNING: is an invalid float HOW TO RESOLVE: Use the template's second header row to view data type requirements and replace erroneous data in flagged field based on the field's listed requirements. Non-numeric entries are typically the source of this error. Example: The "Latitude" field in the stationary acoustic template accepts float data. Non-numeric entries, e.g. a string value, or numbers with incorrect characters like a comma. If the "|" pipe symbol at the start of header row gets accidentally removed, those rows will no longer be treated as headers and instead will be read in as data rows. This results in categorical or data type errors like, " is an invalid float". Simply make sure a pipe symbol "|" is included at the start of each header row and re-upload your csv to the Partner Portal. ADDED EXPLANATION: Each field in the template requires a particular data type (text, integer, decimal, date-time, or true/false) or a controlled categorical response. Values that don't match these requirements will be rejected. In a spreadsheet, adjust cell formats or use find/replace to convert values—for example, changing numbers stored as text into actual numbers, converting decimals to integers, or trimming time-zone suffixes from date-time strings.
