US SWAP National List IUCN Red List Canada Species at Risk Mexico Eastern Red Bat The eastern red bat has light gray-brown fur on the upper side of its body and more whitish fur on the under side, with an orange-red face. Females are more likely to exhibit paler coloring. This species prefers to live within more remote, forested areas. Males are more likely to occur in cooler regions, with females tending to occur in warmer, lowland areas. This bat will roost amongst the foliage of deciduous or occasionally evergreen trees. In winter, this species hibernates by burrowing into leaf litter and bunch grass. Their diet consists primarily of moths but other insects such as beetles and members of Hemiptera are also featured on the menu. Females commonly have more than a single pup (baby bat), twins or triplets, but can have liters of up to five pups.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Brazilian Free-tailed Bat Brazilian free-tailed bats are named for the long tails that extend beyond their uropatagium (membrane surrounding the tail). Like other species of the family Molossidae, Brazilian free-tailed bats have distinctive large, rounded ears that form a semicircle around the face and nearly meet on the forehead. They are a fast flying bat and have been clocked at speeds up to 60 mph. This species is know for its extremely large colonies; the largest, Bracken Cave, is home to more than 15 million individuals. Brazilian free-tailed bats commonly roost in caves, bridges, and buildings. They are generalist feeders, preying on moths, beetles, flies, and insects in the order Hemiptera. Females typically give birth to a single pup each summer. The average lifespan of Brazilian free-tailed bats is 8 years.

Found throughout Mexico and the southwestern United States, it occupies a large range of habitats including riparian woodlands, desert regions, and tropical forests. The western yellow bat roosts in trees and within dead palm fronds, well-camouflaged by its yellowish fur. This bat migrates south for the winter but does not hibernate. Beetles are the main food source of western yellow bats though they will eat other insects. Mothers usually rear two to four pups annually.

Status & Trends Measures of where North American bats occur, in what numbers, and how these metrics change over time. Photo credit: Jordi Segers NABat uses multiple lines of evidence to understand where, when and how bat populations change over time. Bats are challenging to monitor and not all survey types work well for all species. Additionally, different response types are more or less sensitive to observing changes in populations. Looking at multiple status variables informed by several data streams provides a more complete view into population status and trends.

METHODS & SAMPLE DESIGN NABat relies on a probabilistic, yet flexible sampling approach. Our protocols and guidance ensure data standards are integrated across the multiple lines of evidence that are employed to inform status and trends analyses of North American bats. Photo: Melissa McGraw The Protocol consistent yet flexible Bats have diverse and complex life histories and behaviors, making a 'one size fits all' approach to monitoring impractical. Our protocols were conscientiously designed with this in mind, providing clear but adaptable guidance for bat monitoring efforts in the U.S., Canada and Mexico. The Plan > The Master Sample a probabilistic sampling approach NABat monitoring follows a master sample approach in which North America is divided into a series of 10 x 10 km (100 km) grid cell frameworks. The generalized random-tessellation stratified (GRTS) survey design algorithm then assigns a spatially balanced and randomized ordering (GRTS order) to each cell within its respective framework. Grid cells are prioritized numerically; the lower the number, the higher the sampling priority. Cells can then be selected for monitoring following the GRTS order, ensuring both randomization and spatial balance. Monitoring within this standardized framework allows statistical inference to non-surveyed locations and ensures the validity of analyses at regional and range-wide scales using data collected by dozens of partners across the continent.

Threats to Bats Learn more about factors impacting the survival and health of North America's bats Photo Credit: National Park Service The Problem: North American bats are currently facing a range of significant threats that have led to alarming declines in various species. Key issues include diseases such as white-nose syndrome, collisions with wind turbines, and habitat loss and degradation. Understanding species distributions and abundance, as well as how these metrics change over time, is critical to assessing the viability of bat populations and identifying when populations are recovering. A Solution: The North American Bat Program effectively addresses the historical lack of information regarding bat species status and trends through coordinated, standardized, long-term data collection. The data collected as part of NAB will contribute to spatially explicit estimates of bat distributions and abundance, as well as track changes over time. information is vital for filling knowledge gaps and supports proactive management of bat populations. White-nose Syndrome White-nose syndrome (WNS) is a disease caused by an invasive, cold-growing fungus that affects hibernating bats . The fungus grows on bats’ skin, disturbing hibernation and resulting in dehydration, starvation, and often death. First documented in New York in 2006, WNS has since spread to numerous U.S. states and Canadian provinces, causing severe population declines in many bat species. Click on the button below to learn more or explore the WNS publications database . Learn more Wind Energy Current evidence suggest that collisions with spinning wind turbine blades may kill hundreds of thousands of bats each year in North America. Although it has been theorized that barotrauma, internal injuries caused by rapid changes in air pressure, may also contribute to bat fatalities at wind turbines, research shows this is exceedingly unlikely . Given that bats are long-lived and typically limited to 1 or 2 offspring per year, existing fatality rates may not be sustainable for some species . Recent studies indicate population-level declines are possible, particularly with the anticipated growth of wind energy development (see example wind energy future scenarios for the U.S. here ). As a result, significant investments have been made in search of solutions that minimize impacts to bats without impeding the continued deployment of wind energy. Learn more from this webinar recording or click below to explore literature on this topic. Learn more Habitat Loss & Degradation Forests and underground structures like caves and mines are critical bat habitat for roosting, foraging, and reproduction. The growing loss of these habitats, continues to cause substantial impacts on the abundance and diversity of bats at a global scale.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Southeastern Myotis The southeastern myotis is distinguishable from other Myotis species by its woolly, bi-colored fur (dark brown at the base with pale tips) and especially long toe hairs. Summer habitat includes hardwood and mixed forests, coastal areas, and a wide range of riparian habitat. Maternity colonies are often associated with caves, but have also been observed in hollow trees and man-made structures like bridges and culverts. In its southern range, the species remains active for much of the winter, but individuals in the northern range hibernate in some of the same structures used for summer roosts (e.g., caves). Females of this species typically give birth to twin pups. Diet consists primarily of mosquitoes, crane flies, and moths.
