Its fur ranges from grayish to chestnut, with dull-lead colored fur at the base of the hairs and pinkish-cinnamon fur underneath the body. The Indiana Myotis diet includes a variety of aerial insects. During summer, the Indiana Myotis roosts beneath the exfoliating bark of dead trees, commonly known as snags. During winter, the species prefers to hibernate in cold sites, often limestone caves containing pools of water. The Indiana Myotis was one of the first bat species to be listed as endangered by the U.S. Fish and Wildlife Service. Despite measures to protect the species' winter hibernacula, populations continue to decline, due partly to its susceptibility to the fungal disease white-nose syndrome, which impacts winter populations, as well as threats like pesticide use and deforestation which limit suitable summer habitat.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Big Brown Bat Big brown bats are medium brown in color, with darker facial features and ears. Their small ears and eyes sit upon a blunt face. This bat can be seen in urban and suburban environments of mixed agricultural use. As generalists, the species can be at home among timberline meadows to lowland deserts, and abundant in deciduous forest areas. Big brown bats will roost in artificial structures, including buildings, bridges, and bat houses. When selecting for hibernation roosts, this species can tolerate hibernating in areas that experience very cold temperatures. Big brown bats have a preference for munching on beetles but will eat a variety of insects. Females can consume up to their body weight in insects in a single night. In the west half of this species' range, females have been found to produce a single pup (baby bat), whereas twins are more frequent in the east.

Other distinguishing features include a long, pointed tragus and a short snout with pronounced lumps on either side. Its pelage is variable, with dorsal fur ranging from gray to reddish- or blackish-brown; and gray ventral fur showing brown or buff tips. It is a wide-ranging species, found from southern Canada to southern Mexico, occupying diverse habitats including coniferous forests, oak-hickory forests, and grasslands. Townsend’s big-eared bats typically roost in cliffs, caves, and rock ledges, hibernating in areas with substantial airflow. The species feeds mostly on moths but occasionally preys on other small insects. Females produce a single pup per reproductive cycle. The oldest recaptured Townsend’s big-eared bat was 21 years old. Townsend’s big-eared bats are one of a handful of low-intensity echolocation species colloquially referred to as "whispering bats." Two subspecies of Townsend's big-eared bat, the Ozark big-eared bat and the Virginia big-eared bat, are on the US federally endangered list.

Back to Search ERROR WARNING: Unable to distrubte transect points HOW TO RESOLVE: Ensure each row has a valid location combination: 'GRTS Cell Id' alone, 'GRTS Cell Id' with 'Quadrant', or 'Latitude'/'Longitude'. Verify longitudes are negative and lat/long values aren't swapped. If both 'GRTS Cell Id' and coordinates are present but conflict, remove whichever you trust less—delete the 'GRTS Cell Id' value (keeping the column) if you trust coordinates, or omit lat/long to let the system match on cell ID and site name. Ensure site names are unique to prevent ambiguity. For repeat visits to established sites, verify coordinates remain consistent—new coordinates within 55m of an existing site are ignored, coordinates 55–100m away create a new map point but maintain site association, but coordinates exceeding 100m generate an entirely new site record, breaking data continuity and preventing trend analyses. Mobile transect surveys operate under different logic that matches primarily on unique Site Name values; see "ADDED EXPLANATION" for details. ADDED EXPLANATION: NABat requires at least a 'GRTS Cell Id' to assign surveys to a 10×10 km grid cell, but recommends providing additional granularity via 'Quadrant' or 'Latitude'/'Longitude' when possible. Location errors occur when this information is missing, ambiguous, or internally conflicting. Ambiguity commonly arises when generic site names (e.g., "Bridge 1" or "Cave") are reused across multiple locations, or when provided coordinates fall outside the boundaries of the stated GRTS cell. For large datasets, load coordinates into GIS or mapping tools to verify placements and catch systematic issues such as swapped lat/long columns or missing negative signs. To avoid unintentional site splits when revisiting established sites, verify coordinates match prior uploads or omit coordinates entirely to let the system match on Site Name alone. Mobile transect surveys can match solely on a unique 'Site Name' value, bypassing some ambiguity checks applied to other survey types. It is recommended that users draw a line object representing their route on the project map, named to exactly match the Site Name value(s) in the upload file. The portal can then estimate missing lat/long coordinates by combining route geometry with elapsed time during the survey. Without a defined line object, surveys traversing multiple GRTS cells with missing coordinates cannot be processed—users must estimate coordinates themselves or provide the 'GRTS Cell Id' for each record. Surveys occurring entirely within a single cell should still have their route drawn; however, users preferring coarser resolution can provide only the 'GRTS Cell Id'.

Back to Search ERROR WARNING: FOREACH expression must not be null HOW TO RESOLVE: Enter missing required data based on the template's header rows—the third row indicates required status by field, and the second row lists data type restrictions. Ensure each record includes values for all required fields before re-uploading. Example: The "Auto Id" field in the acoustic templates must include one of the controlled categorical responses listed in the second header row. An entry for this field is 'REQUIRED' for successful data upload. ADDED EXPLANATION: Surveys must include key fields that answer the "where, what, when, and who" questions: either a GRTS Cell ID or latitude/longitude to locate the survey, a Site Name to describe the place, survey start and end times, and the names of surveyors. Each survey type may also require a few additional fields. If required columns are missing entirely, the upload wizard will block the file. If required columns are present but individual rows lack values, those rows will be flagged while the rest of the file can load. Use the template's informational header rows to identify which fields are required and ensure each data entry row contains values for these fields before uploading.

Back to Search ERROR WARNING: is an invalid boolean 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. Adjust cell formats or use find/replace to convert values to the correct type. Example: The "Microphone Weather Proofing" field in the stationary acoustic template allows for only "True" or "False" entries. If any other entry is included for this field, the "invalid boolean" warning will appear. 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 boolean". 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.
