US SWAP National List IUCN Red List Canada Species at Risk Mexico Mexican Long-nosed Bat The Mexican long-nosed bat is dark gray to brown with a long nose and distinctive nose leaf. The habitat of this species is desert scrub and includes vegetation such as agave, creosote, mesquite, and various cacti. They range from the southwestern US to central Mexico. The Mexican long-nosed bat roosts in caves, rock crevices, old tunnels, and mines. Its main food is nectar and its tongue can reach 3 inches into agave flowers to access nectar. This species is one of the main pollinators of agave plants including mezcal, tequila, and century plants. This species migratory activity mirrors the seasonal flowering of agave. Mothers give birth to 1 to 2 pups per year. It is estimated that this species population has declined by over 50% over the last 25 years. These bats typically live 10-12 years in the wild.

US SWAP National List IUCN Red List Canada Species at Risk Mexico Northern Long-eared Myotis The northern long-eared Myotis has light brown fur on its back with paler gray fur on its underside. The face, ears, and membranes are dark. This species' ears are long compared to other bats in the Myotis genus and feature a characteristically sharp and pointed tragus. In the summer, the northern long-eared Myotis can be found in its more northern range, preferring dense forest stands. Roosts are primarily located in trees and buildings, with maternity roosts often found beneath the exfoliating bark of dead trees or within tree cavities. Winter roosts are typically located in small caves or crevices, such as underground mines. Typically, this species roosts alone or in small groups (about 20-60 females to a maternity roost). Moths constitute the primary diet of this species. The fungal pathogen white-nose syndrome, has caused population declines of up to 99% at hibernation sites.

Back to Search ERROR WARNING: null value in column "" violates not-null constraint 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. 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: A recording name is unique to a project and can only be processed as part of one deployment. An entry of this recording name already exists HOW TO RESOLVE: Duplicate errors occur when the system encounters repeated survey records. This error typically occurs when duplicate records occur within an individual csv. Use conditional formatting on a unique identifier—such as 'Audio Recording Name' for acoustic surveys, or a concatenated set of fields (using CONCAT or TEXTJOIN) for other survey types—to highlight repeated rows, then delete or consolidate them. If duplicates persist despite removing and re-uploading affected data, contact the NABat Technical Outreach Team. ADDED EXPLANATION: The duplicate detection logic in the NABat database varies by survey type. For emergence count surveys, each unique combination of Site Name, Exit Identifier (if provided), Surveyor, and Species should appear in a single row—multiple rows from the same surveyor for the same combination are flagged as duplicates, whereas rows from different surveyors are averaged to produce the final count. Roost count surveys use different logic: counts are summed within each surveyor's report for a given site, section, and species, and if multiple surveyors report, their sums are averaged—so duplicates are not flagged in the same way. Beyond survey-type logic, duplicate errors can arise from re-uploading the same data in quick succession, inadvertently uploading the same survey under different file names, accidental copy/paste duplication within a file, or leftover data from older versions of the upload logic. When identifying duplicates within a file, Excel's Conditional Formatting (Home → Styles → Conditional Formatting → Highlight Cells → Duplicate Values) can highlight repeated values in a unique identifier column. For surveys lacking a single unique field, create a new column that concatenates key fields to form a composite identifier. When comparing across uploads, note the conflicting file's name and created date in the Partner Portal, download it, and review side-by-side with your current file to determine which version is more complete or accurate. In rare cases, the database may retain artifacts of previously deleted data that trigger duplicate errors on subsequent uploads—if you suspect this scenario after repeated removal and re-upload attempts, contact the NABat Technical Outreach Team to investigate.

Back to Search ERROR WARNING: There already exists an entry for this species, for this observer, for this emergence event HOW TO RESOLVE: Duplicate errors occur when the system encounters repeated survey records. First determine whether duplicates are within the current file or span multiple uploads. For within-file duplicates, use conditional formatting on a unique identifier—such as Audio Recording Name for acoustic surveys, or a concatenated set of fields (using CONCAT or TEXTJOIN) for other survey types—to highlight repeated rows, then delete or consolidate them. For emergence counts specifically, group data by 'Site Name', 'Exit Identifier', 'Surveyor', and 'Species', then sum counts into a single row. If duplicates span multiple uploads, locate the conflicting file in the Partner Portal's Surveys tab, download it from Project Files, and compare contents with your current file. Keep the most complete version and remove overlapping rows from the other, then re-upload. If duplicates persist despite removing and re-uploading affected data, contact the NABat Technical Outreach Team. ADDED EXPLANATION: Duplicate detection logic varies by survey type.

Back to Search ERROR WARNING: Audio Recording Time not within Start and End Times HOW TO RESOLVE: A survey window conflict occurs when a record's timestamp ('Audio Recording Time') falls outside the reported 'Survey Start Time' and 'Survey End Time'. For acoustic datasets, address errors based on the number of records affected. A few error rows can be removed or resolved through manual adjustments to the Audio Recording Time. If many records are affected, check for consistent time offsets or other systematic shifts, then resolve by batch-shifting times for uniform offsets, removing pre/post-survey recordings that fall outside the actual survey period, or extending the survey window to include legitimately captured records. ADDED EXPLANATION: To troubleshoot survey window conflicts, first check if timestamps align with known survey date(s) and times. If they do, detector misconfiguration is unlikely. If they differ, look for uniform shifts (e.g., in minutes, hours, or dates) that may have been caused by incorrect detector presets; these can be corrected by adjusting values in a spreadsheet or coding tool. Many applications let you add or subtract date/time values arithmetically. Note that detector datetime formats that include a "T" between date and time, or that include a time zone at the end (e.g., "-07.00") can make it difficult to arithmetically adjust timestamps in programs like Excel. If so, If so, use {Find/Replace} tools to swap the “T” for a space, and replace the time zone portion (e.g., “-07:00”) with a blank value, then re-format the column as a standard date/time. Records captured between detector recording-ON and survey start, or survey end and detector recording-OFF should be removed. Errored records resulting from inaccurate survey start/end times can be resolved by extending the listed survey start/end times to accommodate documented recording times.
