140P6322Q0049 Contractor Questions – Revised
1. Question: How many nights were monitored?
Response: Data was collected from 8 stationary points for 4 consecutive nights. Additional mobile transect data was collected for 1 night for approximately 1 hour. Total of 9 nights.
Follow-Up Question: By my count, that is either 33 detector-nights or 5 individual nights, depending on how things are tallied. Can you explain how a total of 9 nights were calculated based on this information?
Follow-Up Answer: Yes 9 nights total for all 8 stationary points and 1 mobile route is technically 33 total "detector" nights.
2. Question: Total number of files collected?
Response: Data is still be collected at this time but on average 8,200 files are collected each night of survey. Last year a total of 8,240 files were labeled by BCID and 580 bat calls were analyzed visually. Eleven total species/species groups of bats were recorded to include: Big brown bat, silver-haired bat, eastern red bat, hoary bat, gray bat, little brown bat, northern long-eared bat, Indiana bat, Evening bat, Tricolored bat, and Eastern small-footed bat.
Follow-Up Question: If there are 9 total nights, this would be ~73,800 files. Yet the Response goes on to say that "last year a total of 8,240 files were labeled by BCID and 580 bat calls were analyzed visually." Assuming the study design was similar between years, this sounds like ~8,200 files were everything that was collected over the entire study, not ~8,200 files on a nightly basis.
Follow-Up Answer: When this was answered, some bat detectors were still in the field collecting data. Answer was provided for what data had been collected so far to provide an idea of what to expect/anticipate. The reason for the large difference of calls collected verses analyzed last year is likely due to the many calls that were collected were not bat calls at all, but other noises picked up by the detectors (i.e., cicadas, other insects, etc.)
thus requiring no manual vetting.
3. Question: Was the data collected in full spectrum or zero crossing?
Response: The Anabat Swift records files in full spectrum format
4. Question: Will all log files be included with the WAV file?
Response: Yes, the park will send all raw data (SD cards) to the contractor after award.
5. Question: Can the detector settings be provided so we can determine the percentage of non-bat/noise files we can expect?
Response:
6. Question: The scope of work mentions using the NABat "renamer" program and a "renamer" checker, is it expected that we utilize SonoBat DataWizard for this process?
Response: The NABat site (Prep + Process Data | NABat (nabatmonitoring.org) offers guidance on the use of multiple approved software suites to process and rename acoustic recordings to include Kaleidoscope Pro, Sonobat, BCID, Echoclass, and Analookw. Contractor can utilize any one of these approved software.
