Field Survey

Our Field Survey training workshops integrate both contact and non-contact survey techniques for studying bats during an intensive 8-day / 7-night schedule.  Students learn capture methods using harp traps and single-, double-, and triple-high mist nets. Bat removal and handling skills are featured, as are in-field morphological species identification metrics. Non-contact survey methods using photo, video, and audio recordings are combined with physical captures to demonstrate species-specific survey protocols. Full-spectrum bat detectors are featured for collecting active, passive, and mobile transect acoustic data. Students receive guided, hands-on experience with the deployment of all survey methods, data-collection, analysis and reporting. Workshops are conducted at prime field locations across the country where all activities are a part of on-going long-term, bat surveys at each venue.   

 

Program Details

The Field Survey training workshop combines classroom learning with in-field demonstrations and real-time data collection during daily, hands-on guided analysis and recording. This provides students with the full range of methods, techniques, and technologies available for surveying bats in any North American habitat. Multiple inventory and monitoring methods will be used each day, alone or in combination to illustrate how each have different capture biases. By the end of the week, participants will learn how to adequately sample a diverse habitat to document species occurrence, diversity, and relative abundance.

Instructors will illustrate important site-selection criteria for both capture and acoustic deployments and students will have opportunities to perfect micro-siting skills for harp traps, mist nets, and bat detectors. Other audio and video recorders will be demonstrated for recording bats at roosts, during evening out-flights, and near foraging areas. These efforts will be combined to provide a “big picture” of bat occupancy and allow students to apply various techniques to their home survey efforts.

Note: Proof of current rabies vaccination or acceptable titre level is required for any students wishing to handle bats. Documentation must be dated within 1-year of the start of this training. (Students do not have to handle bats if they prefer to concentrate on other survey methods during the training.) A laptop with the Microsoft Office suite is strongly suggested for all students. All capture and recording equipment is provided. Bat detectors are available to borrow, but students are also encouraged to bring their own to use or compare with other models. Students will receive download instructions for trial versions of all acoustic analysis software. Our complete agenda is available on-line for review. Students are encouraged to bring previous acoustic data and/or any questions about hardware, firmware, software or survey protocols for 1-on-1 “geek sessions” with the instructors.

Consider Adding the Optional Zero-cross Module to this Training
All our trainings emphasize regional bat classifications of "full-spectrum" acoustic data using KaPRO and SonoBat software, but when the last day of the training concludes at noon, we will offer an optional extended mini-course to demonstrate workflows for processing zero-cross files in KaleidoscopePro for analysis in BCID and EchoClass. Instructors will guide participants on how to interpret the BCID and EchoClass automated outputs and use AnaLook and KaleidoscopePro to manually vet file-level classifications to confirm or reject MLE’s for species presence. Lunch on this day and an additional evening data management geek session is included. Participants must register separately for the optional Zero-cross Module.
