Conclusion
We believe that HSV is a valuable noninvasive, economic, and practical
tool in CMR. The advantages of using HSV include improving data quality,
minimizing the physical damage to the study species, reducing sampling
efforts, and saving money that would be allocated to hiring field
assistants. The integration of HSV in CMR is timely because there have
been remarkable technological advances in high-speed video capabilities
during the past decade where cameras can generate high-quality HSV,
capture longer videos, zoom to far distances, process the recording
rapidly, and store large files. Nowadays, DSLR cameras have high
frame-rate video modes at reasonably low costs
(Steen, 2014). HSV could also be used in
CMR of highly-mobile birds and mammals. Future methodological
integration of high-speed camera might be in camera-trapping-based
studies (Rico-Guevara & Mickley, 2017)
to investigate demographic parameters, dispersal, home range, and
behavior.
