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.
