I have published a new review about of a field research birdsong listening device named OwlSense. The device will run for up to 700 hours in the field without the requirement to swap out its battery. OwlSense was developed by an Owl Research Institute technician through his work for the Owl Research Institute. My unit is running deep in the Superior National Forest and is well off the grid. I like the fact that I may run the device all night long but then also for the first hour after sunrise and capture the dawn song.
As always, I purchased OwlSense with my own funds, and received zero financial support for my review. My blog is 100% non commercial. Here is my evaluation: https://www.365daysofbirds.com/2025/11/28/bird-song-listening-field-research-device-owlsense-chirpity/ ---- General information and guidelines for posting: https://moumn.org/listservice.html Archives: http://lists.umn.edu/archives/mou-net.html
