First, I posted a picture of this small, inexpensive box on December 28, 2019. Briefly, they cost about US$2-5.00. Made in China and available on eBay. Convoluted foam inside top and bottom. I drilled out a hole in the top 7/16 inches and installed a 1/2 inch rubber grommet. Inside the lid I taped part of the original plastic bag all the way around. I placed the microphone directly under the hole in the case. The grommet does two things; secure the AudioMoth in place between the foam layers, and provide just enough of a raised 'bump' to ward off drips of rain that might otherwise ingress. They may help with deflecting wind. I did not have much rumble, but my attention was fixed on owl vocalizations, not wind. I deployed 4 AudioMoths in these boxes over 1138 hours of night recording. I used 14 inch cable ties to secure the unit to a small tree by the tabs, and wrapped the boxes in camouflage stretch tape, available on Amazon. Some deployments were in state parks filled with curious humans, others in remote areas filled with curious wildlife sniffing and poking. I never lost a box or a unit, and none every failed, or came loose from a secured location. I brought the last unit in this morning; it was out for 5 nights, recording 10 hours a night, one of which featured a major storm which dumped 2.5 to 3.5 inches of rain. The unit was completely dry, all 200 fifteen minute recordings were clear, and I did not find the screech-owls I was searching for.
