A local electronics shop is advertising night vision scopes x 3 magnification infra red monocular. Has anyone ever tried one? For owls etc? David Robertson Adelaide

Red filtered light in my experience affects neither bird nor beast. I once tracked a nesting pair of Frogmouths in this way. I set up camera in daylight on a tripod focusing on the nest and reset to manual focus. Once it got dark and the birds started to move I’d fire off a flash shot when I detected movement against the stars or faint sky. I used red cellophane over the flash and the birds did not react. I followed them through hatching and fledging (both chicks fledged). I’ve spotted for Owls likewise. At the Barna Mia endangered marsupial breeding enclosure at Dryandra they use large torches similarly filtered with red cellophane when they take people round for the supplemental feeding sessions. Provided everyone remains quiet and still the little critters cheerfully frolic around your feet oblivious to the light. ________________________________________ Sent: Thursday, 10 December 2015 8:22 AM I’ve tried a low-end device and can offer a few comments: * It’s hard to see things because the depth of field is so limited. * You’re staring at a small, glowing light which messes up your night vision entirely. * It’s pretty hopeless to scan the environment looking for animals through a very narrow tube. * If you can find an animal, some are clearly less disturbed by the infrared than a torch. Yellow-bellied Gliders are very shy of visible light but don’t seem troubled by this part of the spectrum. Someone posted some brilliant Glider films here a few months back from down this way (NSW Far South Coast.) Perhaps whatever videocamera they were using is a better alternative? If you’re staking out an owl hole or the like, it can be worth setting up this sort of gear on a tripod and then using a torch to quickly detect if an owl is around. If so, you can turn on this gear to get a look. I’d love to try out some high-end gear and see what it’s like.

I’ve used one with mammals at night. Works well. Sent from my iPhone
