Since it’s now summer here at Wildlife Acoustics HQ, we’d like to take this time to briefly talk about recording in hot weather.
(If it’s cold where you are right now, you can see our cold weather post here.)
The two most basic considerations in hot weather are batteries and mic windscreens.
Heat & Microphone Windscreens
The foam which is used in the microphone windscreens will break down over time with exposure to UV rays from direct sunlight. Even if they turn brown, which is normal, they are still useful until they begin to flake away. It is at this point that you may need to replace them. In fact, we recommend that users always order extra microphone windscreens when they are purchasing their equipment in case they degrade or they’re eaten by wildlife. That way you save on shipping costs and have back ups in the field.
Batteries & High Temperatures
As for batteries, the chemicals in batteries generally speed up their rate of reaction the warmer it gets. This means that the higher the temperature, the shorter their lifespan will be. We won't go into detail about battery chemistry, but keep in mind that you may need to replace your batteries more often if you are recording in warmer weather.
Lastly, always be aware that extreme temperatures and/or direct sunlight can cause damage to any electronics, including your Song Meter recorders, if they are placed in temperatures higher than for which they are rated. You can find those exact specifications here.
Happy recording, and don’t forget to wear sunscreen!
