The breeding season for Red Fox is January in Central Illinois. And that is when they are the most vocal.

The following sound clip is an amalgamation of  four clips recorded during January of 2012. It was recorded using a Sound Devices 722 Field Recorder and Telinga Parabolic Microphone. The recorder was left running continuously from the patio of our home here in Central Illinois. The foxes run up and down the little valley  that our house overlooks.

I never knew a fox could make such sounds. Thanks for sharing this, Stan.
Absolutely a great recording Stan, and really interesting vocalizations. The first part of the recorded vocals sound like a fox but the second part could almost be misinterpreted as a person screaming. Since you leave your recorders out for long periods, do extremes in temperature (winter cold or summer heat) ever cause problems with getting your recordings? Thank-you for making your recordings available.
These foxes were recorded from my patio. The microphone setup is covered by three sides of the house, out of the wind and weather. The microphone cable goes through the wall and up to my living room where the recorder is.
With other recorders I take special precautions to protect all the delicate gear and microphones from the extremes of weather.
