CharlotteOver the last week it has been raining and I’m not sure that the temperature has been above 50 since April 9th. I have been using this time to try and review the calls I’ve had. I’m very much enjoying listening to my recordings and trying to compare them to what I can find online. I have found some wonderful websites to help with matching the sounds and frequencies. The few times I have headed out during the cold temperature at night there’s not much activity. A few of the Spring Peepers can handle the cold, but it’s drastically quieter with calls.
I’ll try to keep a list under Links but this is the most recent website discovery. It is very helpful to combine sounds and visualization for learning.
