frog calls

Larry reminds us that April 9 of last year broke an overnight low temperature record, silver maples have gone bloomin' crazy, the lake effect is slowing the progress of spring the closer you get to it, and he's celebrating over twenty years of tracking frog and toad populations in northeastern Minnesota.

You can find out more about the Minnesota DNR's Frog and Toad Calling survey, plus find a number of helpful links right here.

Even if you don't understand a word your friend Jeremiah the bullfrog says, the DNR still wants you to listen to him.  

Actually, they're looking for volunteers all across the state to spend  a little time this weekend being "citizen scientists" and, just as with various bird counts through the year, listening for frog and toad calls and jotting down data. (And there are still some routes open up here in our neck of the woods)

This is the 21st year of the survey - and the statewide volunteers who make it possible.  And this year, there's even an app.

On Wednesday, we told you a story about a frog survey being done of the vernal ponds at Hartley Park.  Ryan Hueffmeier of the NRRI says its a listening survey, conducted by himself and citizen-scientists just after dark or before dawn.

Just this last week, naturalist Larry Weber took part in a similar survey: driving a 20 mile route and making stops at 12 dedicated wetlands to listen for frog calls.
