In the Mandan Park area, it isn't just birds we hear singing in the trees. At night, we also hear the frogs singing, and yes, they really are in the trees!
When I first heard the frogs at night, I actually thought they were birds, and couldn't figure out why they would be making so much noise in the dark. Several years later, my sister found a tiny frog on top of her door, hunting mosquitoes, and when she looked it up on the Internet, she found out it was a tree frog.
Cope's Gray Tree Frog is native to Nebraska, and is usually found near wooded areas where there is water. They lay their eggs in shallow ponds or pools. The frogs that sing at night are actually the males, who sing in a chorus.
When I first began listening to the frogs and figured out what they were, I really only noticed them in my ash and hackberry trees. This summer, however, I have heard them all through my yard, and we have even seen them in the front of the yard, on the lilac bushes. Needless to say, this makes mowing interesting. Sometimes when the bushes get shaken, it appears to be raining frogs...which makes the mowing a very delicate operation indeed.
Most of the best years for frogs have, perhaps not surprisingly, been some of the best years for mosquitoes, as well. I used to wonder what kind of benefit mosquitoes could possibly bring, especially when I was swatting and slapping at them, but the preponderance of frogs in a bumper mosquito year almost makes the mosquitoes more tolerable. These frogs also eat grasshoppers, crickets, moths and flies.
If you would like to have tree frogs in your yard, there are 2 things that should do the trick...trees and bugs! Leaving a little water out might not hurt, either!
