Leopard Frogs Calling At Home

Tonight I am sitting on my deck listening to leopard frogs do their long slow snore.  I hear at least four individuals calling. How have I never heard this before? I mean, I have heard leopard frogs calling but never at home. I also hear a robin, many chickadees, some cardinals, a pileated woodpecker, and goldfinches. Today is a warm day. The inside of my house is still cold but it is warm outside. It was even warm this morning when I got up.  I tried to put the rain barrel in place for the season. I could not do it this morning because there was a tear drop chunk of ice right where I wanted to put the barrel. I tried to kick the ice out but I could not do it. This was a 5 inch tear drop of frozen run off. I decided to let nature take its course.  When I got home the ice had melted. Now the rain barrel is in place.  Now the leopard frogs are singing. If I was to guess what they were saying I would guess most of it has to do with mating but some of the snores must be gratitude that it is finally warm enough outside for frogs to sing.
