I have Eastern Gray Treefrogs (Hyla versicolor) that visit my ponds to breed. I live on the edge of a 15-20 acre mini-forest, very mature trees I guess 80+years for the biggest.
I can't find any info on this, just observation from myself and my wife. We've noticed that these frogs only seem to come around to breed every two years? Is this true?
I swear, they are only out calling every other year, and that's the only time I find eggs/tadpoles. They are impossible to miss, they are loud as... motorcycles or so.
You know anything about this?
