Tis the season of love all around us. Birds, insects, mammals and especially amphibians are all trying to pass on their genes to the next generation. Male frogs call in the hopes of attracting a female to mate with, being selected based on the volume a frequency of his call. Males will call almost continuously through the peak of the mating season, day and night. I have seen dead frogs in ponds that, I can only assume, have literally called themselves to death.
The Northern Leopard Frog is amongst the first frogs to begin calling in the spring. They will call at he surface or just below making a call that is very difficult to describe in words.
The green frog is a large frog, second only to the bull frog in Minnesota. The green frog is a late season caller and wraps up the mating season for amphibians around my house. Their call sounds like plucking an out of tune banjo. Their tadpoles will spend the entire next year underwater before emerging as young adults the following summer.
Frogs, and other amphibians, are an important of the environment, serving as predator and prey for many other species. Unfortunately their global populations are falling as human influences to environment continue to marginalized their habitats and other needs for life. Amphibians are an indicator species of overall health of an ecosystem. If global populations are decreasing what does that mean for the overall health of the planet??
