Amphibians raising young
One of the biggest bonuses when we installed our pond was that we were able to watch both green frogs and American toads mate and lay eggs. Watching the eggs develop into tadpoles and then adults has been fascinating.
Toads need a water source like our ponds only in the spring breeding season since their tadpoles develop and leave the pond in just a few weeks. Green frog tadpoles develop more slowly, so temporary spring ponds (vernal ponds) aren't enough.
Green frogs have a mating call, but it's not nearly as melodious as the toad's. It's more like a banjo twanging (though equally persistent!).
There are more than two frogs in this photo, and evidently, there's often a pile-up. In fact, we've read that sometimes the whole "frog ball" will actually sink. When they all sort it out, there will be just one male and one female.
The green frog tadpoles are much larger than the toad tadpoles. It was very interesting seeing both the toads and green frogs develop.
Unlike toads, the green frogs will overwinter as a tadpole. They develop much more slowly, which is why they don't reproduce in vernal ponds as toads do.
(Vernal ponds are those very important, temporary ponds found in woods and in other places.)
