Toad in my Abode

On Friday we had a toad visitor, found in the garage. I held it, and it was real nice. We released it near the pond, and it ate a bug and then crawled off into the vegetation. I had been wishing for toads because unlike frogs, you can easily hold them. I hope we see him again. As for the tadpoles, I found a couple more dead ones, which had legs! Fully formed thighs and calves, but still very puny. They were still attached to the tail, but I saw some live ones with the legs already free from the tail. So that was neat. I wonder what will happen when they all are ready to fledge? If they will stay in the pond or disperse? And I wonder how long it will be until that happens.
