Reply to comment by GreenStrong in How do fishes get into isolated inland lakes in the first place? and why don't we see more divergent evolution / speciation given the separation of each group of fishes from each other? by I-mean-Literally

Would this also explain how frogs/tadpoles randomly turn up in my garden water fountain????

I mean, frogs can move on land, so I would imagine they just walk (hop?) there and lay their eggs.

Like it makes sense but I've just never seen a migrating frog before :p

Oh, I've seen that. I've had both tree frogs and pond frogs find their way into buckets on my porch and lay eggs.

I bought a house in Simi Valley, up in the hills. It’s basically a desert. Somehow little brown frogs made it under my house. I went down there to get them out because they were constantly croaking, and I found a broken drain pipe that was their source of moisture. How they managed to get from wherever they were to my place is astounding to me.

Possibly, but frogs are pretty industrious about hopping around and finding breeding pools. Many species prefer these transient pools where there won't be aquatic predators. I would guess that they can smell water. If you don't see frogs hanging around and signing during the day, tree frogs are a strong possibility.

I'm in North Carolina, and I get both green frogs and grey tree frogs in my pond if I don't have goldfish. The green frogs definitely hang out and sing for mates when there are no goldfish or only young ones, but they go elsewhere when the goldfish are bigger than an inch or two.
