From last year's Bufo americanus breeding season. The call is from 2 nights before the picture, but both are from the same part of the pond. It's representative of how I photograph calling toads/frogs. Your presence in the pond tends to shut them up but if you stay still long enough a far away one will start to call. Then the dudes you're right next to realize they might be missing out on the ladies and respond.
In the 'old days' before I picked up a simple voice recorder with built in speaker, I would also stimulate the nearby guys into calling by doing my best toad trill. It worked quite well but now I can both record them and play them back at themselves for encouragement (I'm a toad voice coach in my spare time). It's much easier on the throat and a little less embarrassing.
