This seemed weird to us because we don't have a nearby stream or pond.
However, because of the strange, cool spring weather we've had our cement pond (pool) has had standing water for a few weeks.
Seems some tree frogs (at least four of them) hopped to the pond and have been calling out for mates.
We moved the frogs back to the tree grove, pumped out the water, and will try to get it ready for the season (read heavy chlorination, no chance for frogs or other creatures to survive) as soon as possible.
We also snapped a photo of one of these cute little frogs.
