New Life in the Pond: Tiny Tadpoles

From Theresa:
This is the fourth Summer after we constructed our wildlife pond... 
and we're thrilled to see tiny tadpoles swimming around in it for the first time
(see the black spots hugging the rock).
At least we assume they're tadpoles, either that or Bear says they're "sperm dark."

Here's a close up:

This is also the first Summer that we've been serenaded by multiple frog songs as we fall asleep.
Maybe this is one of the parents... Bear met him by our wood pile:

This is also the first year that any plants overwintered in the pond- 
we're seeing a lot of native arrowheads popping up (Sagitarria latfolia, which have edible tubers).

This is what the pond looked like this morning.
