A very busy Yellow-rumped Warbler was zipping back and forth over the edge of a small pond.
He found small twigs to perch on between forays.
And then totally surprised me by landing in the water, which is much deeper than just to his ankles.
The carpet of vegetation, or perhaps a stick under the surface, was enough to hold up his 0.4-0.5 ounce (12-13 g) body while he poked in the water.
He got his treasure and skedaddled showing off his name-sake rump.
