Ducks on the Pond

The ice cleared the pond yesterday and a mallard pair took full advantage at daybreak today, hopefully scouting for a nesting site. Looking closely as the pond turned, we also noticed a half dozen goldfish lazily shaking off their winter sleep, testing the waters.
It's March 12 in Minnesota. Let's get started.

For some reason, the drake was closely monitoring the hen today. When she departed, he was quick to follow,
chasing her tail. A universal behavior known to other species. Never ceasing.
