Keeping Water - Episode 71: Pond vs Predator, Part One: Herons

In this week’s episode, we’re going to begin my look at predators by starting with the most common and prolific - the heron. In part, which will come out at some point over the winter, we’ll take a look at at least 3 other predators, including, possibly, the most dangerous.
