Peeper's Puddle

It was an annoyance at first -- a low spot in the barnyard where water collected after a rain. The horses would mix it up into a muddy mess. Our ducks -- Peeper and Bean -- were the initial pond engineers that got it to hold water. I think their constant churning of the mud as they filter for insects caused it to stratify, with the silt and clay settling in a sealing layer that held in the water. It gained a degree of permanence, but was still just a puddle.

It was about five years ago now that I decided to help them out, digging first with a three-point scoop on the tractor and then some more with the horses using a slip-scraper. It held water, but was still pretty small at first, and summertime turned it into a tub of red or green algae, as it captured much of the barnyard effluent.

Mosquitoes laid their eggs there, but mosquito eating insects arrived in short order and kept them in check. Frogs, and especially toads, started to congregate there, mostly during spring mating season.

The toads have become so numerous that I have to be careful not to step on them after it rains, when herds of them can be roaming the yard. The pond is now the site of their annual spring orgy, where they sing all day and become so focused on making tadpoles that they don't mind me standing right over them. Curious about a writhing mass of something I could see in the water a few weeks back, I investigated to find four males all clinging to a dead female that they had probably drowned in their amorous enthusiasm.

It didn't take too long for Henry to discover the pond and start seining it for signs of life with his butterfly net. He found all sorts of bugs and insects that I knew next to nothing about: giant venomous water-bugs (aka "the eastern toe-biter"), water-scorpions, giant diving beetles, backswimmers, boatmen, and a bunch of others too numerous to mention. Before long he had an aquarium of them in his room where we could watch them all eat each other.

Visiting geese
A few years ago, we were given two dozen Rouen ducks. Their constant nibbling really stirred up the mud and sealed the pond even more, to the point that the water is rarely more than a few inches below maximum height now.

It's big enough to skate on in the winter, and couldn't be a more convenient skating rink. Henry has
 made great use of it, playing hockey with a stick for a puck, and our border collie as the opposing team.

When the ice melted this spring, he made another interesting discovery. A bluegill we'd released into the pond last summer had apparently survived until the winter, despite the pond being perhaps 3' deep at the center. With a little more depth (and probably a bubbler) perhaps we could keep some there year round.

Birds are making great use of it now. We have a sandpiper or two who regularly visits to march endlessly around the shore while searching for bugs in the mud. Occasionally we get a few canada geese or mallards, and have even had herons and sandhill cranes visit a few times. Doves regularly come down for a drink, and starlings use it for their baths. Barn swallows use it to collect mud for their nests. They swoop through the air above it for hatching insects throughout the day, while bats take the night shift.

A number of painted turtles have taken up residence, and regularly sun themselves on the log we've placed in the water for them. There are snapping turtles as well, but they don't show themselves so often.

I have big plans for the pond. More digging to make it deeper, and perhaps introducing some cat-tails or other aquatic plants. I suspect that more places to hide or lay eggs would benefit many of the residents. Until I'm moved to do so, I'll just keep watching. It's some of the best entertainment around.
