Flipped a Rock

Published by at 7:00 am under Books & Events

Unnoticed among the 10th Anniversary commemorations of 9/11 is this:  Today is also International Rock Flipping Day (IRFD). 

Back in 2007  Dave Bonta and Bev Wigney started “Rock Flipping Day” as a blog carnival — a day in which to look for and blog about Nature in an unlikely place.  It immediately became an international event when bloggers from four continents posted their findings under rocks around the world.  Susannah Anderson (Wanderin’ Weeta) now organizes the event on the second Sunday of September.  In 2011 it happens to coincide with an important day in U.S. history.

I’ve participated in IRFD since 2009 so I decided to flip a rock despite today’s somber tone. 

My chosen rock is in our city backyard in Pittsburgh, Pennsylvania.  It’s not actually a rock but a large concrete paving tile in the alley behind our back fence.  My husband helped by lifting one end while I snapped away with the camera.  You can see his feet as he holds up the slab.

 

What have we here? 

Tunnels and trash. 

The tunnels are easy to see.  Inside the tunnels are two bits of trash, positioned as if dragged there by the tunnel-maker. Only one is visible in the picture.  The square in the center of the photo that’s faintly yellow with a turquoise stripe is a piece of cellophane wrapper.

What lives in the city, makes tunnels, and pulls trash into them? 

A gray-colored rodent with a naked tail.  :(

I didn’t expect to find this.  It’s creepy to think the tunnels were made by a rat right there behind my back fence, but what else could it be?  The slab is in the alley where everyone keeps their garbage cans.  

I have seen lots of wildlife in the City of Pittsburgh: hawks, owls, a bald eagle, groundhogs, raccoons, white-footed mice, deer, a red fox, even a toad. Just because I rarely see rats doesn’t mean they aren’t here.

Fortunately nothing moved under our rock and the tunnels don’t look recently used.  Perhaps our “visitor” moved on when I stopped feeding the birds in the spring to keep away rodents this summer. Or maybe an owl or a red-tailed hawk ate him.

I can only hope! 

Update: I did some research and I am very relieved! The tunnels are nowhere near large enough nor long enough to be rat tunnels. The tunnels under my rock are about 1″ in diameter and have straight-ways less than 6″ long. Rat tunnels are 3″ in diameter and 2 to 6 feet long. So the rock had a small rodent under it. Perhaps a mouse. I can cope with that!

    This past Thursday morning while rowing just south of Washington’s Landing a peregrin flew in and landed in a tree just next to the river. Beautifuly spotted and white on bellie and wings as she/he landed. It made my day!

    Well, it was two days early, but I found a baby garder snake while mowing my grandparents’ lawn. It was the first snake I’d seen in their yard, so it was kind of exciting. I also saw a small raptor fly over, probably an American Kestrel. After your experience, Kate, I don’t think I’ll go flip any rocks over in the dark tonight! (Although you’ll be glad to know that I drove off all the local wildlife in my yard by over flipping rocks when I was younger.)

    Dear Mrs. Red-Tailed Hawk, please visit the alley behind my house and capture another meal just like the one you’re eating in this picture: http://www.wqed.org/birdblog/2011/06/24/performing-a-public-service/
    If you can’t come right now, please send a great-horned owl.
    Sincerely, KStJ

    Are you sure those are rat tunnels? They kind of look like just drainage tunnels, from downpours. I’ve got a few of those in my backyard at the bottom of my hill, not under anything, where the water runs in rivers when it rains hard. Just a thought.

    I am so relieved for you that it isn’t a rat! We actually had one in our house some years back; it came and went through crawl-space access. We had it, er, taken care of, but I was freaked out for some time. We’re in suburbia, and have mice, voles, ground hogs, fox, hawks, coyote, snakes, deer, turkeys (my favorite), raccoons, and possums that traipse through/over the yard at times. Once summer some monk parakeets, which live a mile or so away near the Long Island Sound, flew up to our backyard and spent the season. Very noisy but such fun to see.
