Snapping Turtle Seeking Sandy Soil In Which To Lay Eggs
Monday’s Mystery Photo leaves no doubt that Naturally Curious readers are among the most informed nature interpreters out there. There were many correct answers, but congratulations go to Susan Cloutier, who was the first to identify the tracks and diagnostic wavy line left by the tail of a female Snapping Turtle as she traveled overland seeking sandy soil in which to lay her eggs. The turtle eventually found a suitable spot, dug several holes and chose one in which to deposit her roughly 30 eggs, covered them with soil and immediately headed back to her pond, leaving her young to fend for themselves if and when they survive to hatch in the fall.
Unfortunately, there is little guarantee that the eggs will survive. Skunks (the main predators), raccoons, foxes and mink have all been known to dig turtle eggs up within the first 24 hours of their being laid and eat them, leaving tell-tale scattered shells exposed on the ground. Fortunately, Snapping Turtles live at least 47 years, giving them multiple chances to have at least one successful nesting season. (Thanks to Chiho Kaneko and Jeffrey Hamelman for photo op.)

Tadpoles Vulnerable To Drought
Congratulations (again!) to Kathie Fiveash, the first Naturally Curious reader to correctly identify the rough patch in Monday’s Mystery Photo as tadpoles that were stranded in a puddle that was drying up.
Most tadpoles acquire oxygen in a number of ways — through gills, through their skin, and by breathing air into their lungs. In this case, a lack of access to oxygen in the water has left them high and dry, as their lungs are not developed enough to provide them with the necessary amount of oxygen from the air. A sad ending for these young frogs, but a goldmine for scavenging raccoons, skunks, foxes and birds.

Meadow Vole Circles
Congratulations to “Maine Naturalist” and Stein for identifying not only that a Meadow Vole made the mystery tracks, but why they were circular! Thank you all for your comments, many of which were laughter-producing!
More NC readers have witnessed this phenomenon than I would have imagined – the tracks were made by a Meadow Vole that had neurological problems which could have been caused by a brain parasite, brain tumor, inner ear infection, or a stroke. While the exact nature of an affected vole’s neurological impairment cannot be confirmed without the vole in hand, it is highly likely that a common brain parasite, Toxoplasma gondii, is responsible for a vole running in circles.
The snow-covered corn field where these tracks were located was just down the road from a dairy farm, where it’s likely cats could be found. This is relevant because cats pass this particular parasite on to rodents (and birds) who eat the cats’ feces. The parasite goes to work on the brains of animals that have eaten cat feces, causing them to become disoriented (to the point where they lose their fear of cats). Cats then eat the fearless rodents and the cycle continues. When infected and disoriented, the rodents will often run in circles – hence, the unusual track pattern in the snow.
T. gondii can infect humans, too, through consumption of under-cooked foods, contaminated drinking water, and through contact with cat feces. This is why pregnant women are discouraged from tending kitty litter boxes, as the parasite can infect their unborn children.

Whirligig Beetles Active
Congratulations to Stein Feick, the first person to correctly identify the Mystery Photo as a Whirligig Beetle! You usually see this aquatic beetle swimming around and around in circles on the surface of a pond searching for prey. A unique feature of most beetles in this genus is their divided eyes. Each eye is completely separated into two portions (see photo). One portion (dorsal) is above the water line and the other (ventral) is beneath the water on each side of their head, allowing them to see both in the air/on the surface of the water as well as under the water. The dorsal eyes have a limited field of view, so these beetles rest one of their antennae on the surface of the water to help them detect any motion caused by prey.

Mystery Photo: A New Perspective
In my desire to show a close-up of the shredded nature of the bark-stripping in Friday’s Mystery Photo, I didn’t take into account that knowing the height of the stripping was as crucial to solving the mystery as the shredded bark! Today, instead of revealing the creature that is responsible for this activity, I am posting a photograph that gives the viewer the perspective necessary to correctly identify the sign-maker. Please feel free to resubmit a guess with the aid of this added information if you would like to. The photograph was taken within the last two weeks, and the sign was very fresh. The bark stripper’s identity will definitely be revealed on Wednesday, February 26th!

Red Squirrel Belly Flop
Congratulations to Mary Pratt, the first reader to correctly identify the impression a Red Squirrel left in the snow. Red Squirrels are fiercely territorial, and will chase each other furiously in order to defend their territory and their food caches. The photographer, Susan Bull Riley, witnessed this behavior as she watched two Red Squirrels racing after each other in the crown of a maple tree. Suddenly one of them fell to the ground, where sleet and wet snow cushioned its fall and recorded the belly flop landing. No time was lost in the resumption of the chase!
There were many “Flying Squirrel” responses, which makes great sense as they are approximately the same size as a Red Squirrel (just an inch or two shorter in length) and are gliding from tree to tree or from tree to the ground. My assumption is that a Flying Squirrel’s landing impression might show some of the patagium, or membrane, that stretches from a squirrel’s wrists to its ankles, due to the fact that it is extended as the squirrel glides. (Any firsthand Flying Squirrel landing-in-snow impression observations welcome.) Thanks to all who submitted an answer to this Mystery Photo. Many were very amusing!

Mystery Photo
I am often asked how I find the subjects that I photograph. Sometimes I am consciously looking for specific plants and animals, but more often I’m simply looking for something that is either out of place or out of character. In this particular instance, I noticed an American Beech sapling with leaves that were bunched up into an odd shape. If you think you know what caused this roughly 2-inch long x 1-inch wide, leaf-covered cylinder, go to the Naturally Curious blog (www.naturallycuriouswithmaryholland.wordpress.com), scroll down to “Comments” and enter your thoughts. The answer will be revealed Monday, Oct. 7.
