Muddy Sneakers Wild Encounters
Thursday, May 5th, 2011
It’s always such a pleasure to spend time in the woods at this time of the year. The weather is warming, the flowers are blooming, everything is turning green and growing, and the animal encounters are frequent and exciting!
On a recent expedition with Pleasant Gardens Elementary School in Marion, NC, we were able to explore a new greenway that has just been opened up to the public along the banks of the Catawba River in McDowell County. One of the first wild creatures we encountered were numerous Eastern Painted Turtles sunning themselves on floating logs in a temporary wetland pool adjacent to the river which was recently inundated by rising floodwaters caused by spring rains. Painted turtles easily live up to their name due to the many delicate stripes and other colorful markings on their heads, necks, and lower shell margins. Turtles, being cold-blooded reptiles, love to bask in the sun to warm their bodies but also need the beneficial rays of the sun for other reasons. A turtle’s shell is a bony expansion of their backbone and therefore is part of their skeletal structure. In order for a turtle’s shell to grow properly, they must manufacture vitamin D in their bodies which they get from the UVB rays of natural sunlight. Without the sun, a turtle’s shell can soften and cause a turtle, especially young turtles which are still growing, to sicken and die.
A little farther down the trail, we began to run into numbers of Fowler’s Toads moving about in the thick vegetation alongside the paved greenway path. The students were captivated by these interesting amphibians and we captured, observed, and then released several of them. Toads differ from many of their frog cousins by being much more terrestrial in their habitats but always returning to pools of water to lay their eggs. Their skin is also rougher and drier, with many small bumps or what many people refer to as warts. In fact, many people believe that if you pick up and handle a toad you will get warts! Of course this isn’t true. What looks like warts on a toad’s skin are actually tiny little glands which secrete a sticky, white fluid to deter animals that otherwise might try to make a meal of them. These secretions are actually a type of poison which is only released if a toad is attacked or handled extremely roughly. When a human picks up a toad, the worst thing that would normally happen is that a toad may suddenly expel a large amount of water from its body to help to frighten away an attacker. This is entirely harmless, but can easily take someone by surprise!

Many of the toads we met were males. How can you tell the boys from the girls? If you pick up a toad and it makes any kind of sound – it’s a boy! Male toads often make bird-like squeaks and trills when handled. The females are voiceless. Also male toads call to attract mates in woodland pools where they arrive on rainy spring nights from the surrounding forest where they live most of the year. A male fowler’s toad has an unusual call that sounds a bit like the bleating of a goat or sheep. Waaaaaaaaah! Waaaaaaaaah! Waaaaaah! is a common sound during warm spring nights in toad country. Toads and frogs, just like birds, can be identified by their different mating calls.
A warm spring day is also a great time to explore around the water for aquatic creatures as well. We spotted a couple of Northern Water Snakes and some toad tadpoles in a small pool beneath a bridge on the trail. We also spent some time wading into the shallow water along the banks of the Catawba River to look for macroinvertebrates, small species of animals, particularly insects, which make their home among the rocks in the water during the first part of their lives, but later emerge as adults which live in the nearby woodlands, usually as flying insects. One macroinvertebrate we encountered in unbelievable numbers were tiny black aquatic freshwater snails which seemed to be scattered as a coating over almost every rock in the shallow water. We also encountered one of the largest dragonfly nymphs I had ever seen in the water there. Adult dragonflies are large flying insects known to just about everyone but many people are totally unaware that they begin their life underwater. The immature dragonfly is a mighty predator with an unusual and enormous folding mouthpart which it extends to grab various insects and other aquatic creatures as food. Watch a flying dragonfly closely sometime and if it is a female near the water, chances are that you will see it dip down to the water’s surface for just a brief second – as it lays its eggs which then sink below the surface to begin the first stage of the dragonfly cycle of life.
Another interesting aquatic macroinvertebrate we captured was a helgrammite. These long, flattened, soft-bodied creatures have sharp pincers to use as a weapon or to procure food so they need to be handled with care. Fishermen love to catch them and use them as bait for trout, bass, and other gamefish. The adult stage of the helgrammite is known as a dobsonfly, a large flying insect with long, clear, membranous wings. The male dobsonfly has long, pincer-like mouthparts that overlap and resemble tusks but they are totally harmless and useless as a weapon. Dobsonflies sometimes turn up at porch lights at night during the late spring or summer months.
As you can see, there are lots of wild encounters to be had in the spring woods. So why not get out and take a walk in the woods this May and be sure to stop and take a close look at the natural world around you. You never know what you might discover.

Butterflies are masters of camouflage and mimicry. Often, the larvae or caterpillars are camouflaged to look like leaves, sticks, or even dung! As adults, some species look almost identical such as the Red-spotted Purple and the Pipevine Swallowtail. The Pipevine Swallowtail is toxic to birds whereas the Red-spotted Purple is perfectly tasty, but they look so similar that birds are likely to avoid them both so this copy-cat strategy of mimicking a toxic species provides protection for the Red-spotted purple!
