Sunning snappers, cavorting cooters and spirited sliders – unexpected behavioral encounters

All wildlife fascinates me. It’s always a delight when some animal exhibits behavior in my presence that I haven’t seen before. Turtles have not been the most likely candidates in this regard for me, however. That changed this year in two cases (see further below). Mostly I see them basking on logs in bogs, ponds and lakes, like these yellow-bellied sliders (Trachemys scripta), either alone or in the company of other creatures.

Painted turtles (Chrysemys picta) also like to sun and can be seen in the same environments.

Seeing turtles cross a walking path as they search for a place to dig a nest for their eggs is not unusual.

I’ve come across a red-eared slider (Trachemys scripta elegans) also on the march, apparently having just completed a nesting site.

There are seven species of cooters (Pseudemys) in the southeastern USA and it can be difficult even for experienced naturalists to distinguish them. They are all large turtles at full growth, with a carapace measuring some 13 inches or more.

 

The turtle that many more people see, including in their yards, is the lovely Eastern box turtle (Terrapene carolina). During nesting season they are often on the move and several people I know will stop and “rescue” them as they cross busy roads.

The other day, I stopped traffic on a busy neighborhood road when I spotted a box turtle crossing. Drivers of cars going both ways kindly came to a halt as I carried the turtle to the side of the road where it was headed. It was about the 5th time this summer and fall that I had stopped for a box turtle and I always hope that the reptile will go on to have a long and healthy life.

This summer I also rescued a box turtle that I found resting on water weeds in my pond. I had always thought that these terrestrial turtles would drown, so I got the reptile out. There is a small log sticking up out of the pond, which is how I think the turtle got in, but I wasn’t sure it could climb up again.

I did find out later from my friend Lucretia that box turtles are able to swim, despite not having webbed toes like aquatic species.

The box turtles vary a lot in coloring, but the turtle below has to be the most strikingly colorful one I have come across so far. It made me think of a young person who went a bit wild with the make-up.

The slider turtles can also have some beautiful coloring.

One bit of behavior that I don’t expect from snapping turtles (Chelydra serpentina) is the basking behavior exhibited by many other species. Nevertheless, in June I found one apparently enjoying a sojourn in the sun in a pond kept filled by the local beavers.

Usually, I see snappers with their heads tucked in, but they certainly do earn their scientific name of serpentina (snake-like) as their necks are very long!

And that brings me to the really unexpected behavior that I recently saw while watching turtles. One day, about 20 turtles were swimming and gliding around a pond, close to the surface. Two in particular were not only swimming, however, but also seemed to be playing. After asking for help in identifying them in a reptile-oriented Facebook group, it was suggested they were either sliders or cooters. Both were very large.

They were not near one another but in their own space, showing similar behavior. They would surface, swim along with their bodies stretched out to the limit and then bring up their hind or front legs and slap the surface of the water repeatedly. Then after doing this several times, they would suddenly rise up a bit and splash their whole bodies down into the water, making an even larger spray of water.

A fellow photographer suggested they might be mating or defending territory, but I think they were actually playing.

Some readers might think that makes me very anthropomorphic, but scientists are studying the concept of play in reptiles and one researcher, Gordon Burkhardt, has said that rejection of the idea of reptiles playing has to do with how play is defined.

He has proposed a definition that would make it entirely possible to think of reptiles playing:

“play is repeated, seemingly nonfunctional behavior differing from more adaptive versions structurally, contextually, or developmentally, and initiated when the animal is in a relaxed, unstimulating, or low stress setting.”

It should be noted, too, that websites dedicated to people who own reptiles as pets include articles on how they can stimulate play – and thereby well-being and health – among their animal companions.

I’ll be keeping a more watchful eye on turtles from now on; who knows what other interesting behaviors might be observed? And it would be just nice to think that a turtle whose remains we find in the woods could have had an enjoyable and not just “mechanical” (pre-programmed) life.

As Brian Doyle wrote in Martin Marten:

“The fact is that the more stories we share about living beings, the more attentive we are to living beings, and perhaps the less willing we are to slaughter them and allow them to be slaughtered. That could be.”

 

 

 

See anything good?

Sandy Creek path IMG_4981© Maria de Bruyn resThat’s a common question I get when I am out on one of my nature walks. Since I carry a camera with a large zoom lens and often a smaller camera, too, it’s obvious to passersby that I’m out observing nature. And I realize that when they ask the question, what they really want to know is whether I saw anything unusual or spectacular.

A recent walk at Sandy Creek Park in Durham, NC, was a case in point. I told one couple who posed the question that my most memorable sighting so far had been a male ebony jewelwing damselfly (Calopteryx maculata) – the iridescence of its body and wings in the sunlight was wonderful. They smiled a bit uncertainly and the lady of the pair admitted that she didn’t know anything about damselflies as they walked on.

Fragile Forktail damselfly I77A0648© Maria de Bruyn resAn hour or so later, another couple asked if I had “seen any good ones?” I repeated my delight in seeing the male damselfly, adding that the female is not as striking with her brown color and white spots. “Yes,” said the man, “that is often the case with other species. In our species, though, it’s the females who shine.” That may be the case some of the time, but my day was made by seeing a female damselfly that was a member of a new species for me – the fragile forktail (Ischnura posita).

 

My experience is that I find some beauty in almost all the wildlife I see (ticks and chiggers are an exception). So I want to share a few of those “good things” I saw at Sandy Creek Park last month in a two-part blog “tour”. In this first part, I’ll continue on with the insects.

Identifying dragonflies is not easy since the females and males can look quite different. The great blue skimmer (Libellula vibrans) provides an example – the male lives up to his name with a blue hue and large size, but the female shows off her beauty with a brown and yellow abdomen.

The Eastern pondhawk (Erythemis simplicicollis) has distinctively different appearances as a male and female. The adult male is a blue individual, sometimes with a bit of greenish tint; the female – and the immature males! – is brilliant with different shades of green. I remember being excited when I first spotted a female as their green color is so striking.

blue dasher I77A0172©Maria de Bruyn resThe blue dasher dragonfly (Pachydiplax longipennis) has some stripes, as do some of the bumble bees. The brown-belted bumble bee (Bombus griseocollis) lives up to its name with a brown stripe, while this American bumble bee (Bombus pensylvanicus) feeding on a trumpet vine (Campsis radicans) has white bands. Like honey bees, the latter bee has pollen baskets (corbicula) on its hind legs in which it stores pollen. I enjoyed watching this individual – s/he would dip down into the flower, back up a bit, and then plunge forward again, almost always keeping the pollen basket above the tip of the flower.

The pollen gatherers were numerous during both visits and willing to share the sources of their bounty – here you see a bumble bee (Bombus), syrphid fly (Toxomerus marginatus) and sweat bee (Halictus) feeding peacefully together on a coneflower (Echinacea).

The milkweed plants were attracting many species of pollinators; here an Eastern carpenter bee (Xylocopa virginica) was enjoying a meal.

While there were many, many bees the days of my visits, there were fewer butterflies but the common buckeye (Junonia coenia) was stunning!

 

 

The little wood satyr (Megisto cymela) and dun skipper (Euphyes vestris, to the lower right on the milkweed) were not as colorful, and some people might even call them dull, but they are still nice to see and the Eusarca moth (Eusarca confusaria) was also an evenly colored beauty. I had grown up thinking moths usually fly at night, attracted by lights so it still draws my attention when I see them in the daytime.

Even a somewhat tattered American lady (Vanessa virginiensis) offered a pretty view.

The broad-headed sharpshooter (Oncometopia orbona), a leaf hopper, and the spotted pink lady beetle (Coleomegilla maculata) are tiny but such colorful insects that close perusal of the vegetation helps you spot them (and presumably makes it easier for birds to see them, too?).

One beetle that we don’t really want to see is the emerald ash borer (Agrilus planipennis), an invasive species that came to the USA from Asia. The larvae of these beetles kill ash trees and the park administrators have hung a trap box for them to determine whether this species has reached the park.

 

 

Spotting mammals is not always easy at the park but one day fellow birder Jim was kind enough to alert me to an opossum (Didelphis virginiana) in a tree when we met on a walking path. He told me approximately where it was and I spotted that one and another in a nearby tree; I thought it might be a mother and grown offspring but that was a guess and I certainly couldn’t confirm it. As these are nocturnal animals, it was pretty cool for me to see two in broad daylight. The only marsupial found in the United States and Canada is a beneficial animal for us humans (and other wildlife) as they could eat up to 4000 ticks in a week!

One of the pair demonstrated that they can open their jaws widely – watching him/her slowly stretch that mouth offered me a surprise; I would think it couldn’t go any further and the animal continued to show that s/he could really please a dentist who would like lots of space to investigate those teeth.

The Eastern cottontail rabbit (Sylvilagus floridanus) was not so lucky, carrying a fat tick in its ear. Too bad the opossums couldn’t come by and groom him/her and remove that pesky arachnid!

 

The park is not only attractive for the entomologists. Reptile enthusiasts can spot turtles fairly easily, especially in the spring when they are looking for places to lay their eggs. A large painted turtle was crossing a field looking for a spot, while an Eastern mud turtle (Kinosternon subrubrum) was trundling down a paved path one morning, not far from a pond which often has many painted turtles and red-eared sliders (Trachemys scripta elegans), like this one – who must have been a bit bothered by a bird feather caught in its shell.

Which bird could it have been? I’m thinking a swallow – see part 2 of the tour for a view of the species and more of the wonderful biodiversity that can be seen in the park.
