HOME RUN DAY: Four Turtle Species

Monday, May 5th, 2014

Tiny One Inch Painted Turtle (Chrysemys picta) Hatchling

Saturday proved perfect for turtles and turtlologists.  With luck and pluck, the Turtle Journal team encountered four species of local turtles.  Sue Wieber Nourse started the streak by finding this perfect little painted turtle (Chrysemys picta) hatchling basking in a SouthCoast bog.

Tiny Over-Wintered Painted Turtle Hatchling

The tiny critter’s shell measured 2.46 centimeters long, less than an inch, and the hatchling weighed a mere 5 grams (less than 0.2 ounces).

Tiny Painted Turtle Hatchling with Absorbed and Healed Yolk Sac

Examining the center of this hatchling’s abdominal scutes, we observed the healed remnant of the absorbed yolk sac, clearly indicating that this baby had been born in the fall and recently emerged from its first winter’s slumber.

Large Male Snapping Turtle (Chelydra serpentina)

At the opposite end of the spectrum from the tiny painted hatchling stands this large male snapping turtle.  We snagged this 35-pound specimen at a local SouthCoast bog.  The adventure of that capture is documented in Snapper Hunt, a Turtle Journal posting from May 4th.

Male Eastern Box Turtle (Terrapene carolina carolina)

In between the extremes of tiny hatchling and large snapper, we observed a bright yellow, almost glow-in-the-dark male box turtle.

Measuring around 6 inches in shell length and 1 1/4 pounds, this fellow sported the most riveting crimson eyes, complementing a color scheme that screamed “gaudy.”

Adult Painted Turtle and Spotted Turtle Pair

We also found an adult painted turtle and several pairs of spotted turtles (Clemmys guttata) in a local SouthCoast bog.

Release of Spotted Turtle (Clemmys guttata)

Spring in the Great White North has been cold, late and lacking any heat spikes.  By this date, we should have been able to add a fifth local species, the Northern diamondback terrapin (Malaclemys terrapin terrapin), to the list for May 3rd.  As reported in Amazing First Terrapin Capture in Windy Sippican Harbor, we captured our first and only terrapin of the 2014 season on April 14th.  Since then, the weather has turned cold, windy and punctuated by storms.  Terrapins have plunged back to the bottom, turned off the lights, covered themselves with another layer of ooze, and are waiting for a saner weather pattern to set in.  Fortunately, the Turtle Journal team has kept busy with spotted turtles who are considerably more cold tolerant and less fussy than diamondback terrapins.  Give spotteds a bit of sunshine and a taste of 50 degrees, and they’re ready for action in secluded mating aggregations across the SouthCoast.

What Lies Beneath Every Pond and Lake?

Count your fingers, count your toes; if you’re diving, check your nose!  Peer deeply through the murky darkness into the mucky bottom of every pond, lake and favorite watering hole, and you’ll find a large, humorless, 35-to-60 pound snapping turtle … waiting.

Aggressive Male 35-Pound Snapping Turtle (Chelydra serpentina)

Every encounter with a snapping turtle is memorable; the bigger the turtle, the more memorable the event.  We were fortunate to find this pleasant critter cruising the bottom of a flooded SouthCoast bog on Saturday morning.  Water magnifies objects and creatures.  So, Don Lewis discounted the enormity of the image Sue Wieber Nourse spotted as he readied the net to bring the creature ashore for closer examination.

Snapper!

The video speaks eloquently for itself.  And it poignantly reminds us to be careful for what we wish; after all, we may get it.

Rufus the Turtle Dog Exclaims:  “That’s no turtle.”

When Don lugged this large snapper on shore, Rufus the Turtle Dog examined it closely with furrowed brows.  She looked up at Don with thought bubbles projecting, “That’s no turtle.”

Rufus the Turtle Dog:  “That’s a dinosaur … and it’s all yours!”

She stood up, walked away from the creature and formed more thought bubbles that said, “That’s a dinosaur, and it’s all yours!”

Sizing and Perspective for Male Snapping Turtle

The Turtle Journal team has a full complement of scientific devices for documenting field discoveries.  In the case of a very large, angry, and aggressive snapping turtle, we eschew those delicate instruments in favor of more durable, if less precise measuring methods.  For weight, we use the reliable “back stress test.”  We lift the turtle with the 10-foot net, allowing the full strain to focus on the small of the back.  Yep, 35 pounds.  For shell length, we prefer not to hold a measuring tape above the critter’s gaping jaws.  Instead, our sneaker gently laid across its carapace provides the best reading:  really big.

Male Snapping Turtle Ventral Side and Plastron

The 10-foot net pole also allows us to examine, from a healthy distance, the turtle’s plastron and tail, offering a good indicator of its gender.  As we have noted in earlier posts, the smallish plastron of the snapper does not provide adequate protection for all its vulnerable parts; a factor that Turtle Journal believes contributes significantly to its aggressive behavior.

Male Snapper Tail (with Leech on Left Rear Leg)

Nothing says ancient, dinosaur-like creature more eloquently than a snapper’s tail.  You may note that this specimen sports a leech on its left rear leg (see image above).  It’s difficult to describe how challenging it was for us to remove the leech from the snapper’s limb without the snapper removing portions of our limbs.  Still, a reptile’s “gratelessness” is one of the attributes for which we admire them.  No one accused a snapping turtle of bonding with its human rescuer, unless munching is a form of bonding.

Male Snapping Turtle Heading Back Home

After suffering the ignominy of this encounter with humans, the snapper said his fond (sic) adieu and headed back to the depth of his bog.  If you’re looking for an example of determination, you may wish to review the video one more time.

What Lies Beneath … Once Again?

As the snapper plunged into the water and disappeared into the murk, we got one last glimpse of him submerging, “through a glass darkly.”  Bringing us full circle, the question lingered in the air, “What DOES lie beneath these murky waters?”

First Eastern Box Turtle of 2014 Season

Friday, May 2nd, 2014

Male Eastern Box Turtle (Terrapene carolina carolina)

The Turtle Journal team found our first Eastern box turtle (Terrapene carolina carolina) of the 2014 season at noon on Thursday, May 1st, in an upland woods on Outer Cape Cod.  As pictured above peering through the partially closed hinged plastron, the turtle’s bright red eyes confirm his masculine gender.

Eastern Box Turtle #1110 in Wellfleet Woodlands

We had committed to search a wooded upland property off Old Kings Highway in Wellfleet for Eastern box turtles.  As we well know, this spring has been especially chilly and box turtles have remained inactive, lingering in hibernacula, and delaying the timing for this sweep.  Because  the forecast promised temperatures in the upper 50s accompanied by torrential rain, the Turtle Journal team selected Thursday as the first viable opportunity to find box turtles on the site.  And so we did.

Don Lewis Discovers Eastern Box Turtle #1110

As we swept these woodlands, we looked for box turtle “forms,” which are shallow depressions covered by grass, leaves and debris.  We sometimes call these forms “garages” because box turtles “park” themselves inside.  Eastern Box Turtle #1110 had left its most recent form and was lazing in the warm rain, rehydrating after a long, hard winter brumation.  His domed bright yellow shell seemed quite gaudy in contrast to the surrounding pine needles, oak leaves and winter grass.

Sue Wieber Nourse Examines Male Eastern Box Turtle #1110

The turtle proved shy and “boxed” himself up tightly with his hinged plastron.  Still, we could easily identify his gender based on the concavity in his abdominal scutes and confirmed later by his bright red eyes.

Male Eastern Box Turtle #1110 Plastron (Bottom Shell)

Male Eastern Box Turtle #1110’s carapace (top shell) measured 14.9 centimeters (5.9 inches) long and 12.3 centimeters (4.8 inches) wide.  He weighed 571 grams (1.26 pounds).  His girth (bottom to top) measured 6.8 centimeters (2.7 inches) at the hinge.  This hinged plastron provides a survival edge for box turtles when confronting a predator.  The anterior (front) and posterior (back) sections of the plastron swing on the hinge to close up like a sealed box … giving this turtle its common name.

Turtles “Spotlight” Buzzards Bay Earth Day Event

Who’s Examining Whom? (Photo by TJ’s Sue Wieber Nourse)

On Saturday, April 26th, the Buzzards Bay Action Committee (BBAC) held an Earth Day event at the Fairhaven Senior Center on Huttleson Avenue (Route 6) in Fairhaven, Massachusetts.  Environmental, conservation and environmental groups from throughout all SouthCoast communities staffed tables packed with actionable information.  BBAC invited the Turtle Journal team to join the six hour event, and as illustrated by the photograph above, turtles “spotlighted” the day’s activities; spotted turtles, of course.

Adult Female (Top) and Male (Bottom) Spotted Turtles

This spring has been especially chilly.  With the exception of just a handful of diamondback terrapins, snapping turtles and painted turtles, only spotted turtles have been active in the wetlands of the SouthCoast.  We are very fortunate to have such gorgeous little reptiles as our earliest harbingers of spring.  It’s amazing they appear so small and delicate, yet are so hardy in the harsh spring climate.  We recently discovered this couple above at the Goldwitz Bog in a mating aggregation that has been severely degraded by debris dumped into bog channels over the last year ironically in a federally funded project to “improve” wildlife habitat.

Male Spotted Turtle (Clemmys guttata)

After spending the day meeting SouthCoast families and advocating for real wildlife habitat conservation, these handsome spotted turtles, like the adult male pictured above, headed back into wetlands mating aggregations to do their important part to advance the survival of SouthCoast turtles.

Sue Wieber Nourse Examines Four Spotted Turtles on Easter

Temperatures dipped below freezing on Easter morning on the SouthCoast of Massachusetts.  Cold brought quiet to spring activity in local wetlands with a single, lazing garter snake and a pair of spotted turtles our only observations in protected Goldwitz Bog.

Garter Snake at SouthCoast Bog

The young garter snake had sprawled out on the sunny pathway at the abandoned Goldwitz bog and seemed unamused when Turtle Journal’s Don Lewis pulled out his smart phone to snap a few closeups.

Female (Left) and Male (Right) Spotted Turtles

Turtle Journal’s Sue Wieber Nourse found female Spotted Turtle #53 (on the left) relaxing with male Spotted Turtle #118 (on the right).  Pictured above, they represent perfect gender types:  she with her colorful neck and thin tail; he with his drab neck and thick tail.  Male #118 also exhibits concavity across his plastron’s abdominal scutes, while Female #53 shows off her flat, washboard abs.  They, too, were found in a degraded mating aggregation at Goldwitz bog.

Male Spotted Turtle #120

About a mile away the Turtle Journal team explored the Grassi Bog around noon on Easter as temperatures climbed into the mid-50s.  At this wetlands we discovered spotted turtles in full mating glory.  Seen above is male Spotted Turtle #120.  He hit the scales at 188 grams (6.6 ounces) and his carapace (top shell) measured 11.43 centimeters (4.5 inches).  For our spotted turtles, he’s a very big boy!

Female Spotted Turtle #121

We also netted female Spotted Turtle #121, an 11-year-old that weighed 185 grams (6.5 ounces).  Her shell length measured 10.56 centimeters (4.2 inches).

Female Spotted Turtle #122

Female Spotted Turtle #122 is only nine years old.  She weighed 115 grams (4.1 ounces) and measured 9.61 centimeters (3.8 inches).

Young Five-Year-Old Female Spotted Turtle #123

The real sweetheart of the bunch is young Spotted Turtle #123, a five year old female.  She only registered 64 grams (2.3 ounces).  Her carapace (top shell) measured a mere 7.18 centimeters (2.8 inches).

Sue Wieber Nourse Release Spotted Turtles

After we examined the turtles and took scientific measurements, Sue Wieber Nourse released the spotted turtles back into Grassi Bog.

Two-Year-Old Painted Turtle

The Turtle Journal team also found a juvenile (2-year-old) painted turtle basking in some brambles at Grassi Bog.  No Easter bouquet could be complete without a baby painted turtle to add a dash of color to the day.
