new logs, floating in the pond

 

The painted turtle Chrysemys picta is a native in Minnesota and of North America.

Painted turtles are active only during the day; they are warmed by their surroundings on sunny days by basking for hours on logs or rocks.  On cloudy days or at night the turtle drops to the bottom of the pond.  Painted Turtles eat aquatic vegetation, algae, and small water creatures including insects and crustaceans.  They primarily feed while in water and are able to locate and subdue prey even in heavily clouded conditions.

cruising on a log

 Painted Turtles line up on the shore to soak up the sun.

The free-floating log in the pond is a wonderful chance for the turtles to take a cruise, even though everything is covered with algae.

floating log

 We tied a weight to a driftwood log, and put it offshore for the turtles to sun themselves.  There are several logs partly on the shore but this one turns with the breeze and flow of water.

Sure enough, one turtle made its way to the log within 60 minutes.

Later, the Hooded Merganser hen stood on it to survey the surroundings from a new angle.

first turtle of Spring

Adult painted turtles Chrysemys picta begin active foraging usually in March or early April.  Since winter has held on strongly until now, we only saw the first turtle today when the sun was shining and temperature is in the 60's F.  

Shortly after awaking from winter, courtship begins.  If they laid clutches of eggs last fall, the little hatched turtles probably over-wintered in the nest.  Now they emerge and instinctively seek the security of water in the pond.

Today, the Spring Peepers are singing too!

turtle tower

Painted Turtles Chrysemys picta of all sizes live in the pond.  They are oval shaped, and the carapace (top)  can be almost black to dark olive green.  The plastron (bottom) varies from red to orange with differing amounts of black patterning.  The older ones are as big as ten inches long, with the females being bigger than males.

These two 10" turtles are starting a 'turtle tower' on their favorite rock.

baby snapping turtle

We found this baby Snapping Turtle on a street curb in the neighborhood. We relocated it to the wetland around the pond, hoping it would find enough to eat there.  Snapping Turtles Chelydra serpentina eat water plants as well as insects, worms, snails, small fish, and anything edible that it can find.

log in snow drift

We call the log near the shore of the pond  'turtle log'.  

Now it is buried in a snow drift.  It is curved, and usually emerges above the water or ice at least 18 inches.

Twenty inches of snow fell on the pond in this one early-winter storm. 

log

 Every pond needs a log for turtles to sit on while sunning themselves.

It will probably be used by birds hunting aquatic prey, damselflies drying their wings, and frogs.

The turtles are practicing balancing rocks today.

Or, the big one coaxed the small one to help it hold a pose. 

gleeful painted turtle

The painted turtles who live in the pond love to sit in the sun, especially on rocks near the water. There, each can enjoy the warmth and (in case of danger) slip into the water to hide if needed. This young little critter, about 4 inches long, looked so gleeful today with its feet extended out to catch as much sunshine as possible.

basking turtles

Many Painted Turtles Chrysemys picta live in the pond. On sunny days they climb out of the water and bask in the sun to warm their blood.  In this temperate Spring weather, they spread all their appendages including head and neck out of the shell to get maximum exposure.

turtles in Spring

Springtime, sunny, and balmy.  Turtles all came out of the pond today to warm up on the rocks. To get maximum exposure to the sun's warmth, they extend their legs, neck, and tail.

surviving below freezing - turtles

Since we had several cold days and nights already, Painted Turtles Chrysemys picta who live in the pond are getting ready for winter.  Lacking summer heat, this one was wandering very very slowly for a food item or a place to settle. Turtles will spend the next several months in frigid pond water below the frozen ice, with their metabolism and their heart rate slowed way down. They can absorb oxygen from the water through vascularized areas in their mouth, throat, and anus (cloacal respiration).  But using oxygen produces lactic acid in their body, which the turtle counteracts with minerals released from its shell and bones.  Painted Turtles do not eat during this time, but they do remain alert, especially to light from above.  In Spring, when the hours of daylight increase, they will respond.

balanced turtle

This turtle was probably thinking it could be the top part of a balanced rock sculpture.  Or, maybe seeking a sunny rock and believed this would be it.  Not enough rocks for a sculpture, nor the right shape to be comfortable!

turtle munching

The pond was quiet and clear today, after a rain shower overnight.  We could see to the mud, sand, and rocks on the bottom. 

A Painted Turtle Chrysemys picta was very visible in the water, looking for lunch.  Painted turtles feed mainly on aquatic vegetation, algae, small water insects, dragonfly larvae, crustaceans, plants like water lily or duckweed, and sometimes dead or injured fish.  

When this turtle bumped into a floating mass of algae or plant matter, it was lunch time!

birds on the branch

Eastern Bluebirds also like to sit on the branch over the pond.

Many flying creatures use this branch as a place to spot a prey item to eat, or a place to rest, or a place to socialize.

In this photo, after some rain, the rock behind the Bluebirds is under water.  It is our gauge for the water level in the pond.

Below, a turtle sits on the same rock on a day when the water level is lower.

high water

This morning, after
7 inches of rain fell overnight, the pond is higher than usual and some of the shoreline around it is under water.  The critters are trying to find their favorite places to feed or soak up the sun.


I was watching a turtle crawl slowly up on a small rise among the grasses.


Then a frog croaked, and I noticed him right near the turtle.  We've been hearing these Green Frogs
Rana (Aquarana) clamitans
for several weeks.  They are usually secretive; this is first time I've seen one here.  Do you see him in the photo below?

raided nest

Many Painted Turtles Chrysemys picta live in our pond. They mate once a year; in Minnesota, it is usually late May or June. Usually, Painted Turtles lay between 4 and 15 eggs. This year, the females looked for nest sites with soft sandy soil, even if they have to cross lawns and rocky shores.


One found a good spot on the sunny slope above the pond. Because she knows her hatchlings will instinctively head straight for the water, from here their short trip will be downhill.  She dug a shallow hole with her hind feet, and deposited her eggs.  She covered the hole carefully and returned to the water, her job done for this season.

The eggs usually hatch about 72 days later, in late August or early September.  Unfortunately, turtle nests are often discovered by birds, raccoons or skunks, who make a meal of the eggs.  It's not unusual for many of painted turtle eggs to be lost to predators.  We found a few raided turtle egg nests like this one . . .  the eggs eaten and the shells strewn around the hole.
