We squirrels are leaping from dry branch to dry branch that we are finally out of the rain! Time to enjoy the sun!
But watch out for those streams that are filled to the brim!
For today’s mystery, I’m asking if you know what kind of turtle this is?
I’ll check back later for your answers!
We’ve had a few correct guesses, so I decided to pop in and confirm that the turtles are Red-eared Sliders. That red mark along the side of the head is quite distinctive, as is their ability to ‘slide’ into the water when danger approaches.
Red-eared sliders are now a common turtle in ponds even outside their normal range, and are considered invasive. Unfortunately, this is because many have escaped or been let go as pets. They eat both plants and animals in the water, preferring still water of ponds, but also slow-moving streams and rivers. With high numbers and more rugged ability to adapt, the red-eared sliders replace shyer, native turtles and might be one of the reasons frogs are on the decline.
The warm, sunny days of spring have brought up the Eastern Painted Turtles from their hibernation in the pond mud. Even if it cools down again–like it has here in Virginia–the turtles will be okay. They have a anti-freeze-like blood that sees them through these temperature changes.
What better ‘E’ wildlife to feature on our normal ‘water’ day, Thirsty Thursday!
Our mystery today comes to us from regular reader, Connie. Thanks, Connie!
Yes, it’s those little blobs, about the size of a small acorn.
I’ll check back later for your guesses, but if you’d like a hint, scroll down:
Hint: Connie found these on her pontoon boat.
One brave reader guessed that these particles were the stuffing from the boat. No, but that was our first guess, too! No mice or insects were burrowing inside. This was deposited on the boat and appears nearly every morning, Connie tells us.
And every morning someone visits the boat.
If the light is a bit too dim for you, here’s another photo.
That’s a Great Blue Heron. A very old one, we believe, because his beard–the feathers trailing from his neck–is full. Now we squirrels had heard of owls regurgitating pellets of fur and bones after they eat, but not herons, so we did a bit of research. Turns out herons do as well, and it’s called “casting.”
If you look closely, this deposit, or regurgitation, contains small fish bones and scales!
Herons also have a throat pouch. When they have young in the nest, they swallow a fish or two and carry them back to the nest and regurgitate them for the young birds. Young birds might do the same if a predator attacks their nest to frighten it away.
