Thirsty Thursday

Folks, it’s been dry this fall. But this old squirrel, with his comfortable suburban life knowing which houses have a birdbath or backyard pond the humans keep filled, had no idea the local natural waterways were faring this poorly.

Yikes, that is low for our local pond.

We haven’t had a freeze–ha, far from it!–so the place was still abuzz with insects, like this male Autumn Meadowhawk.

Despite finding the pond in less than its best state, I’m happy I took the outing while our weather is balmy.

One of Nature’s Mysteries to Solve

Hey there!

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.

E is for Eastern Painted Turtle

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!

Hey there!

Our mystery today comes to us from regular reader, Connie. Thanks, Connie!

Mystery #179

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.

Great Blue Heron on Lake Audubon

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.

Want to learn more about Great Blue Herons? The Cornell Lab of Ornithology has a camera on a heron nest and answers many questions about these birds on their Bird Cam FAQ website.

Walk around a pond and you’re sure to see dragonflies. Have you folks ever noticed some of them eat the smaller damselflies? Dragonflies are predators! Reminds this old squirrel of a miniature hawk.

DSCN2441This here is a favorite of mine, the Eastern Pondhawk–see, Ol’ Wally isn’t the only one thinking hawk! The male is easy to identify if you look for the blue abdomen and green face.
