Folks, our natural world is a great place! We hope you can get outside to enjoy it today.
Happy Thanksgiving from all of us at The Squirrel Nutwork!
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.
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.
I’m sure you’ll be watching over your shoulder on your next pond stroll!
Down at the pond, there are a lot of insects flying on these long summer days. When its hot, this old squirrel likes to take a slow meander down to the edge and stretch out in the shade of a big tree.
Well, today, from my sycamore branch, my whiskers were buzzed by a damselfly. Don’t know if you good human readers have ever had that happen, but it’s annoying. The darned thing forced Ol’ Wally here to open his eyes.
Before me was the prettiest little blue damselfly–an Ebony Jeweling. This one was a female.
I watched. Sure enough, in a few minutes along came a male.
They’re easy to tell apart–he has white patches at the tips of his wings.
These aquatic insects are sometime called black-winged damselfly. Easy to tell why.
Well, it wasn’t long before they found each other, and started doing what bugs do.
That’s why there are so many of them around in nature. I closed my eyes–not out of modesty, but to go back to sleep. They’d forgotten about my whiskers.
Ol’ Wally here was headed down to the local pond to cool off when I saw a gathering under a tree.
I bounded a bit closer…then decided I best not.
Geese. Canada Geese. Normally not an issue, but these adults were protecting little ones.
And a goose with goslings–watch out, humans and beasts! However…these geese weren’t doing more than looking my direction…
could it be they were just as hot as I was?
Well folks, this old squirrel thinks it’s hot… and look who else agrees with Ol’ Wally!
The fish are even seeking out the shade.
Had a nice visit to a local pond this week. I know you humans are seeing a lot of birds here on The Squirrel Nutwork, but they are a bit busy this time of year, and it’s not different down at the ponds.
Thought you might like this Spotted Sandpiper–I suppose a muddy shoreline inland holds just as many bugs as a muddy marsh edge.
But I daresay we have prettier flowers around here.
The Wild Lupines, Lupinus perennis, grow big and lush with their roots getting proper water. While looking this one up for me, Miz Flora discovered my comment on that was rather ironic–lupines like poor sandy soil, in either part shade or sun. Doesn’t sound like our Virginia clays would be much good, but next time I’m over that way I’ll dig around a bit and see if this was a gravelly patch.
Ol’ Wally was surprised to learn the Wild Lupine is the ONLY food eaten by the Karner Blue butterfly caterpillar. (As you might guess, this is a small blue butterfly–here’s the U.S. Fish and Wildlife Service Fact Sheet on the Karner Blue butterfly.) Huh, poor little guy. He’s on the endangered species list. We don’t see too many lupines around. Perhaps you humans would like to give a few a home in your garden?
