When you run across a bit of danger…

There’s nothing like leaping branch to branch through in a tree. Sometimes Hickory and I feel we’re flying like the birds, we move so fast.

Then you come upon something that really makes you think I need to watch where I’m going!

Paper Wasps building a nest

Yep, paper wasps. Building a new nest. Luckily, we had swerved to avoid the wild rose tangle they were in and missed leaping into them. Also luckily, this was a tiny piece of new nest, with not many wasps around. This late in the summer, that means a nest broke in a storm.

“Or did the hive split and these ones are establishing with a new queen?” Hickory  asks with a twitch of his tail.

Well, we didn’t stick around to learn the answer.

Bluebird Nestbox Invaded

Well, this is a hard story to tell, folks. Our reader friend, Nancy, wrote that the Eastern Bluebirds in her yard had laid a second set of eggs.

They hatched, but twelve days later the parent birds were forced to abandon the nestlings.

Note: Nancy began documenting this local bluebird nesting and shared it with The Squirrel Nutwork in April. Search ‘bluebird’ if you wish to see the older posts!

First, we are pleased to say the fledglings from the first nesting  had continued to stay with the parent bluebirds, and were helping to feed the second set of hatchlings.

Nancy reported it was wonderful to see all three return.

Then one evening a raccoon tried to get into the nest box…

…including climbing the nearby fence. Lucky for the bluebirds, he got stuck and gave up.

But the next day, a House Sparrow was spotted entering the nest box. You readers may remember that the House Sparrow entered the nest box after the first set of fledglings left.

These aggressive–and non-native!–birds must have been harassing the bluebirds all along. Despite the help from another male bluebird and the three juveniles, the female was looking thin and worn out the day the raccoon appeared.

All of the bluebirds disappeared, leaving the 12 day old nestlings.

Nancy and her family tried to feed them.

Feeding bluebird hatchlings

Mealworms, egg whites and soaked dog food were recommended by the Wildlife Rescue League–but with work, these humans couldn’t feed the same amount of food that six birds could, and the nestlings didn’t make it. Nancy and her family were quite upset when they wrote us.

As soon as the nest box was empty, a House Wren tried to use it, and in fact, was rather insistent!

The solution has been to leave it open to discourage the other birds.

Unfortunately, this nature story isn’t unusual. Even with this much help from humans, wildlife have a tough time of it. The competition for food and nesting sites is fierce. The more docile songbirds like the Eastern Bluebirds can’t compete with critters who are more aggressive.

Nancy wrote us that even with the loss of the second hatchlings, the positive part of having the nest box in their yard was the success of the parent birds raising the first three chicks through to being able to fend for themselves. They will go on to raise families of their own next year.

A Bluebird Update

Our reader friend Nancy has sent us an update on the Eastern Bluebirds making their home in her suburban Virginia yard.

The parent birds have been dutifully hunting insects. But while they were away one afternoon, a Gray Catbird took to hanging out on the nest box…

The hatchlings were all accounted for. Thank you, Nancy, for the pictorial update!

X is for X-tra special bird on Thirsty Thursday

Ol’ Wally here knows you humans will be thrilled to hear that we squirrels periodically see this frightening bird. Right here in Reston.

Bald Eagle

Bald Eagles hold some sort of celebrity status with you humans, and though we know they are probably hunting fish in the golf course ponds–not squirrels in the woodlands–seeing the shadow of this big bird of prey is downright unnerving. Lucky for us, they like bigger streams and lakes, ones farther from us. The older birds, the ones who appear to be bald because their head feathers are white, have laid claim to territory along our area’s best waterways, like the Potomac River.

Still, for our readers, we will feature them. After all, X is a mighty hard letter to come up with something for in nature…especially related to water…unless you consider xylem, the passages in trees that transport water from the roots to the leaves…but Nutmeg hasn’t figured out how to photograph that.

One of Nature’s Mysteries to Solve

Hey there,

This may not be a difficult mystery for some of you, but it’s an important one.

Mystery #107

What is this plant with the attractive fall foliage?

~~~

So we had a few readers who recognize this as Poison Ivy. See the leaves of three? Gorgeous color, isn’t it? But the oil that causes rashes still remains, in the leaves, in the stems, the berries and even the roots. It’s not a good idea to touch Poison Ivy in any form, in any season!

Visitor!

Hickory is twitching his tail something fierce! A hawk flew into one of his favorite feeding stations and had an accident. He flew into the human’s window.

While we sat frozen behind other leaves, the hawk wavered. Then he flopped to a branch.

“What’s he doing?” Hickory hissed.

Sitting, I guess. It’s a Cooper’s Hawk, not very old, this year’s hatch.

“But that’s my branch!”

Do you really want to go over and tell him that?

Hickory started to chitter and stopped when the hawk turned our way. “No. Let’s go.” But before we could, the hawk raised his wings and flew off…and seconds later Hickory let loose with his chittering. I ran off to hide. No way was I going to attract a hawk, even a young one.

Fall is mushroom sprouting time

The rain is bringing out the ‘srooms!

Mushroom

We don’t know what this one is exactly, but Miz Flora thinks the little extra flap of white around the stem means it’s poisonous. We caution you human readers not to handle or eat any wild mushrooms. Just have a look at how cool they are.

Hey there,

It’s the last Sunday off for good behavior in the Blogging A to Z Challenge. Take a gander at the website, if you haven’t done so yet in April, and hop to some of the other blogs. If you’re into science, look for the ones with a ‘SC’ after their names.

And on to today’s mystery!

Mystery #87

You’re leaping along through the woods and come across a patch of these red leaves. What are they?

 

Back later for your guesses and the answer!

~~~

As one of our regular readers guessed, this plant is poison ivy!

Poison Ivy

The new leaves emerge red tinged, changing to a shiny green in a week as they grow to full size. Here, and in may  woodsy places around the east, the vines are traveling underground and sending up new shoots–everywhere! The oil in the leaves only seem to affect bare skin, not fur, like we squirrels have. But as many of you readers may have discovered, the oil can transfer from fur–ours or a dog’s–to bare skin and cause an allergic eruption.

So beware! If you see this red blush over the ground the spring, change your route! And encourage your dog to do the same.

By the way, if the vine you are seeing has five leaves, it’s Virginia Creeper. Leap back to some of our very popular posts on this other native vine, here.
