As the summer bird chorus wanes, we might remember that song can arrive in unexpected ways. Drumming heads, clacking bills, and dancing feet create nonvocal sound. Even flight, that foremost avian feat, creates music of its own.
Wings can sing – sound is created by the asymmetry, anatomy, and arrangement of individual flight feathers as they vibrate through the air. A number of birds use wing song to communicate, both with their own species and as a way to thwart predators. » Continue Reading.
On the lower levels of the food chain, danger is rarely out of spitting distance. Risk from predators has spurred the evolution of many clever adaptations – camouflage coloring, speedy retreat, distasteful secretions, and armor plating among them. Small jumping insects known as froghoppers approach concealment in a unique way: their developing nymphs cover themselves in a bubble bath. From this trick they derive their common name, “spittle bug.”
If you investigate the clumps of white froth, sometimes referred to as ‘cow spit’ or ‘frog spit,’ that appear on plant stems this time of year, you’ll find that each dollop of foam envelops a soft, greenish insect. Who would have thought that froth, so soft and insubstantial, could be protective? Yet predators can’t see the bug for the bubbles, and if they probe the foam, they soon find that it has an acrid taste. The spittle bug’s foam is also a good insulator against heat and cold. And it is a great moisturizer, without which the soft-bodied nymph would soon dry up. » Continue Reading.
Last week my eight-year-old nephew, Romeo, got on an animals kick. He’s an inquisitive kid who’s fascinated by things like white blood cells and he absolutely loves sharks. So, knowing that I was some sort of fish doctor, he made his fifty-seventh inquiry in what I learned was to be a series of 2000 questions, “what are the strongest animals in the water?”
“Mussels,” I replied. My nephew’s eyebrows scrunched in mild displeasure (sort of like yours are now) because the joke was borderline funny, barely punny and the opposite of true. Regardless, I had an opening to use some new-found knowledge about the dwarf wedgemussel, Alasmidonta heterodon, so I forged ahead. » Continue Reading.
Some catch their prey while in flight; others sit and wait for prey to come near. They’re a group of birds known as aerial insectivores, and they’re in trouble. In the northeast region, this diverse group consists of 19 species that, as their name implies, feed almost exclusively on flying insects. Some, such as the barn swallow and eastern phoebe, are quite common and well-known, while others, such as the olive-sided flycatcher and eastern wood-pewee, are relatively unknown to non-birders.
Unfortunately, as a group, aerial insectivores have been declining steadily across northeastern North America for the last 25 years or so. Flycatchers, swallows, and nightjars (the whip-poor-will and common nighthawk) have been particularly affected. » Continue Reading.
What follows is a guest essay by Connie Prickett, Director of Communications for The Nature Conservancy’s Adirondack Chapter. The Nature Conservancy is using $500,000 to create a new grant opportunity for recreation-based development in local communities.
When The Nature Conservancy in 2007 took on its largest single land conservation project in the Adirondacks, we knew success was only going to happen through collaboration. Recent steps by the Conservancy to establish a $500,000 grant opportunity ensures that community involvement continues to be an integral part of the conservation equation and a key element to the project’s overall success. The aim is to help communities position themselves to capitalize on new outdoor recreation opportunities being created through this project. » Continue Reading.
Aldo Leopold, the famous conservationist, once wrote: “One of the penalties of an ecological education is that one lives alone in a world of wounds.” This whole idea puts nature writers in an odd position. On the one hand, it’s our job to raise the alarm when we see something amiss, but on the other, we run the risk of spending so much time dwelling on nature’s wounds that we end up giving people the impression that everything has gone to hell, which of course it has not.
So what to make of earthworms? We’ve been told for years that worms are good. Darwin was a great admirer. They make our gardens grow. But as invasive plant and animal awareness grows, we’re now being told they’re invasive animals that have the potential to destroy whole forest ecosystems. » Continue Reading.
Let’s start out with a riddle: What animal has 16 toes and a tail that breaks off when grabbed by a predator? Not sure? Here’s another clue: It’s the smallest terrestrial vertebrate in our area. If you didn’t guess four-toed salamander, don’t feel bad—it’s probably also the least-known salamander in the North Country.
The four-toed salamander (Hemidactylium scutatum) holds a number of dubious distinctions. Besides its diminutive size (a typical adult may only reach 2-3 inches in length), it is also the only terrestrial salamander with four toes on all four feet. With the exception of the aquatic mudpuppy (which happens to be our largest salamander), all other salamanders have five toes on their hind feet. Four-toeds also have specialized breeding habitat requirements, which probably accounts for their limited distributions in our region. Combine that with their small size and cryptic behavior, and you have a recipe for an animal that very few people have ever heard of, let alone encountered. » Continue Reading.
When I was ten, I carried a tin can of worms and a battered fishing rod to the wild shores of Brickyard Pond, in the woods behind our subdivision. We caught mostly scrappy sunfish and white perch, with the occasional bass thrown in. There were alewives in some of the brooks, too, and we caught them with nets. As for the pretty trout that came from the hatchery truck, I never caught one. The fish I caught were mostly round, dark green or gray, and mottled like the mud and sand bottom of the pond.
Then one day a friend’s older brother, a real fisherman with a green fishing vest, caught a large brown trout. I couldn’t believe my eyes. The fish, shaped like a torpedo, was a yellowish gold and it had big red spots on its sides. Years later, I caught my first brook trout on a fly rod at Shoal Pond in the White Mountains. Again, I was mesmerized by the intense colors: the yellow and red spots, some with bluish halos, the fins that were bright red with white and black trim.
It all begs the question: why the trout’s fancy colors when so many other fish are dishwater dull? » Continue Reading.
Twenty years ago when I bought my farm I made a snap decision to clear some woods near the house, all the way back to the stone wall. Out came the chainsaw and trees started crashing down.
I never did finish “neatening up” that section of the fence line. And it was only later that I realized that I had turned the only sizable northern red oak on the entire 40-acre woodlot into firewood. As a guy who prizes forest diversity, I was chagrined. No help for it. Except, a few years later I noticed some healthy sprouts from that oak stump. I left them alone. Now the three biggest are six to eight inches in diameter and some forty feet tall. » Continue Reading.
In early summer, my roses are buzzing with bees. European honeybees from my hives are tripping over the tiny metallic native bees while burly black and yellow bumblebees, the sumo wrestlers in this ring, shoulder through the stamens.
It would appear all is right with bees. But it’s not. Everyone knows honeybees are in trouble, but bumblebees are also in worldwide decline. In North America, several species are extinct, or perilously close to it. » Continue Reading.
In years when the snow is deep, voles, the most abundant mammal in the Northeast, thrive. When the snow recedes, the glaring white of rodent-chewed bark shows up on saplings along field edges, roadsides, and, especially, in orchards.
In addition to bark, meadow voles will eat almost every agricultural crop. When, as sometimes happens, there are thousands of these metabolically active animals per acre, the damage can be significant, even though each one weighs just an ounce or two. » Continue Reading.
In the natural world predation is relentless, and evading predators strongly favors the evolution of camouflage colors in animals. How contradictory then, for small, defenseless creatures – like red efts and monarch butterflies – to be sporting a bright shade of orange. But there is more to their cheerful color than meets the eye. Both the eft and the monarch are poisonous.
Once a predator has tasted one, it soon gets sick, and from that experience learns not to eat another. Thus an individual eft or butterfly may sacrifice itself, but the education of predators benefits the species as a whole. And, in fact, efts and monarchs often survive predator attacks. Toads and snakes that swallow red efts have been observed to vomit up the prey unharmed in about half an hour. Birds that attack monarch butterflies often go for the brightly colored wings, the most toxic part of the insect. One peck may be all it takes to deter the bird. » Continue Reading.
We all see our forests for the trees, but the woods are alive with other plants. Among the most common are ferns, which don’t just get by in the deep shade of the forest – they flourish.
Now, you might be thinking, don’t all those ferns look alike? They form a lovely verdant backdrop to the forest, but they don’t have the showy flowers and distinctive leaves that make other plants so easy to identify. But ferns are surprisingly easy to tell apart. And once you know the names of a few species, they’ll pop out at you as you wander along forest paths. » Continue Reading.
One of my hobbies this time of year is to try to pinpoint the day that I can say that the leaves are out and spring has arrived. Usually it’s sometime in the second week of May, though it seems to have been inching forward over the past couple of decades. But even when I can declare that it’s “spring,” not every tree is clothed in green.
Ash trees, for instance, will still have bare branches weeks from now, and the northern catalpa in my yard will balk at putting out its saucer-sized leaves for another month. Why? The question has gnawed at me and, I’ve learned, bedeviled scientists for decades.
