The Science Behind Fledging Birds

TOS_grouse_fledglingOn a recent afternoon, I saw a baby ruffed grouse about the size of a pin cushion scurry into the bushes. I had the same impulse I did as a 10-year-old when I scooped up a baby blue jay hopping around on a neighbor’s lawn: I wanted to “rescue” it.  Instead, I kept driving, leaving the tiny bird to its fate.

Fledging is perilous for all birds – most won’t survive their first year – but what exactly is that process? Do nestlings know when to leave or do the parents signal when it’s time? Do they all go at once? Will the parents continue to protect and feed them after they have fledged? And what should I have done, if anything, to help that baby ruffed grouse? » Continue Reading.

Climate Change is Altering Nature’s Clock

Salamander-Stager-600x383Scientist Curt Stager walks along the edge of the woods, his flashlight shining into the shallow water of a leafy, roadside pool on a dark night in Paul Smiths. It’s late April, and he’s out looking for spotted salamanders, wood frogs, and spring peepers that have migrated to shallow vernal pools to breed. After poking around for a minute, he lets out an excited shout: “There’s a salamander! There he is! He’s early!”

In the water is a dark, four-inch-long creature with bright yellow spots. In the same pool not far away, wood frogs float on the surface. In another week, pools like this will be a filled with breeding frogs and salamanders, which will leave behind egg sacks that hatch into larvae.

Spotted salamanders spend most of the year underground, so seeing them is rare except during these annual breeding migrations. Their journeys are triggered by the first rains of spring. » Continue Reading.

Adirondack Moose Population Showing Positive Signs

July 2012 at Helldiver Pond, Moose River Plains (Linda Bohrer Erion photo)The Adirondack moose population appears to be healthy and growing, according to early indications from a moose study currently taking place.

“We don’t know how many moose we have yet. We don’t know how frequent the moose are on the landscape. We don’t know their densities,” said Ben Tabor, a wildlife biologist with the state Department of Environmental Conservation. “What we do know is that our moose seem to be bigger and healthier than New Hampshire’s and Maine’s.” » Continue Reading.

Carry Firewood Now, Boil Less Water Later

Fire Wood by John WarrenHow much are you willing to pay to boil water? I don’t mean to make coffee or cook pasta, but for the heck of it. Would you spend $200 to $600 annually just to let off some steam?

Probably not, right? But if you heat with wood, you already shell out hard-earned money each year to boil water for no practical reason. » Continue Reading.

Trees: Understanding Roots And Root Care

PaulHetzlerTreeRootAngelaPerry4002.5April showers bring May flowers, the calls of spring peeper frogs, and of course, backhoes. Yes, it’s construction season, which for arborists and trees is also root-damage season.

As far as trees are concerned, root injury is the source of all evil. Well, most of it, anyway; chainsaws and forest fires aren’t so kind to trees, either. But regardless of the worrisome signs a tree may develop, whether early fall leaf color, tip dieback, slow growth, or even some diseases and insect infestations, the problem is below ground in the majority of cases. » Continue Reading.

Going With the Flow: The Sixth Sense of Fish

TOS_NeuromastThere are times when fish appear telepathic. Consider the uncanny way a school of bait fish moves as one to avoid a predator, or the way goldfish in their lighted bowl turn towards the glass when someone walks into a dark room.

Researchers often describe this ability as “touch-from-a-distance.” But fishy sixth sense is closer to hearing than touch. It’s what allows salmon to deftly ply the currents and eddies as they make their spawning runs upstream. They listen to the flow. » Continue Reading.

A Late Maple Sap Run For Syrup Makers

Sugar Shack 2015In spite of deep snow and frigid temps through early 2015, most maple producers in northern New York have been ready for sugaring season since early February, but they had to wait for the right weather to trigger sap flow.

Until this past week, sap runs in the region had for the most part been sporadic and brief, and producers at higher elevations where it is a bit colder have seen very little action until now. » Continue Reading.

Identifying Trees In Winter Using Buds

Tree BudsEvery winter I teach several tree identification classes to biology students. Cold or colder, it’s always outdoors, but if student evaluations are on the level, it’s always fun. Demonstrating how to tell one leaf-bereft hardwood from another is one thing.

Bark is not the best feature for identifying trees. Sure, white bark means birch, but some birches have black, yellow or reddish bark. Typical bark patterns, such as diamond-shaped furrows for ash, can be absent depending on site conditions and tree health. Cherry and ironwood bark have light-colored horizontal dashes called lenticels, but only on young wood. Not all hickories have shaggy bark. Bark may provide a clue, but it’s not to be trusted as a sole, or even a primary, source of information. » Continue Reading.

Carthage Inventor Edward Shortt (Conclusion)

02ShorttDuplexEngineTwo creations of Jefferson County’s Edward Shortt were very successful in the 1880s, but like most inventors, he was always thinking, always innovating. Commercial success was important for funding future projects, but his steam pump and award-winning duplex engine, along with the backing of wealthy men like Charles Emery, ensured Edward of a comfortable living standard.

In the early 1990s, as Shortt’s duplex engines began mass production, he delved into designing a better braking system for trains. Other than for financial profit, there were many reasons to do so. Frequent and horrible rail accidents involved great loss of life, particularly in collision situations. The inability to effectively slow and stop such large, moving vehicles often played a role in catastrophic crashes. » Continue Reading.

Adirondack Snowshoe Hares in Winter

TOS_HareHomeFor the past 14 years, my Winter Ecology students and I have spent a lot of time outdoors, studying the preferred habitat features and winter foods of snowshoe hares. We’re likely to find hare tracks hopping in and around lowland conifers near wetland edges, and then again at higher elevations, where the forest transitions into fir, birch, and spruce. Where we won’t find them, at least not very often, is in broad bands of open, leafless hardwood. On the rare occasions that we find tracks in this habitat, they have almost always been single strands of widely spaced prints – suggesting an animal that’s really moving! » Continue Reading.
