Now you see it, now you don’t: something brown in or near the water, hopping, swimming, or doing something else that catches your eye. The suspect list includes mink, muskrat, beaver, and otter. Listen here as I discuss what to look for and how to tell the difference in this week’s edition of All Things Natural with Ed Kanze.

I’m always entranced watching the hunting behavior of long-legged wading birds like great blue herons and snowy egrets. They stand motionless for long minutes at the edge of a pond or swamp, waiting for prey to swim within striking distance. It’s a technique sometimes described as stalking, and it convinces me that those birds have far more patience than I do. I would go hungry if I were restricted to that strategy, since I get antsy after just a few seconds of standing motionless. I’m much more like the reddish egret of the Florida coastline, running around in knee-deep water with wings outstretched, chasing my meal rather than waiting for it to come to me.
Green herons have a hunting technique that involves neither pure stalking, nor the kinetic approach of the reddish egret. They are one of only a handful of North American bird species that are known to use tools to capture food. » Continue Reading.
The overwhelming abundance of pesky insects in and around aquatic areas in the Adirondacks from late spring through mid summer can discourage travel to these picturesque settings, however, the hordes of bothersome bugs that thrive in wetlands help support the rich diversity of life that occurs around these places.
Among the birds that seek out mosquito, black fly, and deer fly infested streams, swamps and shrubby lake shores is a common and vocal warbler whose voice regularly echoes across these watery habitats. Despite its small size and effective protective coloration, the common yellowthroat (Geothlypis trichas) can be seen by anyone passing through its domain as it bellows out its characteristic song from a perch that temporarily makes this Adirondack resident fairly conspicuous. » Continue Reading.
Around a beaver pond, we sometimes catch a whiff of beaver odor. People have described it to me as smoky, woody, or like tobacco. It may waft over from the lodge, or it might emanate from scent mounds – little piles of mud by the water’s edge. Beavers make scent mounds by dredging up mud from the bottom of a pond, then carrying it up on land in their front paws while walking upright. The beaver drops the mud, then squats over the mound and applies castoreum from glands near the base of the tail.
The smell means: keep away! In some neighborhoods, this territorial advertisement works remarkably well. I’ve been involved in studies where human-made scent mounds effectively deterred free-ranging beavers from settling in unoccupied beaver habitat. » Continue Reading.
Spring is the time of year when most male birds support their brightest colored plumage. This makes them more attractive to a potential mate for the breeding season, however it also makes them more visible to any human traveling through their domain.
Among the birds far more likely to be seen during spring than at any other time of year is the hooded merganser, a handsome species of waterfowl that commonly resides in the many wooded wetlands scattered across the Park. » Continue Reading.
Clambakes, fried clams, clam diggers, clam shacks ― we usually associate clams with the ocean. You may have also seen freshwater clams in rivers and lakes. But did you know there are clams that live in the woods?
In our region, there are several species of fingernail clam that inhabit vernal pools, the temporary woodland pools where frogs and salamanders lay their eggs in the spring. As temperatures warm and melting snow and rain fill depressions in the forest floor, these small clams, only the size and shape of a child’s fingernail, become active. » Continue Reading.
I attended a recent forum in Albany, Facing the Storm: Preparing for Increased Extreme Weather in Upstate New York, and wanted to pass along some of what I heard, or thought I heard. The event was sponsored by the Nelson A. Rockefeller Institute of Government.
For a forum concerning the impacts of a changing climate the audience was unusually diverse in terms of backgrounds and professions. As a staff member for Adirondack Wild, I was sitting next to a firefighter from a village in Montgomery County. At the next table were other firefighters and emergency personnel in uniform. Across from me were several members of the League of Women Voters. Initially we all wondered if we were in the right meeting. I think by the end we realized what we all have in common. » Continue Reading.
It’s spring. Red-winged blackbirds are calling, chipmunks are foraging and flocks of robins abound. Bending down to smell the first subtle scents of crocuses and daffodils, we give thanks that winter is over. Sometimes, we also take a whiff of skunk cabbage flowers, just for the olfactory shock value.
Skunk cabbage grows throughout the Northeast and Midwest, ranging from North Carolina well up into the northernmost reaches of Quebec. The flower emerges through the snow and ice of March in the understory of wooded swamps, along riverbanks, lakeshores, and in other habitats with rich wet soils. First growth is an exotic, crimson-hued, three to six inch tall cowl –called a spathe – that surrounds and protects a spherical cluster of flowers. Each flower measures ¾-inch across and consists of 50 to 100 tightly packed florets. » Continue Reading.
Imagine that you are walking on a path through a forest in the Adirondacks and suddenly, you see an opening in the trees ahead. Moving closer, you gaze out on a vast opening covered in a mosaic of leafy shrubs and dotted with spiky conifers. You take a step further and feel the “squish” as your boot sinks into a wet, dense mat of bright green moss. From the top of a nearby snag, you hear the distinctive “quick-three-beers” song of an Olive-sided Flycatcher followed by the complex, jumbled, slightly metallic sound of a Lincoln’s Sparrow. Looking down again, you notice the pale, delicate flowers of a white-fringed orchid. All the sights and sounds are conclusive: you have entered the Adirondack boreal.
The term “boreal” is used to describe cold, wet areas in northern latitudes. For the most part, people think of northern Canada and Eurasia, with vast spruce-fir forests, extensive wetland complexes, and frigid winter conditions. Though much of the Adirondack Park is within the temperate deciduous bioclimatic zone, we can also find low-elevation boreal pockets containing bog rosemary, pod-grass, tamarack and other boreal plants. » Continue Reading.
The Adirondack Park Agency (APA) is seeking public comment on two new general permits related to wetlands in the Adirondack Park that would expedite APA approval for qualifying activities. One relates to the the management of invasive species within 100 feet of a wetland, the other to access and replacement of power poles in wetlands. Both General Permits will apply throughout the Adirondack Park and will be effective for three years unless revoked or modified by the Agency.
The APA will accept public comments until March 28, 2014. If there is significant concern with, or opposition to these General Permits, a public hearing may be required. Approval of a General Permit by the Agency is a SEQRA, Type 1 action. A negative declaration and Full Environmental Assessment Form has been prepared by the Agency and is on file at its offices in Ray Brook, New York. » Continue Reading.
With this winter shaping up to be a cold one, spring may still seem far away. But with time and a little patience, we will soon start to notice the lilac leaves bursting from buds, the return of brightly colored warblers, and the ringing chorus of spring peepers in the evening. Any time you detect events unfolding in the natural world, you are making phenological observations.
Phenology refers to the study of the timing of biological activities. Perhaps unsurprisingly, many of these changes in the life cycles of plants and animals coincide with the seasons. Besides day length, factors that influence the timing of biological events include temperature, precipitation, snowpack formation and melting, and wind. » Continue Reading.
When Tropical Storm Irene damaged Marcy Dam, draining most of the pond behind it, hikers debated passionately whether the dam should be rebuilt to restore an iconic vista enjoyed by tens of thousands of visitors over the years.
It looks like it won’t be.
The state Department of Environmental Conservation recently decided to dismantle the wooden dam in stages over the next five years.
DEC spokesman David Winchell said the cost of rebuilding the dam to modern standards would have been too costly and may have conflicted with the management principles for the High Peaks Wilderness Area. Those principles seek to minimize the presence of man-made structures. » Continue Reading.
The recent round of snow, ice and rain has provided a good opportunity to see the winter performance of the porous pavement used at the newly reconstructed Beach Road, on Lake George. In the last few days we’ve seen lots of black ice and freezing rain, but the porous pavement has been clear.
This road project is one of the biggest experiments in the northeast in stormwater management, but many also believed it will provide better winter driving conditions too. » Continue Reading.
I might have abandoned the idea of reaching South Pond had I not caught a glimpse of it through the trees, right at that critical moment of decision. There it was, right there at the foot of the mountain, a snowy white expanse about a quarter mile away, a remote and lonely retreat with a siren call I could not refuse. Not when I was this close.
I became resolved to continue forward—even though it had taken a full two hours just to come this short distance, and Lexie and I still had the trip back over the mountain to face, too. We had taken our time dealing with the thickets of tangled spruce and the isolated deadfalls that had been dogging us all the way up and over the mountain, one after the other. There had not been much clear walking. Ironically, near the bottom of the mountain we began to encounter a new obstacle: small but steep ledges that again forced us to adjust our course and find yet another way around. Not once since we had started up the mountain had we been able to simply proceed in a straight line. » Continue Reading.
On a morning walk around the pond, the dog and I encountered a dead shrew – perhaps the unfortunate casualty of a neighborhood feline or a red fox (shrews are well-known for being distasteful to mammalian predators). When I picked it up and noticed its velvety black fur, long tail, and unusually large hind feet, I realized that this was a species I did not recognize. I tossed it on the passenger seat of the car so I could identify it later at work.
Like all shrews, this small, mouse-like mammal lying on my desk had a long pointed snout and tiny eyes. Its minuscule ears were barely visible, covered by short velvety fur. As I stroked the soft black hair, I noticed that the fur offered little resistance no matter which direction my finger passed over it, a perfect adaptation for life underground, permitting the animal to slide easily through a tight tunnel in any direction. » Continue Reading.
Since as far back as I can remember, the sight of a group of turtles basking on a log has made me pause to enjoy their prehistoric appearance. Most summer days during my early childhood were spent wading in neighborhood ponds to stalk painted turtles and spotted turtles with a long-handled net, while avoiding the larger snapping turtles that were lurking beneath the surface. Stumbling upon an eastern box turtle or a musk turtle, something that has happened far too infrequently, was often the natural history highlight of my year.
This summer, I had what may be my best turtle day ever when I stopped my car to help a turtle cross the road. It turned out to be a rare wood turtle, the first I had ever seen, and an animal that is unmistakable for its striking appearance. » Continue Reading.
Work has began this week on a stream and habitat restoration project at Johns Brook in Keene Valley. This first phase of restoration, addressing the lower third of the impacted reach, should be complete by the end of this month and is intended to speed the stream’s return to pre-Irene character and function, reduce bank erosion and improve wildlife habitat.
In the wake of Tropical Storm Irene in August of 2011, nearly half a mile of Johns Brook was dramatically altered by local officials from its natural state – from the Route 73 bridge upstream. The work was done in the spirit of public safety to remove stream blockages and protect property. Unfortunately, flattening (removing cascades and filling in pools) and straightening the stream channel reduced its ability to dissipate the water’s energy and the faster moving water causes additional flooding and erosion problems. Furthermore, the stream’s trout habitat was drastically diminished. » Continue Reading.
All mammals that employ the use of a shelter in winter instinctively attempt to find a place completely hidden from the view of humans for their home, except for one. When the time comes in late summer or early autumn for establishing a protective enclosure for the coming season of cold, ice and snow, only the beaver places its residence in a spot that can be readily noticed by a person passing through the area.
When hiking, canoeing, biking or driving past a stretch of quiet water, you can often see a sizeable, cone-shaped mound of sticks packed with mud jutting well above the water’s surface. This is the temporary, winter residence of a family of beaver which provides these flat-tailed creatures with shelter from the cold, and protection against their few natural enemies. » Continue Reading.
The Biodiversity Research Institute’s (BRI) Adirondack Center for Loon Conservation will be holding its first-ever Loon Quilt Raffle. The hand-made quilt depicts a pair of loons raising two chicks on an Adirondack lake. The queen-sized quilt was created by Dr. Nina Schoch, Coordinator of BRI’s Adirondack Center for Loon Conservation, based on a McKenna Ryan design, and quilted by Susan Ochs of Saranac Lake.
“The proceeds from the loon quilt raffle will help support our loon research and outreach initiatives over the coming year. It was a lot of fun making this unusual quilt,” said Dr. Schoch, “and I hope the support it provides will enable us to continue to address numerous threats to Adirondack loons and the lakes and ponds where they live.” » Continue Reading.
