Adirondack Birds: Soulful Music of the Hermit Thrush

Hermit ThrushIn the weeks surrounding the emergence of leaves on the shrubs and trees in the Adirondacks a rich variety of sounds, unlike that which is heard during any other time of the year, occurs in our forests. Some participants in this natural symphony bellow out a perky series of melodious notes, like the winter wren and red-eyed vireo, while others such as the robin and white-throated sparrow have a more stately quality to their voice.

A few, like the ovenbird and chestnut-sided warbler, contribute an intense and serious refrain to the mix, and then there is the soulful music of the hermit thrush, which frequently opts to perform solo after most of the other voices have subsided for the evening. » Continue Reading.

Ruffed Grouse: Breaking The Sound Barrier

grouseA distant motor thud-thud-thuds as if trying to start, then dies away.  The noise repeats, and again dies off. I’ve been fooled by this sound, wondering who could be trying to start a 2-cylinder engine in the middle of the woods. This mechanical noise, of course, is really the drumming of a male ruffed grouse.

People once thought that male grouse struck their wings on a hollow log to produce this low whumping, but better observation revealed something far more astonishing. The bird stands bolt upright on a log, leans back on his tail, and fans his wings vigorously – so fast, in fact, that the wings achieve the same speed as the sound waves generated by their passage through the air. This causes the sound waves to “pile up” into a penetrating shock wave, also known as a sonic boom. For a one-and-a-quarter-pound grouse to exert such force takes strength and perseverance. Novice males have been observed going through all the motions and not producing any sound at all. » Continue Reading.

DEC Plans To Introduce Spruce Grouse

close-up-of-maleThe state may introduce spruce grouse into the Adirondacks as early as this year to bolster a native population that appears headed for extinction.

Without intervention, the state’s spruce-grouse population could vanish by 2020, according to a recovery plan released today by the state Department of Environmental Conservation.

“The spruce grouse is perhaps the best-known icon and a perfect representative of boreal habitats in New York,” said Michale Glennon, a scientist with the Wildlife Conservation Society’s Adirondack Program, in a DEC news release. » Continue Reading.

Outside Story: The Ecology Of Leaf Litter

It’s one of the pleasures of fall: walking in the woods on a warm day, scuffing my feet through a deep layer of newly fallen leaves. Looking down, I notice the gold coins of aspen leaves against the bread-knife serrations of brown beech leaves. My feet make that “swoosh, swoosh” sound that takes me back to when I was a kid.

It’s November and the color blast has faded. The woods are gray and brown. The much admired “fall foliage” has drifted earthward to become the more prosaic “leaf litter.” I understand the term, but the word litter grates a little. It connotes trash, yet leaves are just the opposite of trash. Their contribution to forest health, to the ecosystem, is incalculable. They help make the forest what it is.

The Attack of the Ruffed Grouse

Ruffed GrouseIt is traditional backwoods wisdom to avoid getting between a mother and her babies, and while this advice usually pertains to the black bear, it could also apply to several other forms of wildlife that reside in the Adirondacks.

In late spring many infants are emerging from the safety of their den or nest and most mothers try to provide some form of protection from potential danger to their babies. Perhaps the most remarkable display of parental courage for a creature of its size is seen in the hen ruffed grouse. This bird will aggressively confront and challenge any human that happens to come too close to its recently hatched chicks. » Continue Reading.

Spring Turkey Season Opens Today

The 2012 spring turkey season opens today (May 1) in all of upstate New York lying north of the Bronx-Westchester County boundary. An analysis of the 2011 spring turkey take, including a county-by-county breakdown, can be found on the DEC website. Take figures for the 2011 fall turkey season and county-by-county breakdown can also be found online.

DEC is looking for turkey hunters to participate in their ruffed grouse drumming survey as hunters are ideally suited for monitoring ruffed grouse during the breeding season. Turkey hunters can record the number of grouse they hear drumming while afield to help DEC track the distribution and abundance of this game bird. To get a survey form, go online or call (518) 402-8886. To participate in DEC’s Summer Wild Turkey Sighting Survey or other wildlife surveys visit the “Citizen Science” page of the DEC website. » Continue Reading.

Adirondack Wildlife: The Wood Duck

Strong and frequent southerly breezes, a disappearing snow pack at low elevations and the presence of large stretches of open water along streams, in the backwater of rivers and in marshes prompt the return of numerous forms of waterfowl to the Adirondacks.

Even though mid March is early for the arrival of some migrants from their wintering grounds, when the opportunity arises to reconnect with the area used for breeding, these flat-billed, webbed-footed birds take advantage of the favorable conditions and fly north. Included with these returning birds is one of the most colorful and handsome species of waterfowl in North America – the wood duck. » Continue Reading.

Adirondack Wildlife: The Saw-Whet Owl

As the moon becomes full this week, the opportunity arises to be able to hike on a woodland trail or backcountry road well after dusk without the aid of an artificial light. Regardless of the amount of cloud cover, there inevitably exists on nights around this phase of the moon enough natural light to be able to travel into the woods using only lunar illumination. While nocturnal outings in mid spring can provide a great audio experience, there are relatively few sounds that disturb the silence at this time of year. However, among the seldom noted noises that occur in the Adirondacks in March and April is the call of the Adirondacks smallest nighttime aerial predator, the saw-whet owl.

When initially heard, few people associate this distinct sound with that of an owl. Rather than bellow out muffled hooting notes, the saw-whet makes a rapid series of short “beeps” that resemble the noise produced by a back-hoe or other piece of heavy equipment when in reverse. The very quick tempo, or rate at which the saw-whet makes these beeps, (over a dozen in a 10 second interval of time) creates an air of haste to this bird’s call. Also, once it starts calling a few hours after sunset, the saw-whet continues uninterrupted for several hours in its seemingly intense bouts of vocalization. » Continue Reading.

Wally Elton: The Great Backyard Bird Count

For those who enjoy birds, Presidents’ Day weekend brings a chance to combine the pleasure of birdwatching with contributing to science’s understanding of current bird populations and their conservation. The 15th annual Great Backyard Bird Count (GBBC), organized by Audubon and the Cornell Lab of Ornithology (and Bird Studies Canada north of the border), is a nationwide mid-winter bird census that calls on bird enthusiasts everywhere to help assemble a picture of bird numbers and distribution. This year’s count dates are this week, February 17 – 20.

The Disappearing Adirondack Spruce Grouse

The spattering of sizable tracts of boreal forests that remain in the Adirondacks serve as home to several species of birds that have evolved the ability to survive in northern taiga woodlands. Among the feathered creatures that are well adapted for a life in lowland stands of conifers is the spruce grouse (Falcipennis canadensis), a dark colored bird viewed by some as being as much a symbol of the Great Northwood’s as the moose.

As its name implies, the spruce grouse inhabits those softwood forests dominated mainly by spruce; yet not all spruce forests serve as home to this northern bird. High elevation forests that cover the upper slopes of our tallest peaks are not as suitable as lowland locations despite the similar presence of spruce and balsam fir. Because higher altitudes are more frequently buffeted by strong winds, the microclimate that exists there is more adverse than the one that characterizes sheltered, lowland settings. » Continue Reading.
