Survey Finds Birds Are Moving Uphill On Whiteface Mountain

American Robin by Wikimedia user MdfA survey of birds on Whiteface Mountain has found that many species have moved uphill in the past forty years, possibly in response to climate change.

New York State Museum curator Jeremy Kirchman and Alison Van Keuren, a volunteer, conducted bird surveys on the 4,867-foot peak in 2013 and 2014. Their work replicated surveys by two University at Albany biologists, K.P. Able and B.R. Noon, in 1973 and 1974. » Continue Reading.

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.

Alder and Willow Flycatchers: Sibling Species

TOS_FlycatcherBy mid-May each year I begin to look forward to the return of the alder flycatchers that nest in the willows along the stream near our house. Usually the last migrant to arrive on our property, this small, drab, gray bird with its sneeze-like song, signifies that summer is indeed just around the corner. But last year, for the first time in 20 years, another bird joined the neighborhood.

A willow flycatcher announced his presence, just a few days after I first heard the alder flycatcher. To my surprise, the two sibling species co-existed all summer, presumably both nesting in the same acre or so of shrubby wetland habitat. » Continue Reading.

The Lessons Of Awkward Adolescent Eagles

TOS_EaglesA deer died by the river near my home. The crows found it, as did other scavengers – a bald eagle, and two big brown raptors that were hard to identify. Both had white flecking on their heads, wings and bodies, but the markings didn’t match up, bird to bird. They looked unkempt and more than a little disreputable.

It turns out these were also bald eagles, but young birds, dressed in dark plumage. In common with some other long-lived species, eagles have an extended adolescence. They require about four to five years to mature. During this period they don’t find mates, establish territories, or conform to the adult dress code. » Continue Reading.

DEC Closes Rock-Climbing Cliffs For Falcons

Nesting falcons. Photo from DEC website.You know winter is coming to an end when the state Department of Environmental Conservation closes rock-climbing cliffs where peregrine falcons are known to breed.

Peregrines are on the state’s endangered-species list, and so each spring DEC closes cliffs to protect their nesting sites. Cliffs will be reopened if no nesting occurs on them. Those cliffs used for nesting will be reopened in the summer after the chicks fledge. » Continue Reading.

Great Backyard Bird Count Sets Species Record

Northern Flicker by Linda Izer in ArkansasParticipants from more than 100 countries submitted a record 147, 265,000 bird checklists for the annual Great Backyard Bird Count in February and broke the previous count record for the number of species identified. The 5,090 species reported represents nearly half the possible bird species in the world.

The four-day count marked the 18th year for the event which is a joint project of the Cornell Lab of Ornithology and the National Audubon Society with partner Bird Studies Canada. » Continue Reading.

Comments On Bald Eagle ‘Conservation Plan’ Sought

2010-bald-eagle-kodiakThe NYS Department of Environmental Conservation (DEC) “Conservation Plan for Bald Eagles in New York State” is available for public review and comment. The document provides guidelines for the future management of America’s national bird (and national animal) in the State, where it prefers to live in mature forests near large bodies of water.

Bald eagles were once common in America, but their numbers began a dramatic decline as a result of hunting, logging, habitat loss, and pollution. The publication of Silent Spring by Rachel Carson in 1962, and the modern environmental movement it helped launch, led to a new public awareness of the threats to wildlife from over-development and chemical poisoning. Eventually, that awareness and activism helped save bald eagles from extinction. » Continue Reading.

Sneaky Ducks and Scrambled Eggs

TOS_WoodDuckBabiesIf you peek into a wood duck nesting box during the breeding cycle, you might find 10 to 11 eggs, which is the bird’s normal clutch size. But you might also stumble upon a box overflowing with as many as 30 eggs. How, you might ask, can one duck lay and care for so many eggs? The answer is: she can’t.

These huge piles of eggs result from intraspecific brood parasitism, otherwise known as egg dumping. This is when a bird lays eggs in a nest that does not belong to her. Waterfowl – and wood ducks in particular – often engage in this behavior. » Continue Reading.

How Wildlife Are Affected By Intense Cold

February 15 2015 Extreme ColdIntense cold is hard on all forms of wildlife, however, some of nature’s creatures are better adapted to deal with this type of adversity than others. Those animals whose geographic range extends well northward into Canada and Alaska have evolved various strategies to cope with prolonged bouts of sub-arctic weather and are quite capable of surviving the unrelenting cold that the Adirondacks has experienced this winter.

Conversely, some components of the Park’s fauna are on the northern fringe of their range and are better suited for functioning in a temperate region, such as southern New York and the mid-Atlantic States. These creatures are probably not faring well this season. » Continue Reading.

Great Backyard Bird Count This Weekend

Snowy Owl in VermontThe annual Great Backyard Bird Count (GBBC) is a chance to be part of an international team of citizen scientists using specific scientific protocols and the power of the internet to provide data to professional environment and wildlife researchers and the scientific and educational institutions they represent.

From February 13–16, people of all ages, whether beginners or experts, are invited to support bird conservation by counting the number of birds, separated by species, seen during any outing or observational sitting. The information gathered will help researchers track changes in bird populations on a massive scale. » Continue Reading.

Adirondack Birds: The Black-Backed Woodpecker

Picoides_arcticus_-Brunswick,_Vermont,_USA_-male-8Wilderness forests serve as havens to many species of wildlife, especially those attracted to stands of old, dying and dead trees. While some people view areas of rotting timber as a breeding ground for tree disease and destructive, wood-boring insects, as well as a source of fuel for fire during periods of exceptionally dry weather, other individuals note that such sites create favorable conditions for many unique forms of life.

Among those creatures attracted to places cluttered with recently fallen logs, where frequent stands of damaged, dying and partially rotted timber jut through a broken canopy, is the black-backed woodpecker. This hardy bird is a year-round resident of the Park, inhabiting areas where old, sick, weakened and dead trees, especially conifers, abound. » Continue Reading.

Dave Gibson: Christmas Bird Counting

Phyllis Burchett - Audubon Photo AwardsPreparing for the annual Christmas Bird Count is, like the entire holiday season, on the hectic side. The binoculars and spotting scopes have been set aside and need to be found. Packing a good lunch a few hours in advance is a good idea, but rarely accomplished.

My highest hurdle is getting up and out early in the morning to meet my team of counters, whose punctuality and other habits, after nearly thirty years of counting in the dead of winter, are rather well known. » Continue Reading.

Wildlife Animosity: Crows and Owls

crowsAnimosity is an emotion not solely restricted to humans, as several forms of wildlife occasionally display an outward aversion to specific creatures, even through such an antagonistic attitude seems to have little to no value to their current survival.

Perhaps the best example of such an overt repulsion of one animal for another is the crow’s reaction to seeing an owl at this time of year. Upon detecting one of these round-faced predators, a crow quickly starts producing a squawking caw designed to summon any other crows in the immediate area. It is believed by some naturalists that a crow, upon hearing this alarm sound, will relay the information to others unable to hear the initial call that an owl has been spotted. This is an attempt to assemble as sizeable a mob of birds as possible. » Continue Reading.

Spruce Grouse: Help For A Rare Bird

Adult GrouseOnce abundant in the Adirondacks, the spruce grouse has struggled for much of the past century, but now scientists are trying to bolster the dwindling population by importing birds from out of state.

The state Department of Environmental Conservation released three spruce grouse last year and thirty this year, according to Angelena Ross, a biologist with the department.

The three birds released last year were adult females from Ontario. Only one survived the winter, and it was killed by a hawk in the spring.

In August, DEC released twelve adults and eighteen juveniles captured in Maine at three sites in the Adirondacks— two on private land, one in the Forest Preserve— near Tupper Lake and Paul Smiths. » Continue Reading.
