It's time again for the annual Christmas Bird Count (CBC).  Not that it actually occurs on Christmas Day anymore, but now it can be any day from December 14 through January 5 (i.e., 11 days before and after Christmas).  The CBC was invented in 1900 as an alternative to the Christmas side hunt in which teams of men went out and shot everything in sight.  The biggest pile of feathered and furred animals won.  More of the history can be found on the Audubon website.  You also can follow links to individual counts and past results.

The Christmas Bird Count is an annual citizen-science project now in its 112th year.  Such a long-term perspective allows ornithologists to monitor population trends - some good, some bad.  Please consider joining one of the five local counts inside the Adirondack Blue Line [note: the Ferrisburg, VT CBC circle extends west across Lake Champlain into the Adirondacks], or one of the many peripheral counts in New York if you can make it.  If you lack confidence, it's often possible to be paired with an experienced observer.

Counts inside the Blue Line:

Bolton Landing - code NYBL

Elizabethtown - code NYEZ (Sun., Dec. 18)
[Ferrisburg, VT - code VTFE (Sat., Dec. 17)]

Old Forge - code NYOF

Saranac Lake - code NYSL (Sun., Jan. 1)

Closest peripheral counts:

Fort Plain (Fri., Dec. 30)
Massena-Cornwall - code NYMC (Tue., Dec. 27)

Plattsburgh - code NYPL (Sun., Dec. 18)

Saratoga Spa - code NYSS

Thousand Islands - code ONTI

Watertown - code NYWA

Wilson-Lake Plains - code NYWL

Counts are conducted in predetermined 15-mile diameter circles during a 24-hour period (midnight to midnight).  In fact you can start at midnight by listening for owls! (but most people wait till at least dawn).  For easier coverage, the circles are divided into sectors (sections) and participants can bird as long (or short) as desired, but time and any mileage must be recorded.  To cover administrative costs and keep the count going there is a $5 participation fee for anyone over 18.

If you live within the 15-mile diameter circle of a particular count, you also can choose to stay home and just watch your feeders and count all the yard-birds including any fly-overs.  All species count.  Keep track of the maximum number of individual birds of each species seen and the length of time you spend watching for birds.  Contact the compiler in advance so he/she knows to expect your data; final results can be phoned in the evening.

(Most) counts are followed by a compilation dinner or meeting.  For example, the E-town post-count meeting will be at the Deers Head Inn Restaurant (7552 Court Street) in Elizabethtown, NY around 5:00 pm.  Contact Charlotte Demers in advance.  For the Massena-Cornwall CBC, contact Eileen Wheeler.  For Fort Plain, it's Tom Salo.  For Saranac Lake, Larry Master.

Crossbills

Crossbills -- © Dave Spier

           White-winged Crossbills, an irruptive species in winter, are frequently reported on NNY Birds.  Their traditional diet of Canadian spruce seeds sometimes runs low and once exhausted, the birds head south in higher numbers.  The birds' small, thin bills, which are crossed at the tips, allow them to specialize on the small, soft cones of Spruces (White, Black, and Red), larch, Eastern Hemlock, Northern White Cedar and Red Cedar.  The White Pine, unlike other eastern pines, has soft cones that can be utilized by crossbills.  They also use Douglas Fir and Blue Spruce, introduced species in the east.

          White-winged Crossbills (Loxia leucoptera) are medium-sized finches with a year-round range from Alaska eastward through the boreal forest zone to the Canadian Maritimes.  There’s a fair number of breeding reports from around the Adirondacks with a concentration of confirmed sightings in northern Herkimer County and adjacent Hamilton County.

           In the winter, they migrate erratically into the northern states with sporadic reports from the central states.  Adult males are dull red with black wings and two prominent white wingbars.  Females are yellowish gray with similar wings.  Juveniles are heavily streaked and somewhat resemble Pine Siskins, another winter visitor.   In Europe the white-winged is called the Two-barred Crossbill.

            Another species, the Red Crossbill (Loxia curvirostra) is similar, but has a heavier bill and lacks the white wing bars.  [In rare cases, a variant of the first-year male can display weak wingbars.]  There are nine recognized "types" (similar to subspecies) of Red Crossbills and some of these may be evolving into separate species.  The specially adapted beaks are pointed and crossed at the tips, but the size and exact structure varies among the different types depending on the species of cone they are best adapted to.  The heavier bill allows Red Crossbills to pry out seeds from heavy pine cones in addition to spruce and fir.  An individual crossbill can extract and eat 3000 conifer seeds in one day, which probably explains why they keep moving in search of new food sources.

Pine Siskins

Siskins -- © Dave Spier

           

Pine Siskins (Spinus pinus) are heavily streaked with yellow feather edges on the wings and yellow patches on the inner tail sides.  The amount of yellow varies with less on young birds and more on adult males.  Since this gregarious bird tends to travel in flocks, at least some members will show varying amounts of yellow.  There are also two buffy wing bars.  Siskins also hang with goldfinches; both are members of the same family and about the same size and once shared the same genus (Carduelis).  Female House Finches are similar, but larger with lower-contrast streaking.  Siskins also resemble redpolls, another finch, but redpolls have a red cap.  Siskins have notched tail ends, but so do female Purple Finches which have high-contrast streaking, a plumper build and heavier bills.  If you’re having trouble, the best bet is to take a photo and send it to northeastnaturalist@yahoo.com

When winter food supplies are short in their Canadian boreal homeland, siskins wander south, showing up first in similar forested habitats in the Adirondacks where significant flocks have been reported throughout October and November.  (Details can be found on the Google group, Northern New York Birds.  There's also a link in the right sidebar.)  Recent reports [Nov. 29] have come from Joan Collins at Sabattis Bog, Little Tupper Lake, several locations on Rt. 28N including flocks totalling 200 in Minerva, and the Roosevelt Truck Trail with 150 siskins.  Joan's more recent posts [Dec. 4] from Horseshoe Lake and Low's Ridge-Upper Dam Trail have reported smaller numbers in these locations.

Pine Siskins are one of several kinds of birds referred to as “irruptive species,” meaning they can show up unexpectedly anywhere in the lower 48, and the pattern changes from year to year.  A few birds may linger into the spring and act as though they will nest locally, which they do in New York State.  The heaviest concentration of nesting records occurs in three clumps from roughly Norwich to Saranac Lake and Lake Placid.

Siskins are seed eaters.  They prefer conifers [spruce, pine, cedar and hemlock], but also eat seeds from deciduous trees [especially birch], shrubs [particularly alder], flowers [weeds] and grasses.  They readily come to thistle-seed feeders, sometimes in large flocks, but also eat sunflower seeds – basically the same diet as goldfinches.  By the way, goldfinches and siskins can feed upside down.  Special feeders are made with the seed holes below the perches.  In the case of siskins the skill is useful in extracting seeds from conifer cones.

Silver Lake Bog -- © Dave Spier

I know it simply as Silver Lake Bog, but in the 2011 annual report from The Nature Conservancy’s Adirondack Chapter, it’s listed as Silver Lake Bog Nature Preserve and on eBird it’s “Silver Lake Camp Preserve” referring to the Silver Lake Camp for Girls which operated from 1911 to 1972 before 61 acres were donated to the recently-created Adirondack Nature Conservancy in the mid-70’s to become one of its earliest preserves.  The original size has grown to 98 acres now.  You can take a virtual tour via a slide show on the TNC website.

The bog is in the southwestern corner of Clinton County on the old Hawkeye Road off Union Falls Road.  From Hawkeye travel west about 1.5 miles and turn south on Old Hawkeye Road.  Parking is about a half mile down the dirt road.  Exact directions [with an interactive Google map] are on the Conservancy’s website.  In DeLorme's N.Y. Gazetteer, Silver Lake's north shore is bottom center on page 102, but the Old Hawkeye Road is too short to be labeled.

The highlight of the preserve is a roughly half-mile boardwalk west across the wetlands.  The depression supports a Northern White Cedar swamp and Black Spruce-Tamarack bog.  A trail guide describes plants and animals at 15 stops along the Bog Walk.

At the far end of the bog walk, the trail rises into an upland forest of northern hardwoods and hemlock and then turns south on its way to a pine bluff overlooking Silver Lake.  The flip side of the trail guide describes eight stops along this Bluff Trail.

The preserve seems larger than its size because it’s generally narrow and L-shaped.  Total trail length is 1.25 miles one way to the lake.

Birds at Silver Lake Bog

The eBird bar chart for Silver Lake Camp Preserve lists 70 species so far, but the data is very incomplete, especially during the winter months.  (There’s no data for November and January and none for the first three weeks of December.  For all of February there is only one week covered and that has only 2 bird species.)  If you’re in that area, please stop and record any and all birds seen or heard, even if they’re just from the beginning of the trail near the road, and submit to eBird.  At least it will be a start toward filling in the gaps.  Another hole in the data is the lake itself; there are no eBird records for waterfowl – zero – not counting Common Loon reported in May and July at this location.

For another perspective on the bird life in the general vicinity, Silver Lake Bog is in N.Y.S. Breeding Bird Atlas block 5892A.  A block is roughly nine square miles and this one includes the western 3/4ths of Silver Lake, the eastern part of Union Falls Pond and the west end of Taylor Pond.  There were 88 species (including Wood Duck, Mallard and Common Merganser) reported in 2000-2005 during the nesting seasons.  Of the Anatidae waterfowl, only Mallard is actually a confirmed breeder in 5892A.  There were 30 other species also confirmed.  [To see the complete list, click the link above, type in 5892A and click "submit."]

Boreal Chickadees -- © Dave Spier

Boreal Chickadee in a White Pine by Dave Spier [scanned from a old slide]
see the links at the end of this blog post for great photos by other photographers

Judging by recent reports on Northern New York Birds, there's no shortage of Boreal Chickadees (Poecile hudsonica) in the Adirondacks.  If you're looking for a specific location, try the Roosevelt Truck Trail off Route 28N in Minerva.  The trail runs north from the old, narrow sideroad 1.6 miles north of the Boreas River bridge; details are in the ADK guidebook.  Birding guide, Joan Collins, said, "I had a beautiful walk on the Roosevelt Truck Trail [November 16]. I don't recall ever finding as many Boreal Chickadees on one walk. Views of the Boreal Chickadees were terrific throughout the hike.”

They're also likely to be encountered in northern New England, much of Alaska and certainly in their trans-Canada strongholds from coast to coast south of the tree line.  For an eBird range map, look under View and Explore Data, and then zoom in for finer detail.  At the highest resolutions you’ll find individual locations and checklists.  If you continue north on the map through Canada, you’ll find the data is incomplete, so if you’re ever up that way, please submit your complete checklists to eBird and help fill in the gaps.

Not surprisingly, almost all of the 2000-2005 Breeding Bird Atlas records for Boreal Chickadees are clustered in the Adirondacks.  The two exceptions are on the Tug Hill between Lake Ontario and the Adirondacks.

The Boreal's preferred habit is dense northern (boreal) coniferous forests, so whenever they move in search of winter food, they're usually found in a similar environment, often in association with their close relatives, the Black-capped Chickadees (Poecile atricapilla).  At a distance the two species can be separated by song, with the Boreal's being a slower, raspier version of the familiar "chicka-dee-dee-dee," but more like "che-day-day" at a lower pitch.

All chickadees come to suet and sunflower seed feeders.  If you have conifers (spruce, pine, firs or hemlock) in your yard or nearby, pay some extra attention to any chickadees coming to your feeder.  Watch for any with a brown cap, gray sides of the neck behind the white face, and light-brown flanks.  (All chickadees have the black bib and underthroat.)  If you see one [or more], please report it [them] to eBird, or email me at northeastnaturalist@yahoo.com

MOOSE -- © Dave Spier

Female Moose (October)  -- © Dave Spier

In an issue of D.E.C. Field Notes (Nov. 4), there are links to a Moose fact sheet and a gallery of NY Moose photos from various counties (mostly Hamilton and Essex, plus Warren, Herkimer, St. Lawrence, Oneida, Lewis, Rensselaer, and Saratoga). A video about tagging and tracking Moose in NY was not working.  North Country Public Radio featured moose as a Photo of the Day.

I have no secret hotspots for finding Moose in the Adirondacks. The last estimates I saw of Moose numbers in New York ranged up to 800, based on statistical analysis of sightings, vehicle collisions and reports from hunters. (Moose are protected in New York, so these were people hunting deer, bear, ducks, etc.) Average that population across the region and you get 7500 acres per Moose. Ideal habitat is a mix of forests with both deciduous and coniferous trees for shelter and browse, plus small clearcuts for regeneration of additional browse plus wetlands for aquatic vegetation eaten in the summer. Moose are therefore unevenly spread across the Adirondacks and some of the population is located in the Taconic Highlands.

Autumn Gold -- © Dave Spier

Mention the word "conifer" and it's likely the concept of "evergreen" comes to mind. Most groups of conifers keep their needles through the winter. One big exception is the larch, or tamarack, the only common deciduous conifer. It turns gold in the fall (roughly the third week of October) and then drops its needles. During the winter, when the twigs are bare, take a closer look at the knobby texture of the year-old twigs.

Larch needles grow in dense, radial clusters supported by short, woody knobs on the sides of last year's twigs. One cluster can have 30 needles growing in a circular whorl. On this year's twigs, the soft needles grow singly.

Larches begin flowering at 15 years of age. The male flowers are tight clusters of stamens, while the female flowers are larger, scaly rosettes. Like other members of the Pine family (Pinaceae), they are wind pollinated. The female "larch roses" develop into barrel-shaped cones with overlapping scales and hollow tips. Immature seed cones are bright red. They grow upright on the ridged twigs, reach a length of a half inch or slightly more, then turn brown as they mature and may persist for several years. Inside the cone scales are brown seeds with firmly-attached, membranous (papery) wings affixed at one end.

Larches are related directly to pines and less directly to spruce, hemlock and Balsam Fir. All of these conifers produce so-called naked seeds. The Greek word for naked is gymnos, and yes, it's the original root of the word gymnasium. Combine this with sperma, the Greek word for seed or germ, and you get the botanical classification gymnosperm. (Other members of this group include yews, redwoods, cycads, cedars, cypress and the Ginkgo.) By contrast, angiosperms, or flowering plants, are evolutionarily more modern. Their seeds are enclosed by the ovary.

The native Eastern [American] Larch (Larix laricina) grows in bogs and boreal (northern coniferous) forests wherever it can get enough sunlight. It is one of the pioneer tree species but cannot grow in the shade of other trees. Overall, larch is now more abundant than it was before the logging of the late 1800's and early 1900's opened the forest canopy and allowed more light to reach the ground. (The Boreal Life Trail at Paul Smiths is a good place to see larches in their natural habitat.) Altitude is little hindrance to larches; they grow at 4620' on Haystack. At lower elevations, larches can reach heights of 60 to 80 feet, but still die out as mature forests reclaim the land and close the canopy, thereby preventing rejuvenation from seedlings.

European Larch (Larix decidua) is widely planted as an ornamental and for timber harvesting. Pure stands of tall larches are very likely this species.

Fortunately, larches are still commonly called Tamaracks (Algonquian). "Larch Lodge" just doesn't have the ring of "Tamarack Lodge."
