Lapland Longspur

The Lapland longspur breeds in the arctic and winters in the central United States, with populations into the millions overwintering on the Great Plains. Wisconsin longspurs have more modest groupings, but will flock in large groups in open areas of fields, prairies, and meadows, especially if manure has been recently spread.

Distinguished with a reddish wing patch and black patches on each cheek, the Lapland longspur's call, a bubbly chirp, can make it stand out in a drab field.

The bird has adapted to a diet of seeds, as its beak can attest. While seed collectors at Faville Grove might be lucky to collect a bucket full of seed, Lapland longspurs are masterful seed collectors, especially given their size. A single bird can eat up to 10,000 seeds per day. They prefer seeds and waste grain while overwintering in Wisconsin.

With drab plumage while it spends time in Wisconsin, the longspurs largely go unnoticed while occupying this southern “tundra.” But these are very interesting birds. Researchers have investigated the circadian rhythms of longspurs, and demonstrated that the species is regulated by an internal circadian clock that cycles endogenously (from within the organism) throughout the constant daylight of the arctic summer. The mechanisms through which the species accomplishes this rhythm are not clear, but even in the never-ending daylight of an arctic summer, male birds sing in the morning at roughly the same time.

You can find Lapland longspurs throughout the Faville Grove Sanctuary in open areas and near agricultural fields.

Goose Pond Christmas Bird Count

Goose Pond Bird Count- 20 species and 733 individuals. 

Six people participated in the Goose Pond unit of the Poynette Christmas Bird Count (CBC) held on the last day of the year.  Beginning in 2000, two to four people have spent most of the day counting birds at Goose Pond Sanctuary.  This year we were pleased to have Maia Persche, her father Todd, and Jim Otto, join Mark, Jim Hess and Bill Walters on the CBC.  Jim and Bill have participated on the count for many years.  Our 2,000-acre count area includes MAS’s 660 acres, Judi Benadi’s 80 acres, Manthe’s 66 acres, and surrounding lands.

The count highlight was Maia, Todd, and Jim Otto’s search of the seven acre food plot where Maia has been conducting weekly counts since late August with the assistance of Jim Otto. In the food plot they found a flock of 35 pheasants, 1 Cooper’s hawk, 1 rough-legged hawk, 217 mourning doves, 1 downy woodpecker, 4 black-capped chickadees, 126 American tree sparrows, 8 dark-eyed Juncos, 3 cardinals, and 24 goldfinches.  The Cooper’s hawk was seen flushing the mourning doves.  The downy woodpecker may have been feeding on insects in the sorghum stems and the other birds were likely feeding on sunflowers, sorghum seeds, or weed seeds.

Ten species were found, at the fully stocked feeders that include suet, at the Kampen Road and the Prairie Lane residences.  Totals were 4 rock pigeons, 3 mourning doves, 3 downy woodpeckers, 8 chickadees, 19 American tree sparrows, 3 dark-eyed Juncos, 1 house finch, 60 American goldfinches, and 26 house sparrows.  The doves and goldfinches move back and forth from the feeders to the food plot.

New to the Goose Pond count was a swamp sparrow that was found on the Manthe farm, bringing the total species found in the unit to 38 species.

The six of us also searched part of Judi’s property that includes shrub and tree plantings and 45 acres of restored prairie.  Highlights at her parcel included five pheasants, five blue jays, and 17 chickadees.

Other interesting species included 15 Canada geese that silently flew over, and one American kestrel, not far from the nest box on the Lapinski – Kitze Prairie. We ended with 50 pheasants, the highest number since 2009 when 126 were found.

Mark found the top bird of the count and the last bird he saw in 2016 when a short-eared owl with a moth-like flight was seen in the headlights as it flew down Kampen Road adjacent to the food plot at 5:13 p.m.   The grassland and food plot provide ideal small mammal habitat and that is why we had a red-tail hawk, rough-legged hawk, American kestrel, and the short-eared owl in those areas. 

Wild turkeys have never been seen in this count area, however they came close to being added when Sue and Diane Tomlinson saw a flock of 34 about 300 yards from our count area.  Missing from the count were snow buntings and Lapland longspurs.

The bird species and numbers help show the importance of habitat and feeders for our winter birds.

Friday "Fur" Feature: Muskrats

A Muskrat House from a Muskrat Perspective, Photography by Drew Harry

“The wonderful thing about muskrats in my book is that they cannot see very well, and are rather dim, to boot. They are extremely wary if they know I am there, and will outwait me every time. But with a modicum of skill and minimum loss of human dignity, such as it is, I can be right “there,” and the breathing fact of my presence will never penetrate their narrow skulls.” —Annie Dillard from Pilgrim at Tinker Creek

It's hard to know a mammal that's hardly seen, but then again it's hard to know most wild mammals. Birds are easier with songs and calls, less likely to disappear underwater, like a muskrat. Perhaps flight makes birds less wary of being seen, but then again a bird always seems to fly away just before one catches a marker of identification.

I've had a few chance encounters with muskrats, but they appear on the fringes and vanish underwater within seconds. I've chased them in kayaks, only for the muskrat to amble through the water, up a bank, and out of site, as if I were no more concern than a fall breeze.

In winter, muskrats take center stage. Faville Marsh's peripheral moat is covered with muskrat houses. Trapped under the ice for the winter, these muskrats become as evident as walruses atop the ice. Yet they remain unseen.

Each lodge houses on average five muskrats, and can house up to twenty. High overwintering densities of 35 muskrats per acre have been recorded. The density helps keep muskrats warm over winter, along with their rich walnut fur coat. Another method is the use of sphagnum in the construction of their houses. Here, the muskrats parallel the people of the Russian Taiga who insulate their winter hunting cabins with sphagnum.

Muskrats follow the ecological rule of bigger litter sizes in higher latitudes. Wisconsin muskrats average two litters of 14-15 offspring per year and will mate from early spring until fall. Remarkably, it is estimated that 87% of a population will die in the first year, with only 2% surviving past year two.

Muskrats cycle in 10-14 year periods, and it seems that they respond to water level fluctuations. Drought and disease can decimate populations, whereas high water years can see exploding populations. It's difficult to know for sure, but perhaps the wetter than normal fall this year bolstered the population of muskrats at Faville Grove.

I've noted a few sets of tracks leading out from muskrat houses, often considerable distances. Typically muskrats will wait under the ice all winter, ranging a mere five meters from their house, feeding on stored cattails and bulrushes in their lodge and pondweed and arrowhead beneath the ice. It's possible that these muskrat wanderers were booted from the house and forced to find shelter elsewhere. These exiled muskrats will often make shelter in the dens of other mammals.

Muskrats need water in winter to feed and drink. A cover of ice is desirable for cover from predators and for insulation. The ice also can come crashing down on a population. If the ice freezes through, the muskrats will wander elsewhere, vagabonds for the mink, coyotes, bobcat, foxes, and owls. Faville Marsh presents an interesting study because the water depth is no more than three feet, and one would presume this moat would freeze through. However, within Faville Marsh's complex of tamarack are groundwater seepages. This relatively warm groundwater does not freeze, and may provide aquatic habitat for muskrats.

Breeding Bird Point Count Project at Goose Pond Sanctuary

Goose Pond Sanctuary - 2016 - 51 Breeding Species and 1,663 Breeding Pairs

At the end of the year, the media reflects on the past year's highlights.  Looking back at Goose Pond Sanctuary, the highlight for 2016 was the breeding bird point count project that Heather Inzalaco, UW-Madison Environmental Studies, conducted for her master’s project. Heather can identify over 200 species by call and did outstanding work on this project. Our goal for many years was to learn the species and numbers of birds breeding at Goose Pond Sanctuary.

Heather conducted two rounds of point counts at our 660 acre sanctuary (1,542 pairs) and at the Manthe’s 65 acre farm (121 pairs) located east of Goose Pond Road and north of the “east” pond, and now restored to prairie.  She also surveyed Erstad Prairie and Otsego Marsh. Heather developed the point count protocol that included 10 minute stops 77 yards apart, in all habitats except for open water. We added data from our waterfowl pair counts and other observations including birds around the residences. Heather also prepared detailed maps for all parcels. Males were counted as pairs. If Heather observed 3 pairs and 2 singing males it was counted as five pairs. The highest number from the first or second counts was counted for each survey block. Species like the sedge wren, dickcissel, and American goldfinch had higher numbers on the second count. This summer’s survey provides a baseline for future breeding bird surveys.

Heather also recorded species that she confirmed nesting (nest with eggs, feeding young, or fledged young are in bold) and we also added confirmations from atlas work in 2015 and 2016. If a nest was found photos were taken to document the nest for the Breeding Bird Atlas II project. Species of Greatest Conservation Need (SGCN) are designated by the Department of Natural Resources.

51 Species and 1,633 Pairs –

Geese and ducks included Canada geese 1 pair, mallard 93, blue-winged teal 7, northern shoveler 3, green-winged teal 4, hooded merganser 1, and ruddy duck 1.  Female mallards usually return to where they were hatched and with very successful nesting many females are returning. A brood of hooded mergansers jumped from a nest box at Sue Ames Prairie.

Wetland birds included sandhill crane 2, marsh wren 7, yellow warbler 14, and swamp sparrow 15. The nesting pair of cranes on the west pond raised one young.

Shrub, fence row, savanna and woodland species included wild turkey 6, mourning dove 8, northern flicker 1, alder flycatcher 7, willow flycatcher (SGCN) 15, eastern kingbird 6, warbling vireo 3, American robin 39, gray catbird 16, brown thrasher (SGCN) 11, field sparrow (SGCN) 1, northern cardinal 5, indigo bunting 3, orchard oriole 1, and Baltimore oriole 2. There may have been more than 8 pairs of mourning doves since Sara Kehrli, Columbia County Wildlife Biologist, banded 88 doves at Goose Pond this summer.

Species found mainly around the residences, in nest boxes, and in miscellaneous habitats included killdeer 10, rock pigeon 2, American kestrel 6, eastern phoebe 1, tree swallow 64, barn swallow 40, house wren 11, eastern bluebird 2, European starling 2, chipping sparrow 3, common grackle 8, house finch 1, and house sparrow 8. The 40 pair of barn swallows nested in our barn at the Kampen Road residence.

Over 460 acres of restored prairie were surveyed and this large acreage accounts for the bulk of the birds. Grassland birds found included ring-necked pheasant 28, northern harrier (SGNC) 2, sedge wrens 62, common yellowthroat 212, clay-colored sparrow 128, savanna sparrow 1, song sparrow 302, dickcissel (SCGN) 23, red-winged blackbird 365, eastern meadowlark (SCGN) 46, brown-headed cowbird 17, and American goldfinch 47. This is the first time that two harrier pairs nested at Goose Pond and both fledged young. All the dickcissels were found at the 80-acre Ankenbrandt Prairie. One of our favorite birds that are increasing in numbers is the eastern meadowlark, and we enjoy hearing its call.

Almost 50 years have passed since Madison Audubon acquired the first parcel at Goose Pond, a gift to our feathered friends that keeps on giving. The birds thank all of our members, donors, volunteers, and interns who have been involved with land acquisition and habitat restoration at Goose Pond. Thanks to Heather for all her research work.

Bald Eagle

Bald Eagle, Photography by Ben Bawden

A national emblem, a conservation success story, and scorned by Ben Franklin, the bald eagle resonates throughout the popular conscience of the United States. A bird of many misconceptions (especially noted by Ben Franklin) the bald eagle is not a voracious predator. Rather, the bird voraciously scavenges, even stealing fish from osprey and otters. In southern Wisconsin, a popular winter meal for bald eagles is fish carcasses from ice fishermen and deer carcasses.

Imagine the bird's fierce call echoing through the pineries of northern Wisconsin. Here, another misconception...the call of the bald eagle more resembles that of a gull. The characteristic screeching heard in Hollywood belongs to the red-tailed hawk.

Look at the eagle's bald head as it reaches for skyward, catching an updraft. Well, you probably know that the eagle isn't actually bald.

In Wisconsin, bald eagles nest throughout the state, in 69 of 72 counties based on Wisconsin Department of Natural Resources aerial surveys in 2015. The state hit a low number of recorded occupied nests in 1974 at 107, mostly nesting in north central and northwestern Wisconsin. Low numbers were a result of habitat destruction, shooting, and toxic chemicals like DDT. In 1972 the bird was placed on the Wisconsin Endangered Species List, and in 1978 the bird received federal protection as an endangered species in most states, though it received threatened status in Wisconsin. Since then, the population has soared. By 1994, over 500 nests were found throughout the state. By 2005, over 1,000 nests. 2015 saw an estimated 1,465 nests throughout the state, as the bird has expanded its range farther into southeastern Wisconsin.

In 1963 there were an estimated 487 nesting pairs in all of the United States. In 2015, 497 pairs of bald eagles nested in zone 2 of WDNR surveys, an area that includes all or parts of ten counties in north central Wisconsin, thought to be the highest concentration of bald eagles in the world. Not coincidentally, this area is also home to some of the highest densities of lakes in the world.

Open water beckons bald eagles because of abundant prey opportunities. Throughout winter, you can see bald eagles congregating along open water of the Wisconsin and Mississippi rivers. Enjoy Eagle Watching Days in the Sauk City area January 13th and 14th.

Here at Faville Grove Sanctuary, we are lucky to have an occupied bald eagle nest this winter. Located about two thirds of the way up a big cottonwood, near the base of the tree, the large nest stands out against the treeline. Follow Prairie Lane down to where it turns north, and look east towards the Crawfish River and you will see the big nest, probably 5-6 feet in diameter and over two feet tall. Please view the nest from Prairie Lane, as it is located on private property.

The eagles occupying this nest could begin laying eggs as early as mid-February, and we are excited to follow their progress!
