Goose Pond Sanctuary Butterfly Count 2020

The Mud Lake North American Butterfly Count, coordinated for over 30 years by Karl and Dorothy Legler is in the record books.  

This was the seventh year that Madison Audubon volunteers  counted at Goose Pond Sanctuary and Erstad Prairie as part of the Mud Lake Count.

Hopefully, this will be the first and last count conducted in a pandemic. We would never have guessed in a million years that a world wide virus would occur and we would be social distancing and wearing masks during the count. NOTE: We are not showing any photos of butterfly masked-bandits with their masks on.

This year we set a record with 23 participants (16 high in the past), in the number of 20 species (19) and a high of 56 northern crescents (53). Participants ranged in age from 8 to 70 years old. We were glad to have the Hasburgh family on the count and were pleased to learn that sons Fletcher and Ranger studied up on their butterflies the day before. Fourteen of the participants were in their 20s and 30s. 

Two new species were added to the list, the silver-spotted skipper and the banded hairstreak. The silver-spotted skipper has been seen before at Goose Pond but not on the official count.

Graham photographed the hairstreak and identified it from the Butterflies of the North Woods by Larry Weber as a hickory hairstreak. Other hairstreaks look similar and the photo was sent to “butterfly referee” Karl Legler who made the call of a banded hairstreak. We would like to see the name changed to the oak hairstreak because the banded hairstreak caterpillar feeds exclusively on oaks. This individual was found in the bur oak savanna above the west pond.  Next year we will have to remember to check the oak savanna and break our record of one individual. The adults feed on sumac, common and swamp milkweeds, sweet clovers and dogwoods.  

We try to conduct the count the first week in July and find that butterfly numbers can vary greatly year to year. This year we found 2 red admirals (55 last year), 91 common wood-nymphs (8), 191 clouded sulphurs (4) and 72 black swallowtails (4). The full list of species and their counts found this year and since 2014 are in the table shown at the bottom of this post.

We were pleased when Topf Wells and the Hasburghs reported 53 monarch butterflies from 16 acres at Erstad Prairie. Two hundred and seven monarchs were found compared to 107 in 2019. Last year we had a record monarch migration and tagged 2,100 at Goose Pond. Monarch numbers were low in June but picked up in the first half of July. Hopefully monarch numbers will be high again in fall migration.  

THANK YOU to everyone who came out on a hot day to survey for butterflies. We are looking forward to the count next July and hope that masks and social distancing will not be required.

Great Wisconsin Birdathon Count - Columbia County

Print Friendly and PDF

We spent an enjoyable Mother’s Day participating on the Natural Resource Foundation’s Great Wisconsin Birdathon, listing the birds we found and thinking of how our mothers would have loved being part of our Reckless Wrens team consisting of Mark Martin, Sue Foote-Martin, and Jim Shurts. We split up for part of the day between different birding hotspots in order to cover as much quality habitat in Columbia County as possible. In the end, we found 122 species, a record for the Reckless Wrens.

Sue surveyed the Martins' Wildland property near Rio and found 29 species in the 160-acre wetland, prairie, and savanna habitats. Madison Audubon Society holds a conservation easement at Wildland. The feeders were crowded with ruby-throated hummingbirds, Baltimore orioles, rose-breasted grosbeaks, and American goldfinches. Highlights included a pair of trumpeter swans, a prothonotary warbler, and pine siskins. We hope to confirm nesting pine siskins as a first for the Breeding Bird Atlas II in Columbia County.

Sue also found six species of woodpeckers including a red-headed woodpecker in the savanna restoration. Other good finds were the great egret, Wilson’s snipe, black-throated green warbler, orchard oriole, and purple finch. 

Mark and Jim surveyed Goose Pond and Otsego Marsh. Goose Pond Sanctuary was unbelievable! Sixty species were found including 14 species of waterfowl. Waterfowl highlights include a greater white-fronted goose, gadwalls, northern shovelers, northern pintails, green-winged teal, redheads, lesser scaup, buffleheads, a female hooded merganser, and ruddy ducks. 

Jim found what at first he thought to be a female canvasback. The duck was all brown, had a sloping forehead, and as it was swimming with a “purpose”, it appeared tapered in the rear.  Mark had a good look at the bird just when Jim interrupted, “A shorebird just landed in the water!” Forgetting about the duck we had a great look at a male Wilson’s phalarope. Males are dully colored since they incubate the eggs. We could not relocate the unknown duck but from our observations we believe it was a scoter - species unknown.

The highlight of the day was seeing two shorebirds in the distance land in the east pond wetlands. They were black on top and white on the bottom. We had permission and walked to the far edge of the Manthe farm, where we were rewarded with observing a pair of black-necked stilts, an uncommon bird in Wisconsin.

Also found at Goose Pond where horned grebe, American bittern, sora, dunlins, and short-billed dowitchers.

Otsego Marsh was also very productive where we found 39 species. We hiked the trail and began with a female rose-breasted grosbeak carrying nesting material. We found nine of our 11 warbler species at Otsego Marsh including 10 Magnolia, 4 black-and-white, and 2 blackburnian warblers. The highlight was the two male scarlet tanagers that landed close to us. On the water we found four nests and 3 families of Canada geese along with an adult bald eagle and 10 double-crested cormorants.

The three of us checked out Erstad Prairie and Schoeneberg Marsh Waterfowl Production Area, where we found a flock of seven female hooded mergansers, a pair of red-necked grebes, and yellow-headed blackbirds. 

In the county we also added American white pelican, common gallinule, black tern, and Eurasian collared-dove.

It was a very rewarding day to see the results of Madison Audubon Society’s acquisition and restoration efforts. Many birds greatly benefit from the habitat provided.

The Great Wisconsin Birdathon raises funds to support the Bird Protection Fund. Funds raised by the Reckless Wrens are split 50/50 between Madison Audubon and the Bird Protection Fund. (Prior to retirement from the DNR, Sue served on the committee that established the Bird Protection Fund that provides funding for important bird conservation projects. Jim serves on the Great Wisconsin Birdathon planning committee.) If you would like to donate to the Reckless Wrens it is not too late. Ten cents per species would be a donation of $12.20 or you can make a donation of any amount to our team. Thank you for your support!
