President’s Corner
BY MARTY CORFMAN
Dear Members and Friends,
If you have stepped outside early in the morning this May, you’ve likely heard it: the vibrant, chaotic symphony that tells us May-gration is officially at its peak. Here in Dubuque, our trees and skies are alive with the stunning colors of returning Baltimore Orioles and Yellow Warblers. For birders and nature lovers alike, this is our favorite kind of frenzy—a reminder of the incredible, fragile connections that bind our local habitats to ecosystems thousands of miles away.
I had the fantastic opportunity to spend several days at Magee Marsh in Ohio during the “Biggest Week in American Birding” annual festival. Due to family obligations, I did not participate in any of the formal group or educational opportunities available, but the migrating birds did not disappoint! Seeing the tiny warblers are eye level was such a wonderful change from the reality of “warbler neck” we get looking into our tall tree canopies for these birds.
While May brings immense joy, it also brings responsibility. These nesting and migrating birds face significant hazards. I urge each of you to take two simple actions this month to protect our feathered visitors:
- Keep it Dark: Keep your outdoor lights turned off overnight during spring and fall to help nocturnally migrating birds navigate safely around our town.
- Plant Native: If you are updating your garden or patio this spring, choose native plants. They host the essential insect populations that nesting mothers need to feed their chicks.
I’d like to take a moment to celebrate the accomplishments we’ve enjoyed over this last year. We just finished up our monthly September-May program season, and by all accounts, this year was a real success. Thank you to Bob and Sandy Walton, who have worked hard to identify and recruit programs of such variety and importance to our members and friends in the community. Attendance at these events continues to grow, and I hear often how much people enjoy these unique opportunities for learning. We also just held our annual meeting, at which your board was elected. Thank you to each of our board members for all you do to help DAS fulfill our mission. In particular, I’d like to welcome Paul Winer to the board. His knowledge and experience will be a welcome asset to our group, and you can learn a bit about him in his “bio box” in this newsletter!
Thank you for your continued support, your passion, and your dedication to protecting the natural world we all share. I hope to see you out on the trails!

2026 Duck Waddle
BY BOB WALTON
March 7th found Sandy and me at the Green Island Channel 4 parking lot around 5:20 a.m. to participate in the Dubuque Audubon’s 47th annual spring waterfowl watch. I have always enjoyed the pre-dawn sounds of the marsh and try to be there as much as an hour before the main group arrives at sunrise. This time is probably best described by Aldo Leopold in his Sand County Almanac when he said, “To arrive early in the marsh is an adventure in pure listening…and when a flock of bluebills, pitching pondward, tears the dark side of heaven in one long circling nosedive, you catch your breath at the sound, but there is nothing to see except stars.”
It was totally dark when we pulled into the Channel 4 parking lot and lowered our windows, to be immediately greeted by the raucous call of a resident Canada Goose warning that we were near his nesting territory. His honking was soon followed by more honking and the unmistakable quack of migratory female Mallards as a flock of hundreds took to the air. As the eastern horizon began to glow, the area over the Mississippi had large smoke-like clouds of ducks and White-fronted Geese. As if on cue, a small flock of bluebills (Lesser Scaup) pitched downward with a roar from their wings and landed somewhere in the wetlands to the south of the lot, near the railroad tracks. They were greeted by the trumpet call of Trumpeter Swans, the nasal trill of Sandhill Cranes, and the “pip, pip, pip” of Northern Pintails.
At sunrise a contingent of 26 Duck Waddle participants joined us. With spotting scopes and binoculars, we found Ringneck Duck, Bufflehead, Northern Pintail, American Widgeon, Gadwall, Northern Shoveler, Blue-winged Teal, and Green-winged Teal, along with the Mallards, White-fronted Geese, and Lesser Scaup. Of course, there were the resident Canada Geese, and in their midst was one Mallard-sized Cackling Goose.
Next the group went out Fish Lake Road where we saw large flocks of White-fronted Geese and Mallards, and 6 Sandhill Cranes in a picked corn field. About ½ mile out the road, a flock of over 100 Trumpeter Swans were in a field to the west, flanked by more White-fronted Geese, several Snow Geese, over 200 Northern Pintails, and a Ross’s Goose. Unfortunately, when we reached the parking lot at the end of Fish Lake Road, the wind kicked up and it began to rain, but we did see 4 Northern Harriers and several Bald Eagles.
From Fish Lake Road we drove to the Blakes Lake parking lot on the east side of Green Island. Trees shielded us from the wind, and we ventured about 100 yards out the dike where there were large flocks of waterfowl in the open water. A raft of diving ducks had Lesser Scaup, Ring-necked Duck, Bufflehead, Common Goldeneye, Canvasback, Hooded Merganser, and Common Merganser. In the distance were more Trumpeter Swans, American White Pelicans, and Double-crested Cormorants.
At around 9 a.m., it was time to head to Sabula for breakfast and to check out Sabula’s three lakes. The biggest surprise of the day was when I decided to stop at the North Lake boat ramp. The water was ¾ frozen and was covered by hundreds of gulls and Bald Eagles. We counted 183 eagles sitting in trees, and those on the ice were comical to watch as they attempted to pull frozen shad out of the ice. Another 17 eagles were on the north edge, making the count over 200 eagles—many within 100 yards of our cars! The gulls were Ring-billed Gulls, Herring Gulls, and at least one Iceland Gull.
Following a well-deserved breakfast and hot coffee, we checked out South Sabula Lake, but it had white caps and few waterfowl. On the way back to the main road there were around 100 Common Mergansers, 30 Red-breasted Mergansers, and a dozen Ruddy Ducks on Middle Sabula Lake.
Overall, it was a great “Duck Day!”

Bluebird Monitoring at MOS
BY KEN KISS
Tom Davis and I continue to monitor the bluebird houses at Mines of Spain, and this year we are happy to welcome Lynn Schroeder back to our group! We monitor the 30 houses weekly and maintain our records. Typically we get Eastern Bluebirds, Tree Swallows and Northern House Wrens. Results have been fairly consistent year to year, and we’ll update you with the 2026 results in the fall.

Tree Planting at Mines of Spain
BY MARY LEIGH
Dubuque Audubon purchased four 3-4′ eastern white pine and two 2-3′ white spruce for approved planting at Mines of Spain SRA. Three volunteers planted, caged, and watered the six trees on May 1st.
The trees were divided between the Mines of Spain south entrance and Riprow Valley (two pines and one spruce at each location). We hope these new trees will prove to be a good initial size, growing faster than bare root seedlings, while avoiding the adjustment delay often seen with larger trees.
The cages are to protect these small trees from bucks, who like to rub their antlers on young, pliable trees, removing bark and potentially killing the trees. Once these trees are older, their trunks are no longer so appealing for antler rubbing, and the cages are no longer needed for that purpose.
As a separate issue, deer find eastern white pines to be very tasty, so they’ll eat whatever branches they can reach. The cages are also an attempt to protect some parts of the pines from being eaten, to allow them to eventually get tall enough to have branches that are out of reach for deer browsing. White pines are native and fast-growing (2-3 ft per year or more) and will grow up to 80+ ft tall and 25 ft or more wide. They can live over 100 years in windbreaks but usually have a shorter lifespan due to breaking in wind and ice storms.
Deer are far less interested in browsing on white spruce, so hopefully these trees will retain their lower branches, but the cages are still needed initially as protection from antler rubbing. Deer do not normally eat white spruce unless they can’t find other options, such as during a particularly harsh winter with lots of snow. White spruce are medium to fast-growing (2+ ft per year) and will grow up to 60+ ft tall and 20+ ft wide. They can live 80+ years in windbreaks, and heavy snow and ice storms cause little damage.
Below are photos of mature trees for both species, where the cages were removed many years ago, to clearly show the deer browsing preference!
2024 Tree Planting Follow-up
Some may recall that Dubuque Audubon planted 16 eastern white pine bare root seedlings at Mines of Spain in May 2024. One of the survivors can be found at the south entrance (see photo) near the two larger pines we just added. It may continue to struggle in shady conditions, but we hope that removing competing grass around it this year will help.

2026 Spring Species Count
BY TONY MOLINE
On Saturday, May 9, Dubuque Audubon conducted its annual spring species count. The count covered various areas in Dubuque and Jackson counties. A peer-lead group covered a large portion of mines of Spain state recreation area.
In total, 145 species were recorded for the day. Although overall numbers of birds were down, the number of individual species was in line with typical years. Thank you to all who participated.

Spring Potluck Visitor
BY MARTY CORFMAN
We concluded the spring count with a potluck at Swiss Valley Park. About 15 of us convened for great food, great company, and a pretty decent species count! We added one more upon arrival at the shelter for the potluck—this adorable Barred Owlet! It sat in this tree for nearly the entire gathering, allowing all of us to get good looks (and pics!) before it glided off across the creek. Its presence felt like a gift.

Our Newest Board Member
BY PAUL WINER
After a career in manufacturing that did not allow much time to pursue outdoor activities and hobbies, I have spent my retirement doing the things that I had pushed to the back of my thoughts. Woodworking has been a long-time hobby that I spent a lot of time pursuing, and for a number of years was my primary focus. My current involvement in photography started out as a sideline to woodworking, to get outside and expand my activities. I became a member of the Dubuque Audubon Society after being asked to give a presentation on the Crescent Lake National Wildlife Refuge in October of 2025.
Working with extremely knowledgeable wildlife experts and enthusiasts has been very challenging and rewarding. It has expanded my activities and contacts with people that have similar interests. I am also an active member of the Stewards of the Upper Mississippi River Refuge—a “friends group” for the Upper Mississippi River National Wildlife and Fish Refuge, Savanna District.
