Gull Watches

When: Sunday mornings November 11, 18, 25 @ 10am

Where: Superior entry breakwall (very end of Wisconsin Point)

Contact: Clinton Nienhaus –


If you have ever wanted a chance to spend time in the field to learn gulls, this event might be for you! Join obsessive gull watcher Clinton Nienhaus on this joint MOU/DAS Superior Entry Gull Watch. This field trip has the intention to view and learn about gull identification in the field, less about listing.

Gulls can be a difficult group of birds to identify, but this field experience will work to help attendees better understand the more common gulls in Minnesota, as well as give pointers on how to spot the more uncommon species of gull that make their way to the state every fall and winter.

Targets for this trip would include Iceland gull (Thayer’s and Kumlein’s), Glaucous Gull, Great Black Backed Gull, and maybe even a shot at a 7 gull species day with something rare mixed in!

Meet at the Superior entry Breakwall (very end of Wisconsin Point) at 10:00 AM. The gulling
could last between 2-4 hours, depending on the gulls. Bring cameras, binoculars, and spotting scopes. If possible, bring one loaf of bread or more (for the gulls!). Dress according to the weather. This is a stationary event that will not have any bathroom breaks or lunch stops, so bring snacks and water as needed. RSVP required: RSVP to Clinton Nienhaus at

Report from November 11,2018: Superior Entry Gull Watch:

This is my 3rd year doing stationary gull watches at Superior Entry. The intention of this event (which is ongoing) is to spend time with and learn gulls. With nearly 350 gulls present on the 11th, there was plenty of learning to be done! Somewhat disappointing was species diversity, with only one adult Thayer’s Iceland Gull (photo below) and 8 Ring-billed gulls to break up the Herring Gull party. Nonetheless, we were able to learn and check out a representative or two of every age class of both Herring and Ring-billed Gulls! The biggest surprise of this trip was the sheer number of Bald Eagles present, which really can make gulling tough. There were no less than 20 Bald Eagles loafing around and chasing gulls during our time at Superior Entry! The other significant species most of the group got to see was a pretty strong showing of… Sea Ducks! We had a total of 13 White-winged Scoters and 1 Black Scoter fly by the entry while we were watching gulls. A nice treat for the group, even if they were a little distant. As I said, these Gull Watches continue on November 18 and 25, starting a 10 am. If you are interested, send me an email at

North Shore Sea Duck Field Trip

Report from November 10, 2018 North Shore Sea Duck Trip:

This was the 4th trip I have lead searching for ducks along the North Shore and it was arguably the best one yet! For the first time ever we had a scoter slam… and nearly a sea duck slam (all 3 scoters, Long-tailed Duck, and Harlequin Duck), as the group narrowly missed Harlequin Duck. Non-duck highlights for this trip included a total of 41 species, with a late Savannah Sparrow in Two Harbors, nearly 20 Rough-legged Hawks between Iona’s Beach and Grand Marais with 4 total dark morphs, and lots of Snow Buntings along the roadside. Sea duck totals include: 5 White-winged Scoters (Taconite Harbor, Grand Marais Harbor), 2 Black Scoters (Taconite Harbor, Grand Marais Harbor), 1 Surf Scoter (Grand Marais Harbor to complete the slam!), 148 Long-tailed Ducks (139 at Good Harbor Bay), and almost a Harlequin Duck at Grand Marais Harbor, seen earlier in the day by Ise et al and briefly by Aaron during our visit, but we couldn’t refind it. All in all, a long day, but super productive considering the distance covered!

Birding by Hindsight: A Second Look at Identification

The Common Nighthawk in northern Minnesota

September 13, 2018 – Presented by Steve Kolbe

The Common Nighthawk (Chordeiles minor), like other species in the nightjar family, is a low-density breeder in the boreal forest and is not adequately surveyed by point counts due to its secretive nature and crepuscular activity.

However, large numbers of this species occur each autumn along the north shore of Lake Superior. With average annual counts of nearly 19,500 individuals, the autumn migration of Common Nighthawks is the largest known concentration of this species in the world.

While the precise geographic origin of these migrant birds is unknown, many arrive from the Canadian boreal forest, where this species has undergone a significant decline and is listed as threatened. Trend analysis from autumn migration counts does not show such a decline.

The annual autumn count of migrating Common Nighthawks along the north shore of Lake Superior is likely the best and most cost-effective way to census the boreal forest breeding common nighthawks and determine population trends for this declining aerial insectivore.

Birds of Minnesota’s Big Bog Forests

Presented by Josh Bednar, Natural Resources Research Institute

February 8, 2018

Minnesota’s lowland conifer forests provide multiple ecosystem services and habitat for hundreds of species of wildlife. Disturbances such as logging, insect outbreaks, fire and climate change have the capacity to significantly alter bird communities in lowland coniferous forests. Our objectives were to document breeding bird habitat use in black spruce (Picea mariana), tamarack (eastern larch, Larix laricina) and white cedar (Thuja occidentalis) forests in Minnesota. Breeding birds were sampled at 130 points systematically distributed throughout dominant lowland conifer cover types within the Agassiz Lowland Subsection (ALS) of northern Minnesota. Species such as the Connecticut Warbler (Oporornis agilis) and Boreal Chickadee (Poecile hudsonicus) were highly associated with black spruce-tamarack bogs while other species such as the Nashville Warbler (Leiothlypis ruficapilla), Yellow-rumped Warbler (Setophaga coronata) and White-throated Sparrow (Zonotrichia albicollis) were ubiquitous across many lowland conifer forest types. These findings can inform forest and wildlife management decisions that will benefit the conservation and management of breeding birds in lowland conifer forests.

Hummingbirds are one of the most fascinating families of birds on the planet. Their diminutive size, glittering colors, frantic actions and amazing variety of form insure their popularity wherever they occur.
While the world has around 350 different varieties of hummingbirds, Minnesota, like all of the Eastern U.S., is treated to only a single species that occurs commonly. Traveling to the Southwestern U.S. could net you dozen or more species, and Costa Rica may get you over 30, but to see a LARGE number of hummingbirds you need to visit South America. Hummingbirds reach their peak diversity in South America, and you can expect to see 70+ species on even a short visit. (We’ve seen as many as 80 species on a single, two-week trip in both Colombia and Ecuador!)
Here in the North Woods, our feisty Ruby-throated Hummingbird is a woodland gem that captivates everyone attention. Would you like to learn more about hummingbirds? We’ll introduce you to our familiar Ruby-throated Hummingbird and show you how to attract them to your yard. What plants work best? What about hummingbird feeders? Does the nectar need to be colored red? Is it possible to have hummingbirds nest in my yard? Answers to these questions and more will be discussed during the program.
Discover hummingbirds from around the world. Tropical hummingbirds are truly amazing in form, function and coloration. Evolution and sexual selection have created physical specimens that often defy belief. Many gaudily colorful, some ornately feathered and others just downright strange.
Photographing these ornamental sparklers offers a unique challenge. Kim and his wife, Cindy, have photographed hummingbirds from Alaska to South America. Do you think you might like to photograph hummingbirds? Kim will share his experiences and offer tips on photographing these avian jewels.
Join us for a fun, informative, photo-filled look at hummingbirds!

North Shore Sea Duck Trip
with Clinton Nienhaus

Saturday, November 11, 2017

Duluth Audubon has recently added a now staple trip to the late season field trip season: the North Shore Sea Duck Trip! This is the third year of the trip and each year we have succeeded in finding our targeted species: Sea Ducks! The sea ducks include diving ducks that are not seen regular in the US outside of the Great Lakes and the East and West coasts. The ducks include the eiders, scoters, Long-tailed, and Harlequin ducks. This trip, we were able to find a total of 6 White-winged Scoters and numerous Long-tailed Ducks. Other sea ducks did elude us, but we were able to add a couple of rarer species to the trip, including Townsend’s Solitaire (in two locations!), Rusty Blackbird (a bit on the late side), Western Meadowlark (annual in the fall, but still uncommon), and a pair of late Yellow-rumped Warblers. This long day trip, starting in Duluth and ending in Grand Marais was attended by a total of 8 folks, an average showing. Fun was had by all on a beautiful day for a drive up the North Shore!
