Iowa is one of the most important wintering grounds for Bald Eagles with thousands of the huge raptors moving into the state from the north to join our resident breeding birds. Wisconsin, Minnesota and Michigan all have some of the highest densities of nesting Bald Eagles in the lower 48 states and many of those eagles, especially from MN and WI move into Iowa during the winter months and frequently gather in large numbers around areas of open water to feed and roost.

Since the early 1990s, the Iowa DNR, plus a small army of volunteers has recorded this phenomenon during the Bald Eagle Midwinter Survey that takes place in the first two weeks of every year.  Surveyors scope the trees, air and ice for Iowa’s largest raptor while driving snowy roads which wind along next to many of Iowa’s biggest rivers.  There are 52 set routes in Iowa that cover over 1500 miles in 45 counties and along at least 13 rivers.  The 2019 survey was run from January 2nd through the 16th and was mostly characterised by extremely mild winter temperatures and weather leading up to the survey.  The average percentage of river covered with ice was only 18%, the lowest since 2007 and most surveyors indicated that the weather was “mild” to “very mild”. Hard to believe coming out of the polar vortex!

What did all this mild weather mean for the eagles?  There were fewer than last year’s close to record numbers but at 2,924 there were still plenty of birds counted.  When the weather is mild and rivers are open, we expect fewer birds to be counted because birds from up north may not feel driven to move south to look for food and the birds that are here are more spread out, making them harder to count. Also, at least four routes could not be surveyed because of the federal government shutdown.

The count of birds is usually split into adult and immature (and some unidentified) and those totaled 1,893 adults and 952 immatures.  This is important because the percentage of immatures in the population is a metric we use to make sure that successful reproduction is happening.  The percentage this year was 32.6%, almost identical to 2018’s percentage and it has been stable since 1994.

Notable this year, was the Missouri River, which had its highest count ever with 498 bald eagles counted!  The second highest count was in 2012 and was only 195.  The Mississippi and Des Moines rivers tend to have the most birds and while they were highest again this year, the Missouri came in a close third.

The data collected on Iowa’s bald eagle midwinter survey show an upward climb of eagle numbers from 1994 to 2019.  It’s an important survey for the annual trend it provides and along with eagle nest monitoring helps the Iowa DNR keep an eagle eye on this important species!

The Bald Eagle Midwinter survey is a national survey, currently coordinated at that level by the Army Corps of Engineers. The Corps analyzes data from the many states that participate which allows them to have an idea about eagle population trends at the regional and national scale. These type of data played a key role in determining in 2007 that the Bald Eagle was doing well enough to be removed from the Endangered Species List.

Spring Migration Paddling

There are many area’s in Iowa that are perfect opportunities to paddle plus view returning or migrating water fowl. One such area is Chichaqua Greenbelt Bottoms, located 30 minutes from Des Moines.

Chichaqua Greenbelt Bottoms is a 24-mile stretch of the old meandering Skunk River channel between the northwest end of the park boundary and the Polk-Jasper County line. It’s not just the birds that make it special.

Since 1960, Polk County Conservation in partnership with other organizations acquired more than 9,000 acres of land along the old Skunk River River corridor, preserving and protecting wetlands, such as, old river channels, backwaters, marshes, upland potholes, side hill seeps, alluvial floodplains, and upland drainage ways.

Marsh habitats are great for birds, especially migrating waterfowl that stage and rest while traveling through our state. Bring along a camera, dry bag and bird book and enjoy a day on the water identifying non-resident spring visitor species.

Two other great Marsh areas are in Northern Iowa in the Sunken Grove/Shimon Marsh Wetland Complex in Pocahontas County near Fonda. It is a birding/paddlers paradise in early to mid April. They are located 1-2 miles west of Fonda, just off of Hwy 7.

Another great paddling and birding area is Sweet Marsh, located in Bremer County in the Northeast part of Iowa between Tripoli and Sumner. It has a summer breeding population of Sand Hill Crane as well as large flocks of migrating, breeding White Pelican, Trumpeter Swan and large populations of water fowl that can be seen from March end when the marsh waters thaw until April end when migration wraps up.

Frog and Toad Survey Workshop

All across the state of Iowa, citizen scientists are making enormous contributions to wildlife conservation with some training through the Iowa Department of Natural Resources’ (DNR) Volunteer Wildlife Monitoring Program.

“The Volunteer Wildlife Monitoring Program provides an opportunity for adults who love the outdoors and wildlife to be directly involved with the conservation and monitoring of Iowa’s resources. The work done is crucial to the well-being of these species,” said Stephanie Shepherd, wildlife biologist with the Iowa DNR’s Wildlife Diversity Program.

Every March and April, Shepherd travels around the state to lead training workshops that ready folks to collect data on some of Iowa’s critical wildlife. So what are these critical wildlife species?
Volunteers are trained to listen to and recognize the 16 species of frogs and toads in Iowa based on their breeding calls. In 2018, volunteers surveyed 54 survey routes which translate into more than 400 wetland sites monitored for frog and toad activity.

“The frog and toad surveyors are particularly special because to perform the surveys volunteers have to drive back country roads at night along a specific route using only their ears to collect data,” Shepherd said. “I think most feel that exploring the Iowa wilds at night is a unique experience and opportunity.”

Interested volunteers must register for and attend a training workshop.

Trumpeter Swans 101

Trumpeter Swans were once common in Iowa, but the last wild mated pair nested in Iowa in 1883. They were completely gone from the state by the late 1880s. They were prized for their meat, skin and beautiful pure white feathers. By the early 1930s, only 69 remained in the lower 48 states.

In 1998, a wild pair were spotted in Dubuque County and hatched 3 that year.  In 1999, the pair hatched 5 and again in 2000.  Iowa DNR have been active in Trumpeter Swan releases. Interestingly, it has been found that released Swans do not migrate far from their release site. It has only been the past twenty years that they have rebounded through many conservation efforts. Trumpeter Swans are considered a conservation success story by many. However, they do have current threats with habitat loss, lead poisoning, power line accidents and are occasionally shot. It is illegal to hunt Trumpeter Swans.

These beautiful all-white birds are the largest North American waterfowl species. They can weigh from 25- 32 pounds with an average 8-9 foot wingspan. They have black beaks and black legs. They are often confused with Tundra Swan. The Trumpeter Swan’s scientific name, Cygnus buccinator, is from the Latin Cygnus (swan) and buccinare (to trumpet).

The male and female mate for life. If the male loses his mate, he often does not take a mate again. In the wild, they live to be up to 24 years old and in captivity around 33 years. Mating does not occur until they are at least three years old. Egg laying begins in late April or May with 4-6 eggs hatched being average. The eggs take 32-37 days to incubate and young take 90-120 days to fly after hatching. Their breeding habitat consists of large shallow ponds, undisturbed lakes, pristine wetlands and marshes. They use the same nesting site year after year. Their adult summer diet consists of aquatic plants with a winter diet of farm field grains and grasses. In a group, they fly in a V-shaped pattern. They are very affected by human disturbance and will abandon a nest if disturbed. They typically will nest within 600 feet of shore and need at least 100 yards of open water for take off to fly.

An estimated 160 trumpeter swans are currently wintering at the Dale Maffitt Reservoir and surrounding area southwest of Des Moines. This provides a rare opportunity to view good numbers of free flying Trumpeter Swans. Visit them soon before they move onto other areas.

Trumpeter Swan can also be spotted while paddling or hiking at Sweet Marsh Wildlife Area in Bremer County in the early spring.

Becoming An Outdoors Woman: Save the Date: May 3-5, 2019

Becoming an Outdoors Woman workshop now accepting registrations

Registration is open for spring Becoming an Outdoors Woman workshop, May 3-5, originating from the PZAZZ! Convention and Events Center, in Burlington.


While the focus of BOW is primarily for women, the workshop is an opportunity for anyone 18 years or older to learn outdoor skills.”This workshop is all about introducing new participants to the outdoors and building social support networks so skills learned can be applied to other outdoor opportunities throughout the year,” said Rachel Ladd, with the Iowa Departments of Natural Resources.  “It’s an excellent opportunity to try activities under the guidance of our top-notch instructors.”
Workshop courses include wilderness survival, outdoor photography, intro to archery, kayaking basics, orienteering, pistol basics, Dutch oven cooking, kayak fishing, explore bow hunting, backpacking and hiking, intro to fishing, canning, wild game and fish care, boater education and more. Attendees taking intro to fishing, kayak fishing or talking turkey hunt are required to have purchased a valid Iowa license prior to arrival.


A Friday evening auto tour through Heritage Hill National Historic District will highlight many architectural periods and styles in nearly 160 structures in the northern sector of downtown Burlington, and its most famous landmark, Snake Alley.


A Friday night reception, sponsored by Aldo Leopold Pheasants Forever Chapter and Parkside Brewing, will connect Iowa’s wild pheasant population and bees, and pollinators role in the art of brewing.


The cost of the workshop is $330 (single occupancy), $280 (double occupancy), and $250 (no lodging) before March 29. After March 29, registration is $300 and will not include lodging. The fee includes program materials, equipment, lodging and meals. Enrollment is limited to 115 participants. A limited number of $140 scholarships are available.


“Make sure to choose one class for each session, each class will show the number of seats still available and once a class has filled, it will be closed. Attendees will know what sessions they are in at the completion of the registration process,” Ladd said.


Early registration is encouraged as enrollment is limited and workshop spaces and lodging fill quickly.  Go to to download a registration form, select classes and for more information on applying for a scholarship.


The event is being held in partnership with the Greater Burlington Convention and Visitor’s Bureau, the Des Moines County Conservation Board and the Iowa DNR.

“Chickadee Check Off” or Fish / Wildlife Diversity Fund

Last year, a little over 7,500 Iowa taxpayers helped boost wildlife conservation with donations to the Fish and Wildlife Fund on their state tax form. This is roughly 400 fewer contributors than in 2016. Donators represent about 0.4% of total tax payers in Iowa.
“We are so thankful to all the people who choose to donate to wildlife conservation with their tax refunds,” said Shepherd. “I have a hope that we can do even better to increase funding levels which go directly to habitat development and restoration programs for some of Iowa’s most vulnerable animal species. The funds are so important for natural resources.”

The Fish and Wildlife Fund, known popularly as the “Chickadee Check-off,” is a mechanism the Iowa Legislature created in the 1980s for Iowa citizens to donate to wildlife conservation on the Iowa state tax form. Before this time, so called “non-game” wildlife had no dedicated funding. Non-game wildlife are the 1000+ species such as songbirds, bald eagles, salamanders, turtles, monarchs and bees that make up the majority of wildlife in Iowa. It is one of the only funding sources for the Department of Natural Resources’ Wildlife Diversity program which is responsible for all these species. The program uses the funding to help improve wildlife habit, restore native wildlife, provide opportunities for citizens to learn about our natural resources and much more

According to Shepherd, Iowans donated roughly $145,000 last spring when completing their 2017 tax forms. This translates to an average gift of $19.25 per donor. The number of donors has mostly stayed level or decreased but thanks to more generous giving, the amount donated has also stayed level or even increased.

The tax check-off line is pretty inconspicuous and can be easy to pass over or forget. “Many tax preparers may not remember to ask whether a client wants to donate,” said Shepherd. “It may be up to the taxpayer to remind their preparer, or make a point of looking for it whether they are doing their form on paper or electronically.”
Once you find the check-off, donating is easy, according to Shepherd: simply write the amount to donate next to the Fish and Wildlife Check-Off, line 57 on Form 1040, and the sum is either automatically deducted from the refund or added to the amount owed. As with all charitable contributions, the amount is deductible from next year’s taxes.

If every Iowa taxpayer donated just $1, it would mean $1.5 million for wildlife and natural resource conservation!

US Fish and Wildlife Report: USFW Fisheries received three Pallid Sturgeon in December to help with species recovery


Pallid sturgeon are bottom dwelling, slow growing fish that feed primarily on small fish and immature aquatic insects. This species of sturgeon is seldom seen and is one of the least understood fish in the Missouri and Mississippi River drainages. It is an ancient species that has existed since the days of the dinosaurs.

The recovery efforts include research to learn more about its life history and habitat requirements, artificial propagation to improve its numbers, habitat improvement and reducing mortality from commercial fishing.

Species Description: The pallid sturgeon has a flattened, shovel-shaped snout, possesses a long, slender, and completely armored caudal peduncle, and lacks a spiracle and belly scutes. Pallid sturgeon are bottom-oriented species. Pallid sturgeon can be long-lived (40+ years), with females reaching sexual maturity later than males. Pallid sturgeon at the northern end of their range can obtain sizes much larger than fish at the southern end of their range.

The pallid sturgeon experienced a dramatic decline throughout its range since the mid to late 1960’s. Nearly all of its habitat has been modified through river channelization,
construction of impoundments and related changes in water flow. These changes blocked the pallid sturgeon’s movements, destroyed or altered its spawning areas, reduced its food sources or its ability to obtain food, and altered water temperatures and other environmental conditions necessary for the fish’s survival.

Species Factsheet:

Location: Pallid sturgeon are found only in portions of the Missouri and Mississippi River basins. More specifically, the species is known to occur in the following areas:
  • Missouri River in Iowa, Kansas, Missouri, Montana, Nebraska, North Dakota, and South Dakota
  • Mississippi River in Arkansas, Kentucky, Illinois (downstream from Melvin Price Locks and Dam), Louisiana, Mississippi, Missouri (downstream from Melvin Price Locks and Dam), and Tennessee
  • Platte River in Nebraska downstream of Elkhorn River confluence
  • a portion of the Kansas River downstream from Bowersock Dam
  • Yellowstone River in North Dakota and Montana downstream of the Bighorn River confluence
  • and the Atchafalaya River in Louisiana
    Habitat: Mississippi River downstream of its confluence with the Missouri River; Ohio River below Dam #53; Missouri River
There have been occasional observations in the lower Big Sioux River of South Dakota, the Grand River in Missouri, and the Mississippi River near Keokuk, Iowa.
