Bald eagle nest found in Milwaukee County for first time in decades
And then there were 72.
The a long time-lengthy comeback of the bald eagle in Wisconsin experienced checked just about every box but a single.
The vacant spot was geographical: Our national symbol had been documented nesting in each and every county in the state except Milwaukee.
But this 12 months the significant, handsome birds have filled in that blank. And with a prosper.
Biologists and chook conservationists built it formal Wednesday with the announcement that at the very least one active bald eagle nest had been documented in the state’s most intensely-created and urban county. The web site is on public land in southern Milwaukee County.
The news was shared jointly by the Department of Normal Sources, Madison Audubon and Milwaukee County Parks Section.
“Super interesting,” mentioned Sharon Fandel, DNR area ecologist. “We have been having nearer and closer, and now we can say it can be truly took place.”
Beth Martin of Lake Geneva, a volunteer with Madison Audubon’s Bald Eagle Nest Look at method, was among the several people monitoring the internet site in current months and provided pictures of the strong, white-headed birds on the nest.
A pair of eagles created the huge stick structure in 2021 but didn’t nest in it, said Brian Russart, Milwaukee County Parks Natural Areas Supervisor.
This year eagles returned and have been observed sitting on it all around-the-clock, indicative of egg tending.
As these kinds of it fulfills the definition of an lively nest as opposed to sites where eagles construct or frequent a acceptable structure but don’t lay eggs.

And what is actually far more, eagles have been noticed this 12 months working on three other nests in Milwaukee County, Fandel reported. A single is on general public land in the southern part of the county, one particular on non-public land in the east-central and a single on private land in the northeast.
It really is too early to say no matter whether these websites will host active nests this yr, but a volunteer Wednesday noted “egg rolling” at the northeastern Milwaukee County location.
So the county active eagle nest count might nicely go from zero to many in the initial calendar year.
“It’s been awhile, but it seems like it can be genuinely coming collectively,” Russart reported.
Officials are not providing locations of the nests to support secure the birds from becoming harassed.
The documentation of the nesting in Milwaukee County is the hottest optimistic milestone for eagles.
The inhabitants of the species was in trouble just 70 years in the past. Eagle figures dropped to less than 1,000 in the United States because of unregulated searching, poisoning and then, in the article Entire world War II era, the use of DDT and other chemicals.
DDT triggered eagles and quite a few other birds to lay thin-shelled eggs that broke prior to the chick hatched. With extremely minimal recruitment rates, eagle figures plummeted.
After DDT was prohibited by legislation – Wisconsin was the to start with to ban its use in 1972 – and with protections below the Endangered Species Act starting up in 1978, eagles began to mount a comeback.
Bald eagles have been taken off from the state endangered species record in 1997 and the federal list in 2007. They are still shielded less than the Bald and Golden Eagle Protection Act and other federal legislation.
The 2019 Wisconsin bald eagle and osprey nesting report (the most recent obtainable thanks to COVID-19 checking limits the last two yrs) lists 1,684 occupied eagle nests in the point out.
In 1974, there were being 107.
The birds, identical to gray wolves, are exceeding predictions from many years in the past and now occupy breeding territories in sections of the Badger State beforehand regarded as unsuitable for the species.
“This remarkable comeback has caused us to rewrite a whole lot of the story of eagles in the state,” reported Sumner Matteson, DNR avian ecologist.
The Madison Audubon eagle nest observe method has provided a substantial support to the DNR as it keeps tabs on the expanding populace.
The citizen-science software, commenced in 2018 on a dozen nests in Dane County, has expanded to about 115 nests in 26 counties this 12 months, claimed Brenna Marsicek, Madison Audubon’s director of communications and outreach.
By virtue of volunteer observations, the nest observe delivers a detailed appear at the eagle’s production cycle, from nest constructing and copulation to egg tending and feeding eaglets to fledging.
It complements the DNR preset-wing aircraft nest counts, Marsicek claimed.
“Our volunteers get a really comprehensive story, which include if the nest fails or how lots of birds are fledged,” Marsicek mentioned.
Bald eagles are extremely sensitive to disturbance for the duration of the nesting season (February by means of June) as they function to increase their younger.
It truly is not just proper and moral to keep away from harassing nesting eagles — it’s enforceable by law.
In accordance to federal regulation and the Bald and Golden Eagle Safety Act:
· Everyone observing, photographing, or existing near a bald eagle nest must keep on being 300 toes or much more away from the nest to protect against disturbance and stay away from producing the eagles to abandon their nest.
· Use of drones at nest web-sites are strictly prohibited, as they are thought of particularly disruptive to the nesting pair.
· Observers ought to keep away from agitating or flushing the eagles from the nest, and decrease the use of flash pictures. All of these safeguards foster a risk-free environment for the eagles and eagle enthusiasts.
The eagle nests on community land demonstrate that efforts to protect and take care of purely natural spots in the state’s biggest city park procedure are paying out off for wildlife, Russart reported.
In distinct, initiatives to conserve large trees, deliver clean water and native habitats are important to the eagles.
“It’s a significant rationale why the park procedure was specified Wisconsin’s latest Essential Chicken Location (IBA) various yrs in the past,” Russart explained.
With the addition of 1 or extra Milwaukee County eagle nests this calendar year, biologists may be compelled to as soon as additional adjust their expectations for the statewide carrying capacity for the species.
“It’s type of surreal to glimpse back again and see just how far eagles have appear, and a testament to what can be accomplished to protect and restore a species,” Fandel reported.
