Eagles of Wisconsin (Two Species to Know)

September 7, 2022 rmsallmanngmailcom Leave a comment

Eagles are thought of as regal and majestic birds that soar over the United States. This description pretty much fits the bill to a tee. There are a few different eagle species that make their way into the United States. In this post there is information about which species you can expect to find in addition to identification and other information.

Wisconsin is home to two different eagle species with one that can be found nearly anywhere in the state, and one that is a little more season and location specific.

Bald Eagle

Identification

The adult Bald Eagle is an unmistakable raptor species. They have a brown body with a white head and tail. In flight, they look quite flat as opposed to Turkey Vultures and other soaring species that sport a v-shaped wing pattern known as a dihedral. Bald Eagles have a large yellow bill.

Juvenile Bald Eagles don’t look quite as distinctive with varying degrees of mottled white mixed In with brown. Juveniles still have a noticeably large bill.

Range

Bald Eagles winter in most of the Southern United States and Northern Mexico. They migrate north into Canada and some of the Great Lakes states including Minnesota, Wisconsin, and Michigan. There are many areas where Bald Eagles live year round, most of which are around coastlines, rivers, or other bodies of water.

Diet and Foraging Habits

Bald Eagles eat primarily fish but will also consume amphibians, mammals, reptiles, and carrion. In fact, Bald Eagles can often be seen around landfills searching for scraps, or roadsides searching for roadkill. Two places one wouldn’t expect to see such a majestic bird.

Where to Find This Bird

The easiest way to see Bald Eagles is to watch the skies and look for a large bird with broad, flat wings soaring. In terms of places to see many Bald Eagles at once, search out dams or other places where fish congregate, here, several different Eagles may be waiting to get an easy meal. To see Eagles in their nesting habitat, forests near rivers and bodies of water that are far away from human habitation are the best places.

Golden Eagle

Identification

Golden Eagles are very large raptors that are brown in color with slightly lighter feathers mixed in. They have a white band on the tail, and the nape of their neck has golden colored feathers. Immature birds have white at the base of their primary feathers visible in flight from underneath.

Range

Golden Eagles live year round in the western half of the United States and Northern Mexico. Some members of this species migrate north and breed in Alaska and Canada. During winter, Golden Eagles move east with some birds traveling a significant distance away from their expected area. This species can also be found in Europe and parts of Asia.

Diet and Foraging Habits

Golden Eagles typically eat mammals such as squirrels and rabbits, but they will also eat birds. This particular species has also been known to to take on much larger prey such as deer or even other larger predators such as coyotes.

Where to Find This Bird

Golden Eagles aren’t typically found near human habitation or near large tracts of forest. They are a species of open areas as well as mountainous areas. The easiest way to find them is to look for them soaring over.

In Wisconsin, Golden Eagles are seen annually in Grant County and can be found by driving the roads near the bluffs and watching the sky. They are also constantly reported north along the Mississippi River.

Summary

Eagles are large and noticeable birds. Their regal look and importance as symbols of strength certainly make them intriguing. Knowing which eagle species are expected in your state can be instrumental in identifying which exact species you’re looking at.

Bald Eagle: Back from the brink

July 4, 2021 rmsallmanngmailcom Leave a comment

As far as birds go, there is none more iconic in the United States than the bald eagle. Known as a symbol of freedom, grace, and perseverance, America’s national bird can be seen regularly in most parts of the country; but this wasn’t always the case. Not too long ago, the Bald Eagle was critically endangered and at serious risk of becoming extinct. This is the story of how this regal raptor came back from the brink.

What led to the Bald Eagle’s Decline?

In North America, eagles have always been associated with positive traits. So much so, that in 1782, the Bald Eagle was adopted as a National Symbol of the United States. Even with this bird being a national icon, at this time in history, there was a lot of misinformation about their habits and lifestyle. We now know that this species feeds mostly on fish and carrion, but at earlier eras there was a wide held belief that eagles were a threat to medium sized livestock and even children. As a result, many Bald Eagles were hunted by landowners fearful of losing animals to the large birds. In addition, much of the bald eagles natural prey was also on the decline due to hunting and habitat loss. However, hunting and habitat loss were not the only factors leading to the bald eagle’s decline.

Serious trouble came in the form of a new pesticide called DDT. After World War II, DDT was commonly used to eliminate insect pests such as mosquitos but caused a lot of collateral damage. The chemical would then wash into waterways, fouling entire waterways, including the things that lived in that water. This meant that fish and other animals that Bald Eagles feed on were not only scarcer due to hunting and habitat loss, but also contaminated with toxins. Eagles would consume the contaminated fish and absorb the DDT into their bodies. While DDT wasn’t fatal to the adult Eagles, it was the bird’s eggs that were most adversely effected. The ingestion and absorption of DDT by the adult birds led to the inability to produce strong eggs. As a result, many Bald Eagle eggs were crushed or cracked during incubation leading to a grave amount of unsuccessful broods.

Due to a combination of chemical poisoning, hunting, and habitat destruction, the Bald Eagle was quickly approaching the point of extinction. In 1963, there were a mere 487 breeding pairs left in the lower 48 states.

What led to the Bald Eagle’s comeback?

Recognizing that the Bald Eagle was losing its battle against extinction, the US government stepped in to try and aid in its plight. In 1972 DDT was banned in large part to its negative impact of wildlife (particularly birds), and in 1973 the Endangered Species Act was created. The endangered species prevented habitat destruction as well as the harassment or killing of any species deemed endangered. These steps in addition to reintroduction, nest monitoring projects, and water quality improvement put the Bald Eagle on a pathway to move out of the precarious place they were in as a species.

How is the Bald Eagle doing today?

In the following decades, the Bald Eagle’s numbers began climbing. In 1995 they were moved from the endangered species list and designated as threatened. Twelve years later The Bald Eagle was officially completely delisted on June 28^th 2007. Now, over 70,000 pairs of Bald Eagles live in the lower 48 states and the species as a whole is listed as a species of “least concern.”

The Bald Eagle is one of America’s greatest conservation success stories. With a very stable population of this species in the wild today, this regal national symbol will continue to soar the skies of American for generations to come. Hopefully more success stories like the Bald Eagle will emerge in the ecological war against extinction, and we will get to discuss more birds that have come back from the brink

Why the House Sparrow should be the USA’s National Bird

July 4, 2019 rmsallmanngmailcom 3 Comments

There are few symbols that represent the United States of America better than the Bald Eagle. The image of a soaring eagle is emblematic of freedom, courage, and bravery. While the Bald Eagle has long been accepted as the best choice to represent our country, it has not been without its detractors. Founding Father Ben Franklin had a famous distaste for eagles, once stating this in a letter:

“For my own part. I wish the bald eagle had not been chosen the representative of our country. He is a bird of bad moral character. He does not get his living honestly … besides he is a rank coward: The little king bird not bigger than a sparrow attacks him boldly and drives him out of the district. “

If not the Bald Eagle, then what other bird could possibly be suited for this proud nation? According to lore, Franklin preferred the Wild Turkey as the bird to best represent the United States as he viewed the species as intelligent and cunning. However, there could be one often overlooked species that would be an even better fit: The House Sparrow.

Before angrily closing your laptop, hear me out on this one. The much maligned House Sparrow may have more in common with Americans than first meets the eye.

Shared History

The ancestors of House Sparrows living in the United States today were not native to North America, but rather introduced in 1851 in Brooklyn New York. They were introduced again in San Francisco and Salt Lake City in the 1870s. They found this new habitat suitable and by 1900 had made their way across the entire mainland USA with populations stretching from coastline to coastline.

It’s easy to have ill feelings toward a species that inhabits a land that was not their own, but then again most of our ancestors arrived from other countries as well. Much like the adventurous House Sparrow, many immigrants arrived in New York and California to start their new lives in the United States. The first immigrants that arrived in the United States in 1620 initially struggled in their quest to find a better life. Eventually, their descendants along with other immigrants expanded westward, and much like the House Sparrow began to thrive. As new Americans moved across the nation, so did the House Sparrow, often prospering in areas already inhabited by humans.

Shared Habitat

While most native species spend their time away from human activity, House Sparrows thrive in it. Like other non-native species such as European Starlings and Pigeons, House Sparrows can be found near almost any man-made structure including houses, bridges, brush piles and many more. House Sparrows not only live with humans but also dine with them, frequently eating discarded food scraps and utilizing backyard bird feeders. The fact that these birds have found a way to live right alongside people sets them apart from many other species that inhabit North America.

Well we’d like to believe that we are adventurous and prefer to be exploring the outdoors, in reality, most of us prefer our comfortable nests in the city. This is also true of the House Sparrow as they actually prefer to utilize man-made structures and birdhouses rather than natural tree cavities.

Shared Characteristics

House Sparrows have a habit of being quite nasty to other species. While nesting they will harass any other bird that gets close to their nest and even violently attack nesting birds in an attempt to evict them from nest holes that they want. Many nature enthusiasts harbor disdain for House Sparrows because of this brash aggression toward anything that flies. Bird lovers also despise them due to their tendency to displace native species. However, as human habitation continues to infringe on natural areas it becomes clear that we may have more in common with House Sparrows than we’d like to believe. In 2009 there were nearly 2,000 species of plants and animals listed as endangered in North America. Most of those have habitat loss noted as the primary reason.

Though it’s easy to dwell on the negative correlations between House Sparrows and Americans, there are many things to be proud of when it comes to this bird. They are very social, living in groups communicating with each other often. They display great courage in the face of much larger enemies and fiercely defend their families. They are resilient and adaptive and have found a way to proliferate an entire continent. While the House Sparrow may be a nuisance to other bird species, they do whatever it takes to ensure the survival of their own species. Surely that is found in human beings as well.

Final Thoughts

The House Sparrow is an impressively adaptive species that carved out a niche for itself in a land it didn’t originally belong in. They have successfully found a way to co-exist with human beings and have withstood the freezing winters and harsh summers of the North America to live in nearly every state. The House Sparrows defends itself and its family with courage and ferocity even in the face of a much larger foe.

While the House Sparrow gets a bad rap, If one looks below the surface, it’s easy to see ourselves in this species even if we don’t want to admit it. This little bird has beaten the odds; ascending beyond its small stature to become a fixture in many North American environments. With a story similar to our own, this formerly European species is now just as American as we are. For that reason, the House Sparrow would be the perfect National bird for the United States.
