birds

Each year hundreds of millions of birds die in the U.S. after colliding with windows. Skyscrapers are not the chief cause, but mostly mid-rise buildings. 

My guide in trying to understand why birds are more likely to collide in three and four-story buildings is Heidi Trudell. She’s an avian collision specialist who works with groups such as Washtenaw Safe Passage.

There are renewed calls to kill cormorants in the Great Lakes. There are far fewer of these migratory birds left in the region after years of lethal control. But anglers and some congressmen say there are still too many and they eat too many fish. Conflict with these waterbirds is longstanding in coastal communtities where fishing is important and the birds nest by the hundreds or even thousands.

In 2004, there were almost 1,800 double-crested cormorant nests on Goose Island, a strip of land in northern Lake Huron about 500 feet wide and less than a mile long.

Amidst concern about animal species on the verge of extinction, we wanted to look at some success stories: species that were highly endangered, but whose populations are now making a comeback in Michigan.

The Kirtland's warbler is one of those species. Fifty years ago, the songbird was nearly extinct. Today, it has an estimated population of around 5,000.

Malaria is incredibly common across the world in mammals, birds, and reptiles. So it's not surprising that birds in Michigan, just like birds elsewhere, suffer from a variety of malaria-causing parasites. 

What is surprising is just how many blood parasites you find in birds with malaria. 

A new study published in the journal Parasitology Research discovered a far greater range of blood parasites than expected in birds tested in southwest Michigan. 

Mornings in Michigan is our series about morning routines and rituals around our state. This time of year, some people get up early to see migrating birds arriving in Michigan. Mike Kielb and his wife sometimes get up at 4 a.m.

People who study birds are now using radar to make maps that can forecast migration at night. They say these maps could help by reducing the number of birds that collide with buildings and wind turbines.

Right now, it’s illegal in the state of Michigan to hunt the sandhill crane, the state’s largest and oldest bird. But a proposal to hunt the species within the state is gaining traction and the U.S. Fish and Wildlife Service says if the state of Michigan asks, it will grant permission to hunt the bird. Michigan would join 15 other states that currently allow sandhill crane hunting. In these states, hunting requires both a state and federal license.

Firearm deer season starts today and thousands of hunters are heading out with their rifles. But around this time of year, there's a tiny group of Michiganders heading out with birds instead.

The pesticide DDT was responsible for wiping out large populations of top predator birds in Michigan and across the country. One of the most well known was the bald eagle whose eggs, thinned by the pesticide, cracked during incubation.

DDT was banned in the 1970s and raptors — with some help from wildlife biologists — started to make a comeback.

New research shows that in order for some early birds to catch the worm, they have to breed sooner in the spring.

Luke DeGroote is the avian research coordinator at Carnegie Museum of Natural History, and he runs the bird banding program at the museum's Powdermill Nature Reserve.

Right now, he’s in the thick of spring migration.

“It’s sort of a bit like fishing, in a way. We put out our nets to see what we catch,” he says.

In the last few weeks, roughly 600 birds have died along the shore of Lake Michigan. They washed up on the beaches within the Sleeping Bear Dunes National Lakeshore, with more dead birds reported on beaches in the Upper Peninsula.

Robins are considered "super-spreaders" of West Nile virus. They’re especially good at passing the virus to mosquitoes, and mosquitoes, of course, can then pass it to us.

It turns out a different bird species – cardinals – might be shielding people from getting the virus in some parts of the country.

Some kinds of birds are doing better in our changing climate, and others are declining. These changes are happening in similar ways in both the U.S. and Europe.

Those are the findings of a new study in the journal Science.

Phil Stephens is a senior lecturer in ecology at Durham University in the UK, and he’s a lead author of the study. 

Stephens and an international team of researchers studied data on more than 500 common species of birds over a 30 year period (1980-2010) in both Europe and the U.S.

You might be aware that the Great Lakes region is a major migratory bird flyway.

What you might not know is that hundreds of millions of those birds will crash into windows and die.

Sarah Reding is part of a movement that’s trying to help reduce that problem. Reding is the vice president of conservation at the Kalamazoo Nature Center.

People who identify birds for the Great Backyard Bird Count logged a record 5,090 species this winter. That’s just about half the bird species in the world.

It’s part of a huge data collection effort each winter. It’s run by the Cornell Lab of Ornithology and the National Audubon Society, and also Bird Studies Canada.

Many birds leave Michigan for warmer weather. But what birds stay here and tough it out with us in the frigid weather?

Macklin Smith, a University of Michigan professor emeritus of English and a veteran bird watcher, tells us which birds we can expect to hear during the colder months.

A recent report from the National Audubon Society points to troubling times ahead for our bird population.

Climate change could make some huge changes for birds in North America: About half of our 650 species would be driven to smaller spaces or forced to find totally new places to live or become extinct – all of this in just the next 65 years.

Jonathan Lutz is the executive director of the Michigan Audubon Society. He says in Michigan, about 50 species are vulnerable to the changing climate.

Like most of us, Dea Armstrong has only seen birds from the ground. Today, she’s going to fly with them.

Armstrong is Ann Arbor’s city ornithologist, and watching birds from a hot air balloon is on her bucket list. I got a chance to tag along to find out what we’d see from the air.

“I’m so excited to see what it’ll be like to look from above and down. I’m pretty sure I’ll be able to recognize the birds, of course, but it’ll be just so different,” she says.

The common tern used to nest in great numbers in the lower Great Lakes region, including Michigan, Pennsylvania, and Ohio. But in recent decades, common tern nests and their brown speckled eggs have largely disappeared from the region. 

If you grew up in Michigan, chances are when you thought of the very first signs of spring you thought of crocuses and robins. 

But have you noticed that in recent years, something has changed– that robins are pretty much with us all through the winter?

Why has this happened, and do we have any reason to worry about robins in this exceptionally harsh winter?

Julie Craves, director of the Rouge River Bird Observatory in Dearborn, joined us.

Imagine walking down a picturesque beach along Lake Michigan, and stumbling upon the carcasses of dead birds. That’s a very real and unpleasant problem along Lakes Michigan, Huron, Ontario and Erie. (It’s not as big of an issue in Lake Superior because of the lake’s colder water temperatures.)

Loons and other deep-diving birds are suffering from a disease called avian botulism. It’s form of food poisoning that kills wild birds in the Great Lakes ecosystem.
