Bovine TB in Michigan Beef Herd

Bovine TB found in Alcona County herd
Routine surveillance testing recently revealed bovine tuberculosis in a large beef herd in Alcona County. It is the 73rd cattle herd identified with bovine TB in Michigan since 1998. In Michigan’s modified accredited zone, which includes Alcona, Alpena, Montmorency and Oscoda counties, bovine TB, an infectious bacterial disease primarily affecting cattle, is endemic in the free-ranging white-tailed deer population.

Annual surveillance and movement testing are required of cattle producers to help catch the disease, early, and prevent it from being moved off farms.

“In the modified accredited zone, anything shared by deer and cattle can be a potential source of bovine tuberculosis infection,” Nancy Barr, assistant state veterinarian, said in a recent news release. “Preventing deer from having contact with cattle feed, feed storage or watering areas is crucial for farmers in this area of Michigan and a part of wildlife biosecurity programs being implemented.”

Michigan Hunters: Know Your Does!

By Glen Wunderlich

As we deer hunters take to the woods and fields for opening day of firearms deer season November 15th, we become a throng of wildlife managers no matter the result.  As with any management practice, we have room for improvement.  Accordingly, a look at the most recent verifiable statistics through year 2016 relative to how we’re doing is a good place to start on the path to betterment.

Ardent hunters understand that allowing deer to mature is a worthy goal.  However, if we consider the fact that Michigan hunters continue to kill one of the highest percentages of yearling bucks in the country (1 ½ year-old antlered deer), we certainly are not allowing them to get old.  In fact, close to half of all bucks taken in 2016 were yearlings!  Maybe it’s time to consider another option to fill that freezer:  does.

Michigan’s antlerless take of 145,054 was up 6 percent compared to the previous season but down 15 percent compared to the 5-year average.  Some of that may be attributable to the fact that Michigan’s hunting community has shrunk 14 percent over the past five years.  At the same time, if we were to concentrate our efforts on taking more does, we’d be allowing more bucks to live another year or more.  Realizing that some may want to claim bragging rights for bagging a buck, our combined “achievements” are nothing to brag about compared to other regions of the nation.

Disturbingly, Michigan hunters are killing fawns at the rate of 26 percent of the total antlerless harvest – a sign that indicates hunters need a better understanding of distinguishing fawns from adult does.  To make matters worse, many buck fawns are mistaken for adult does – a sure way to reduce the potential for more mature bucks in the herd.

Identifying Does

There are several easy ways to differentiate between does, doe fawns and buck fawns and a sensible place to start is with good binoculars to determine detail.

Obviously, the best way to compare deer is when they are grouped together.  A mature doe will be more observant – a sentry, if you will.  On the other hand, fawns tend to be more playful and will feed without paying attention to their surroundings.  Fawns also have a shorter nose compared to an adult doe’s head.

Lone antlerless deer are typically buck fawns or commonly referred to as button bucks.  Here’s where the binoculars come in handy:  At this stage of the season, an observant hunter should be able to see developing antler bases or pedicles (immature antlers) giving them the name “button” bucks.  Buck fawns also have a head that is squarer than others.

Just because a group of antlerless deer may contain one larger one, doesn’t necessarily mean it’s an adult doe.  Again, use your glass or hold your fire.

By taking more female deer, we will have done our part to balance the herd and to promote the quality of hunting we all seek in future years.  Be safe, get those deer checked, be respectful of others, and good hunting.

Michigan wetland restoration projects up and running

As part of the DNR’s efforts to restore wetland habitat at sites around the state, restoration projects in Gratiot and Osceola counties are well under way.

At a site known as Potato Creek in Gratiot County’s Gratiot-Saginaw State Game Area, initial construction on a 60-acre wetland restoration project is complete.

“The Gratiot/Saginaw site was a cornfield, and we’ve converted it back to a wetland,” said Steve Shine, DNR wetlands mitigation bank administrator. “It is greening up with the temporary seeding, and the basins are filling with water.”

In the spring, seeds planted this fall for dormant seeding will germinate, and shrubs will be planted.

Restoration and vegetation are complete on a 52-acre wetland project in Sears (Osceola County). A cooperative effort with the U.S. Fish and Wildlife Service’s Partners for Fish and Wildlife Program, this work took place on private land, and a permanent conservation easement will ensure the wetlands never will be converted to another use.

Help FeederWatch Survey the Health & Behavior of Backyard Birds

Ithaca, NY—It’s amazing what we can learn when tens of thousands of eyes are focused on one thing. Those eyes don’t miss much. For more than 30 years, people who feed wild birds have been reporting their observations to Project FeederWatch at the Cornell Lab of Ornithology. FeederWatch participants turn their hobby of feeding birds–a hobby more than 50-million strong in North America–into scientific discoveries. Their reports help scientists better understand what happens to birds facing challenges such as climate change, habitat loss, and disease.

The 2018-2019 season of FeederWatch kicks off on November 10.

The spread of House Finch eye disease is a clear example of the value of this citizen science project. First reports of the disease came from sharp-eyed FeederWatchers in 1994. The Cornell Lab has been tracking the disease ever since by collecting vital information about sick birds from FeederWatchers. From that data, Cornell Lab scientists know the disease is spreading beyond House Finches.

“We’re finding other finch species are being affected,” says FeederWatch leader Emma Greig. “This includes feeder favorites such as the American Goldfinch, Purple Finch, Lesser Goldfinch, and Evening Grosbeak. Not only that, the pathogen that causes House Finch eye disease is becoming stronger and more dangerous. These stronger strains are nearly twice as deadly to the birds.” Read more

Study Finds Mountain Birds Are on an Escalator to Extinction

Ithaca, NY—Warmer temperatures are pushing mountain-dwelling birds ever higher as they try to stay in their comfort zone. That’s the conclusion of a group of scientists who retraced the steps of a 1985 expedition in the Peruvian Andes and documented how birds had shifted in the intervening 30 years. The new study also shows that species that were already living on the ridge-top now have smaller ranges and some have disappeared altogether compared with the 1985 survey. The study, by University of British Columbia and Cornell Lab of Ornithology scientists, appears in Proceedings of the National Academy of Sciences today.

“Mountaintop species are running out of mountain,” says Benjamin Freeman, lead author and postdoctoral fellow at the University of British Columbia. “The next step is extinction. Of the 16 mountaintop species found in the last survey, 8 are missing from our new survey.”

The researchers believe there is a high statistical probability that at least four species have been extirpated from the survey area, given the team’s extensive field searches and analyses of audio recordings. The missing birds are the Variable Antshrike, Buff-browed Foliage-gleaner, Hazel-fronted Pygmy-Tyrant, and Fulvous-breasted Flatbill. Though none of these species is considered threatened and they are fairly widespread, this research supports the idea that birds living at higher altitudes in the tropics are moving even higher as a reaction to climate change which can result in local extinctions.

Michigan Mountain Lion Sighted

By Glen Wunderlich

In the past 10 years, the Michigan DNR has confirmed a total of 38 reports of mountain lions with all but one occurring in the Upper Peninsula – the last one being October 1st of this month. 

Cougar caught on DNR trail camera October 1, 2018

Since multiple sightings of the same animal have been verified, the total number of the massive cats may well be much less, but who really knows? 

The last image was found on a game camera installed by the DNR to study deer movement 9 miles north of Ironwood in Gogebic County.  “This latest confirmed report illustrates just how rare cougars are in the Upper Peninsula,” said Brian Roell, a DNR wildlife biologist in Marquette. “This is the first time we’ve ever caught a cougar on more than three million game camera images we’ve collected in our studies since 2009.”

They may be rare indeed, but nonetheless, knowing that these wild, carnivorous cats weighing as much as 200 pounds or more roam the wilderness in the land of Yoopers is a bit scary for this outdoorsman.  Oh, I can hear the odds makers on the chances of such an encounter, but I’d rather bet on my chances with a .44 magnum than playing dead – which by the way is a good way to end not only the game, but one’s life.

Human contact is still rare, but one account earlier this year in Washington State went against the odds.  A mountain lion, or cougar if you will, killed one mountain biker and mauled another in May, when they rode into its territory; authorities later shot the animal dead.

Family pets have also become prey, as was the case February 9, 2017 in Glendale, California.  Erinn Brown said everything seemed normal when she opened a door and let out her poodle outside.   “Then I saw that our dog was hanging limp from the top of the fence,” she said.  The mountain lion then jumped over the fence and departed.

According to the DNR, there remains no conclusive evidence of a Michigan breeding population of mountain lions.

Previous genetic testing on tissue samples from two cougars poached in the U.P. showed the two animals likely came from a population found generally in South Dakota, Wyoming and northwest Nebraska.

“This genetic research lines up with what we’ve presumed previously, that cougars found in the Upper Peninsula are males dispersing from this population east of the Rocky Mountains,” said Kevin Swanson, a DNR wildlife management specialist with the department’s Bear and Wolf Program. “These males dispersed from the main population are looking to establish new territories.”

Researchers investigated the potential population of origin for the two cougars using a database that includes samples from cougar populations in South Dakota, North Dakota, Nebraska, Montana, Wyoming, Colorado, New Mexico, Arizona, Texas, Oregon and Florida.  Cougars are an endangered species in Michigan protected by law.

At one time, cougars lived in every eastern state in a variety of habitats including coastal marshes, mountains and forests. They were native to Michigan, but were trapped and hunted from the state over 100 years ago.

Thirteen western states allow cougar hunting and the North American cougar is listed there as a game species.

J.R. Abser reports that one student-led project was directed by the University of Washington’s Laura Prugh and initiated as part of a community ecology class she taught in 2014 at the University of Alaska Fairbanks.  “The important take-home is that there can be very tangible benefits to having large carnivores around — economic and social benefits, not just ecological benefits,” said Prugh, a UW assistant professor of quantitative wildlife sciences in the School of Environmental and Forest Sciences.

The conclusion showed value in reducing deer-vehicle collisions as a case study, that within 30 years of the big cats recolonizing the Eastern U.S., the species could thin deer populations and reduce vehicle collisions by 22 percent — each year preventing five human fatalities, 680 injuries and avoiding costs of $50 million.

Could this be the answer to controlling our vehicle/deer collisions and Chronic Wasting Disease?  I sure hope not!

Michigan DNR game camera records cougar in Gogebic County

DNR game camera records cougar in Gogebic County

A second game camera image of a cougar in Gogebic County on Oct. 1.A game camera set up as part of an ongoing state deer movement study has captured images of a cougar in Gogebic County, about 9 miles north of Ironwood.

The images were reviewed and verified by the Michigan Department of Natural Resources’ cougar team.

Since 2008, the DNR has confirmed 38 cougar reports, with all but one of those occurring in the Upper Peninsula. These reports include multiple sightings of the same cougar, not 38 individual animals.

So far, there remains no conclusive evidence of a Michigan breeding population of mountain lions. Cougars are an endangered species in Michigan protected by law.

“This latest confirmed report illustrates just how rare cougars are in the Upper Peninsula,” said Brian Roell, a DNR wildlife biologist in Marquette. “This is the first time we’ve ever caught a cougar on more than three million game camera images we’ve collected in our studies since 2009.”

DNR researchers use game cameras in their Quantifying Upper Peninsula Deer Movements and Abundance, predator-prey and bear studies. The deer movement study alone uses 50 game cameras in the western U.P., including the one in Ironwood Township that caught the images of the cougar at 7:15 p.m. on Oct. 1.

A graph shows the number of confirmed Michigan cougar reports in recent years.The three daylight photos on the game camera show the mountain lion walking past, from right to left. Biologists noted there was no tracking collar on the cougar. No identification of whether the animal was a male or female was possible.

Michigan cougar confirmations have been derived from trail camera video, photographs, tracks, scat, or in the case of two male cats poached, carcasses.

Previous genetic testing on tissue samples from those two cougars poached in the U.P. showed the two animals likely came from a population found generally in South Dakota, Wyoming and northwest Nebraska.

“This genetic research lines up with what we’ve presumed previously, that cougars found in the Upper Peninsula are males dispersing from this population east of the Rocky Mountains,” said Kevin Swanson, a DNR wildlife management specialist with the department’s Bear and Wolf Program. “These males dispersed from the main population are looking to establish new territories.”
