Kirtland’s Warbler Numbers Up in Michigan

Posted on October 24, 2012 by MadelineBodin

This year, researchers and volunteers in Michigan observed 2,063 singing Kirtland’s warbler males, up from 1,805 last year and the biggest single-year increase in the birds since 2007, the Michigan Department of Natural Resources reports.

These are the highest numbers ever for Kirtland’s warbler, a federally endangered bird, the release states. The warbler is endangered by habitat loss. It nests only in young jack pines, a habitat that only naturally occurs after periodic wild fires. Today the habitat is created through both prescribed burns and timber harvests with seeding. The birds range has expanded from Michigan’s lower peninsula, to its upper peninsula and into Wisconsin and Canada.

“We are witnessing a conservation success story,” said Michigan DNR endangered species coordinator Dan Kennedy in the release.

In other songbird news:

While bark beetle outbreaks have been bad news for many throughout the West, they have been good news for mountain chickadees, at least at a local level for short periods around the time of the outbreak, says an article in the journal Ibis.

Because the birds are secondary cavity nesters, the study notes, the number of mountain chickadees in a location in a particular year ties most closely to the number of downy woodpeckers and red-breasted nuthatches the previous year.

Colorado’s Urban Bears, Interim Report

Posted on October 23, 2012 by MadelineBodin

Colorado Parks and Wildlife (CPW) biologist Heather Johnson recently gave an interim report on her five-year black bear study to the state Parks and Wildlife Commission, the Durango Herald reports.

According to the CPW website, the study is intended to gather more information about the increase in conflicts between black bears and humans in the state. Does the increase reflect black bear population trends, or a change in behavior? To that end, the website says, the study:

1) tests management strategies for reducing bear-human conflicts, including a large-scale treatment/control urban-food-removal experiment; 2) determines the consequences of bear use of urban environments on regional bear population dynamics; 3) develops population and habitat models to support the sustainable monitoring and management of bears in Colorado; and 4) examines human attitudes and perceptions related bear-human conflicts and management practices.

One and a half years in, Johnson has found that female black bear behavior of the 51 collared bears she tracks is highly variable. One collared female never left a three block area in Durango, another wandered for 200 miles.

Up next is an experiment comparing conflicts in an area with bear-proof trash cans to one without the cans. That experiment will begin in the spring.

Smoothing Ruffled Feathers

Posted on October 19, 2012 by MadelineBodin

It took a long time to sort out, but this week the the federal Justice Department clarified its stand on native people possessing eagle feathers. The policy said that tribal members can possesses or wear feathers from bald or golden eagles. They can also lend, give or trade the feathers or bird parts to other tribal members, as long as money doesn’t change hands.

Further, tribal members can keep eagle feathers that they pick up off the ground, but they can’t kill or harass the federally protected birds to get the feathers. There’s a federal depository for eagles that were accidentally killed, and tribal members can apply to receive feathers or parts from the repository for ceremonial purposes.

The US Fish and Wildlife department also issues a few permits for tribal members to kill eagles for religious purposes.

The Summit County Citizens Voice was the article getting all the buzz. Read the article, here.
You can also check out the Washington Post‘s take on the issue, here.

But now that we have eagle situation solved, other migratory birds are an issue. An Alaskan man was stunned to find out that selling items decorated with bird feathers is illegal, the Anchorage Daily News reports. As a member of the Tlingit nation, he felt that he was just doing what his people had done for generations. He settled the case for a $2,005 fine.

Unfortunately, the article does not clarify how the federal Migratory Bird Act applies to tribal members, but it is likely that the rule is similar to the rule for eagle feathers and parts.

Wildlife Rehabilitators Decline

Posted on October 18, 2012 by MadelineBodin

Newspapers all over the country picked up this Associated Press article about the decline of wildlife rehabilitators in Wisconsin. The story says that half as many people are licensed as wildlife rehabilitators as were 12 years ago. In 2001 there were 225 organizations licensed and today there are 113.

The AP story did not dig deeper, but an article in the Press of Atlantic City that reported a similar trend in New Jersey back in February, did. It found that rehabilitator numbers are down in Florida and California as well.

Not having enough wildlife rehabilitators puts a strain on police, who must respond to distressed animal calls instead of a trained rehabilitator, and is, in general, a public relations black eye for state wildlife departments, who often must kill ill or injured animals when rehabilitation is not an option.

In New Jersey, a Wildlife Rehabilitator’s Act aims to increase the number of rehabilitators in the state by reducing red tape (by creating a licensing committee that is “in but not of” the state wildlife department) and changing the training requirements for rehabilitators. But the various bills put forward in the state senate and assembly have been controversial.

The NJ Division of Fish and Wildlife has created a wildlife rehabilitators advisory committee in attempt to get things on the right track. You can read agendas and minutes for the committee here.

Here are some articles of interest in the current issue of American Midland Naturalist. (Fee or subscription required to read the full text.):

The Impact of Exotic Purple Loosestrife (Lythrum salicaria) on Wetland Bird Abundances. Some wetland bird species do well when loosestrife increases, this study found. It urges land managers to take care when removing loosestrife so as not to harm those species.

Use of Camera Traps to Examine the Mesopredator Release Hypothesis in a Fragmented Midwestern Landscape. Coyotes don’t like deep forests and red foxes don’t like urban landscapes, this study found. The presence of coyotes only scared off other mesopredators a little.

Lots more on invasive species. Including papers on garlic mustard and the types of plants that grow in contaminated roadside soil.

Deer Health

Posted on October 16, 2012 by MadelineBodin

The Pennsylvania Department of Agriculture announced the first case of Chronic Wasting Disease (CWD) in deer there last week. As you may guess from the state department issuing the news, CWD was found in captive deer.

CWD had been found in New York, which borders Pennsylvania, several years ago and is believed to be eradicated there. But there have been more recent incidents in West Virginia and Maryland, which also border the state.

(My rough measurements show the Pennsylvania case as being about 40 miles from where CWD was found in Maryland and West Virginia.)

In other deer health news, Louisiana State Wildlife Division chief Kenny Ribbeck told the Louisiana Wildlife and Fisheries Commission last week that Hurricane Isaac killed up to 90 percent of the deer fawns in the Maurepas Basin, according to an Associated Press article that you can read in The Oregonian. Deer hunting in the region has been adjusted as a result.

And in the category of “when is no news actually news” the Canadian Cooperative Wildlife Health Centre notes in its blog that epizootic hemorrhagic disease (EHD) came awfully close to Canada this year. The midge that spreads EHD is not found in Canada, it says, but the disease may move north with the midge because of climate change. It also notes that because the disease has never struck there, the outbreak may be severe.

Penn. Abandons Bat Petition

Posted on October 12, 2012 by MadelineBodin

The article in the Pittsburgh Post Gazette seemed a little harsh, claiming that the Pennsylvania Game Commission caved to industry pressure when it abandoned its petition to list bat species that had been affected by white nose syndrome. A tiny bit of digging turned up the PGC press release, which pretty much admits to just that:

“Through this process, we heard from various wildlife organizations and representatives from the timber, oil, coal and gas industries, as well as legislators. At the present time, it is clear that more discussion, research and coordination need to be done on WNS and the other outside factors that are impacting our bat populations, as well as how we can craft solutions that protect bats without threatening the industries that employ thousands of Pennsylvanians.”

Game Checkpoints Provide Data on Human Diseases

Posted on October 11, 2012 by MadelineBodin

Hunter check-ins have always provided a bounty of information on the health of individual animals and the population profile of the species. In Maine this year and for the last few years, they are providing more. The Maine Department of Inland Fisheries and Wildlife has teamed up with the Maine Medical Center Research Institute’s Vector Borne Disease Lab to provide blood samples from moose, white-tailed deer and even some turkeys for the lab’s surveillance mosquito-borne diseases like West Nile and Eastern Equine Encephalitis, according to a story from WSCH TV in Portland, Maine.

By using blood samples from hunter check-ins, the lab is able to get information from remote areas that are difficult (and expensive) to monitor through traditional methods. And, according to the WSCH story, they are finding a surprising amount of these diseases out there.

Old-timers Keep Mountain Lions Stable

Posted on October 10, 2012 by MadelineBodin

In January, the Washington Department of Fish and Wildlife will begin using “equilibrium management” to determine the number of mountain lions (or cougars, Puma concolor) taken by hunters in each management unit, according to a press release from Washington State University. This will limit the take to the natural amount of reproduction — 14 percent, according to the release.

Research by Washington State University’s Large Carnivore Conservation Lab has found that mature, adult male mountain lions are the lynchpin of the species’ population dynamics. According to the press release, mature males will kill younger males to protect their territories, keeping the overall population low. The mature males are also less likely to prey on livestock.

There is no word, however, on how using equilibrium management will prevent hunters from killing all the mature males in an area, therefore releasing the less stable younger males.

Several news outlets have published the press release with no additional reporting. Read the press release here.

Vermont Eagle Population Soars

Posted on October 8, 2012 by MadelineBodin

Vermont has long lagged behind the other New England states in bald eagle populations. Even when bald eagle populations in neighboring states recovered to the point where they had dozens of nesting pairs, Vermont was still not home to eagles that were successfully raising young.

That changed in 2008, when a single pair fledged a single chick. In 2009, the state did its best to help a second breeding eagle pair that lost their nest when the tree it was in fell down. Now, just four years after that first eagle fledged, 23 eagles were fledged in 15 Vermont nests this year, reports the Vermont Department of Fish and Wildlife.
