Plague: Human Cases in NM, Squirrel Case in Cal.

New Mexico has had all three cases of plague in humans that have occurred in the United States this year, a New Mexico Department of Health press release reports.

Read the press release here. (Will open a PDF.)

The bacteria that causes plague is endemic in the southwestern US. Wildlife cases are so common that I don’t report them here, but those cases can be an important warning to locals to take extra care to keep their pets away from wildlife and to avoid flea bites, and for wildlife managers and researchers to take precautions as well.

Just such a warning is in place in Palomar, California, where ground squirrels at a campground have been diagnosed with plague.

Wildlife and Infrastructure

terrapincrossingSure, you know all about roads and wildlife, but roads are not the only place that wildlife and human infrastructure can do bad things to each other. Two recent stories point out some of the more unusual ways that wildlife influences modern life, and how our modern structures influence the survival of wildlife. (Although that sounds so serious. One of these stories is “cute,” and the other has been mostly reported as “cute.”)

New York City’s Kennedy Airport is on the shores of Jamaica Bay, which is an estuary off the Atlantic Ocean. In addition to the airport, the bay is also home to the National Park  Service’s Jamaica Bay Wildlife Refuge. This creates all sorts of interesting interactions between airplanes and wildlife, but the story of the last two years has been that diamond terrapins, an aquatic turtle, have been crawling across the airport’s runways in search of nesting sites.

Read the whole story in the US Fish and Wildlife Service’s Northeastern Region blog, here.

New York Times Magazine contributor Jon Mooallem has been tracking P.O.C.B.S. — power outages caused by squirrels. He writes about it in the New York Times opinion section. There are many serious potential take-aways in this humorous story, one of which is that no one really knows how many power outages each year are caused by squirrels, or other wildlife.

Study of California Gray Squirrels

At first they were, like gray squirrels almost everywhere in the US, abundant to the point of being a nuisance, especially to people with bird feeders. Then they were gone, or almost so. When mange struck the gray squirrels of the San Bernardino Mountains in California, people noticed, particularly in the past year.

While the cause is known, a new study by the University of California, Davis School of Veterinary Medicine, California Fish and Game Wildlife Investigations Lab and California Animal Health and Food Safety Lab will delve into when and how of the population crash.

The study will rely heavily on reports from citizens in the area.

Winter Research Roundup

In New York State, a recent survey of the spruce grouse population revealed that there are not many of the birds left in that state. A revised management plan seeks to restore the population.

New York State has also released a management plan for bobcats. The plan includes a survey of the state’s current bobcat population. Comments on the plan are being accepted until February 16.
Read an article about the plan in North Country News, here.
Here’s the state’s bobcat page, with a link to the management plan.

In California, the Department of Fish and Game is looking for volunteers over 16 years old and in good health to help count bighorn sheep in the San Gabriel Mountains on March 4. There is an orientation on March 3.

Also in California, the US Fish and Wildlife Service will review the status of the San Bernardino flying squirrel. It’s soliciting information about the flying squirrel and its habitat from state and federal natural resource agencies until April 2.

Google Maps for Cit Sci Apps

The Florida Fish and Wildlife Conservation Commission is using a Google Maps application to gather basic information about the locations of fox squirrels in that state. Fox squirrel distribution is patchy, and there hasn’t been a distribution survey since 1997.

See the form here.

University of Florida wildlife ecology graduate student Courtney Hooker, who is overseeing the survey, was inspired by another Google Maps application that she had used herself: The South Carolina-based Center for Birds of Prey’s swallow-tailed kite project.

See that form here.

Hooker says the fox squirrel application has worked well since going on line in August 2011. “Most people are familiar with Google Maps, since they use it to get directions,” she says. The project has received over 600 reports so far, and has received a lot of media coverage.

Although the directions for logging a fox squirrel sighting on the site is only three short steps, Hooker says that she may make them even shorter and simpler. Many people aren’t reading them. Also, she prefers the way the swallow-tailed kite map allows users to right-click on the location they saw the bird. The fox squirrel map asks users to drag a red balloon to the site, which is a little confusing. 

Hooker says that part of the success of the project is due to the fact that the fox squirrel, which is twice the size of the familiar gray squirrel, is such a striking species. “It’s an identifiable species and it’s a beautiful species. People tend to remember it.”

One of the few questions on the sighting form ask if the observer is a wildlife professional or not. Hooker was curious to see if a particular group was more responsive to the survey. So far, she says, about 95 percent of the respondents have been citizen scientists.

Many of the reports have been acommpanied by photos, she says, so Hooker has been able to confirm that they are indeed fox squirrels and not another species.

Hooker says that while the project is expected to help state biologists better understand the distribution of the fox squirrel throughout Florida, it’s also helped educate the public. “Some people have said that they had never seen one before.”

Squirrels, snails captive bred in Arizona

File under “food for thought”: according to an article in the New York Times, four Mount Graham red squirrels and hundreds of Three Forks springsnails are being raised in captivity at the Arizona Zoo. For the squirrels, the reason is a worse than average fire season has increased the threat to the rare squirrel.

The Mount Graham red squirrel was once thought to be extinct. It was placed on the federal Endangered Species list in 1987. It has been controversial because it once held up the construction of the Mount Graham International Observatory in one of those somewhat rare and always fascinating big science vs. wildlife conservation showdowns.

The Times article includes a link to further species info on the squirrel.

Mites Hammer Western Gray Squirrels

Western gray squirrel populations have been declining throughout their range. Recently the California Department of Fish and Game confirmed that the gray squirrel decline in the San Bernardino mountains is being caused by a mange mite, thought to be Notoedres centrifera.

The good news for local residents is that the mite effects only rodents, so dogs and other pets should be safe. The bad news is that the free lunch for squirrels at backyard bird feeders is contributing to the problem, allowing the mite to spread when squirrels gather for a backyard buffet.

The Riverside Press-Enterprise has the news story.

The press release from California Fish and Game has more detail, plus a discussion of other possible causes of the squirrel’s decline.

In other squirrel news, and yes, there is other squirrel news, the squirrel pox that has been killing off native red squirrels in Britain has arrived in Northern Ireland. Squirrel pox was introduced to the region along with North American gray squirrels. The gray squirrels are carriers, and don’t show symptoms. Find the BBC story here.

How did the flying squirrel cross the road?

Photo: NC Wildlife Commission

Endangered Carolina northern flying squirrels can now safely cross the Cherohala Skyway in western North Carolina thanks to telephone-pole-like crossing structures. Before the poles were installed, in 2008, the squirrels did not cross the Skyway because the distance between the trees on either side of the road exceeded their gliding ability. The northern flying squirrel populations on each side of the roadway did not interbreed.

The squirrels’ use of the poles has been documented with video cameras mounted on the pole tops.

The North Carolina Wildlife Resources Commission hopes to allow trees to grow closer to the Skyway, which will allow them to eventually remove the poles.

More details, and a video, are available from the Commission’s press release.
