Birds Obey Speed Limits

How Did the Animal Cross the Road? The Shocking AnswerCanadian researchers found that European birds flee before an approaching car at an interval that is consistent with the road’s speed limit, but not with the actual speed of the approaching car. So birds on a highway fled sooner than birds on local, residential roads. The researchers studied roads in three speed categories.

There are conservation implications for this finding, as an article in AAAS’s ScienceShot says.

The Nation’s Strangest Wildlife Laws

In Georgia, you may not keep a garter snake as a pet, but you can own a rattlesnake, says Whit Gibbons, an ecologist and environmental educator with the University of Georgia’s Savannah River Ecology Laboratory, in a column in the Aiken (Georgia) Standard.

The poisonous snake exception to Georgia’s law prohibiting the ownership of native snakes and reptiles is probably the weirdest law in Gibbons’ round-up, which includes the fact that frogs are regulated as fish in Alaska and that you may hunt frogs with a dog in Kansas. (Frogs, you know, are both funny and hard to legislate, so lots of frog laws make the list.)

I appreciate Gibbons’ list for its intelligence and wit, but I suspect that the regs he lists are not the nation’s weirdest wildlife laws. Does your state have a weird wildlife law? Do you know of one in another state? I’d love to hear about it in the comments.

Troublesome Creatures

spotted owlEfforts around the country to remove troublesome creatures — whether invasive or otherwise — have been met with a variety of reactions. In all cases the creatures are being removed because they are harming an ecosystem.

No one seems to mind that California Fish and Wildlife Department is removing South African clawed frogs from Golden Gate Park. The frogs are not native to the area, they completely destroy the habitats they invade, and they carry a fungus that is deadly to native amphibians. Read about the recovery effort in Bay Nature.

In Michigan, the Department of Natural Resources would like there to be fewer invasive mute swans. Mute swans are aggressive and don’t allow the native trumpeter swans or loons to nest. (They also have it in for ducks and geese.) Plus, they eat so many wetland plants that they can destroy wetlands. Oiling eggs has been too costly and too slow, so the department will begin to kill mute swans. Michigan Live has published several articles on the subject.
Here’s Michigan Live on why.
Here’s the plan in one county.
And here the reaction to the plan in that county.

And then there are barred owls. They’ve long been identified as a threat to northern spotted owl recovery in the Pacific Northwest. Spotted owls rely on old-growth forests. Barred owls are not so picky, and have moved into the spotted owls’ turf as the habitat has become more variable, because the old-growth forests were cut. The U.S. Fish and Wildlife Service has decided to start killing barred owls to try to improve matters for the spotted owl. The Oregonian did two stories on the situation. This one several years ago. And this one now that the program has begun.
There’s been no shortage of news coverage. See a lot of it here.

Burying Beetles and Goshawks Up

goshawk-259x300Here’s some good news for a Monday morning.

– Wildlife biologists with the Maryland Department of Natural Resources (DNR) have discovered Northern Goshawks successfully breeding in the State for the first time since 2006. Read the Maryland Department of Natural Resources press release, here.

– A second wild American burying beetle population now calls Nantucket, Massachusetts home, thanks to a successful captive breeding and reintroduction program, which began in 1996 at the Roger Williams Park Zoo in Providence, Rhode Island. Read this Endangered Species Act Success Story on the US Fish and Wildlife Service website, here. Lots of photos.

August Citizen Science Round-up

– The North Carolina Wildlife Resources Commission wants to document observations of nine-banded armadillos as they expand their range in the state. Read more in the Burlington Times-News.

– The New York State Department of Environmental Conservation (DEC) second annual Asian long-horned beetle (ALB) Swimming Pool Survey. Pool owners are asked to check their filters for the destructive, invasive beetles. Read the NYS DEC press release here. Vermont is in on the survey too. Read its program release here. The release implies that New Hampshire is also doing a pool survey.

Southwestern Naturalist Round-up

southwesternnaturalistcoverHere are some papers from the most recent issue of the Southwestern Naturalist that may be of interest to others outside the region, or of particular interest locally:

Fine-Scale Selection of Habitat by the Lesser Prairie-Chicken. Temperature turns out to be very important.

Consumption of Seeds of Southwestern White Pine by Black Bear. Black bears steal from squirrel caches. Go figure.

Is False Spike (a freshwater mussel) Extinct? First Account of a Very Recently Deceased Individual in Over Thirty Years. This species may still be in Texas.

Horsehair worm: New to the Fauna of Oklahoma. A second species of horsehair worm is discovered in the state.

New Distributional Records for Four Rare Species of Freshwater Mussels in Southwestern Louisiana. It’s not easy being a mussel. These are hanging on.

Critical Habitat Assessment Tool for Lesser Prairie Chickens

lesser prairie chickenFrom a press release issued by the Oklahoma Department of Wildlife Conservation and the Kansas Biological Survey:

In cooperation with the five state fish and wildlife agencies that fall within the range of the Lesser Prairie-Chicken (LEPC), and the Western Association of Fish and Wildlife Agencies (WAFWA), the KARS program has launched version 2.0 of the Southern Great Plains Crucial Habitat Assessment Tool (SGP CHAT). The online map viewer hosts the SGP CHAT, which is the spatial representation of the LEPC range-wide conservation plan, and a tool that prioritizes conservation actions while assisting with the siting of industry development.

August Research Round-up

NYS bobcat– Ohio Department of Natural Resources is studying how and why bobcats have returned to the state, by tracking 21 collared bobcats, The Madison Press reports. Previous research showed that there are two distinct populations of bobcats in the state. DNA analysis showed that the bobcats in both populations are from Pennsylvania, West Virginia and Kentucky. Read more in The Madison Press, here.

– David “Doc Quack” Riensche, an East Bay Regional Park District biologist, has been studying western pond turtles in in the eastern foothills of Mount Diablo outside Clayton, California for three years, the San Francisco Chronicle reports. The study has collected information on where the turtles winter and lay eggs. Western pond turtles are the only turtle native to California, but they face competition from non-native turtle species. Read more in the San Francisco Chronicle, here.

– Nearly 100 research volunteers surveyed the Cherokee Nation in Oklahoma for bats for this year’s “Bat Blitz,” organized by the Southeastern Bat Diversity Network, the Catoosa Times reports. One of the goals of the blitz is to document bat diversity before white nose syndrome harms bat populations in Oklahoma. Read more in the Catoosa Times.

White Nose Fungus in Minnesota

In a Friday afternoon press conference, the Minnesota Department of Natural Resources announced that it found the fungus that causes white nose syndrome in bats in a cave at Forestville/Mystery Cave State Park and at the mine at Soudan Underground Mine State Park.

No bats with white nose syndrome symptoms have yet been found, but the finding is devastating for several reasons. First, Minnesota’s winters are long enough and cold enough to expect that white nose syndrome symptoms will appear and kill bats. Second, according to the Duluth News-Tribune the two sites are the state’s largest wintering locations for bats. Third, Minnesota represents a significant leap from the areas where the fungus has already been found, and the finding may be a sign that that the fungus has spread to the Midwest.

Frogs and Pesticides

pacific tree frogTwo fungicides are showing up in the tissues of Pacific treefrogs, even those that live in pristine national parks, a recent paper in the journal Environmental Toxicology and Chemistry shows. The pesticides aren’t just coming from agricultural operations, but also from illegal marijuana farming.
Read the LiveScience article here.
Find the abstract for the paper here.

A study published in the journal Evolutionary Adaptations found that frogs collected from ponds where their ancestors were likely exposed to the pesticide chlorpyrifos showed greater tolerance to that pesticide themselves, perhaps showing an evolutionary adaptation to surviving exposure to that pesticide.
