Endangered Species

Bald Eagle Spotting: Top Spots

Dec 27, 2013 12:43 PM ET // by Tim Wall

Forty years ago, the Endangered Species Act was signed into law by President Richard Nixon. The act’s authors sought to protect animals, plants and other wildlife from extinction caused by “economic growth and development untempered by adequate concern and conservation,” in the words of the Act.

One symbol of the United States, the bald eagle, provides an example of how a change to the economy saved an icon of North America.

DDT, or dichloro-diphenyl-trichloroethane, weakened eagle and other bird egg shells so much that the eggs would collapse under the mother. The chemical was introduced in the 1940s and already had decimated bird populations by the early 1960s.

In 1972, the U.S. Environmental Protection Agency banned the pesticide. The removal of DDT from the market allowed eagle eggs to regain their strength, and the raptors began a recovery.

Bald eagles soared off of the Endangered Species List in 2007. Although off the list, the birds are still protected by the Bald and Golden Eagle Protection Act, Migratory Bird Treaty Act and the Lacey Act, according to the U.S. Fish and Wildlife Service.

LIST: Animals Back From the Brink

An eagle-watching trip could be a thrilling way to celebrate the 40th anniversary of the Endangered Species Act and the success of bald eagles.

From coast to coast, National Wildlife Refuges offer winter-long opportunities to observe the raptors, along with special events.

The USFWS presents a cross-country list of these eagle adventures in Maryland, Virginia, Illinois, Tennessee, Missouri, Oklahoma, Utah, California, Oregon and Washington. Here are a few highlights:

Maryland: Blackwater National Wildlife Refuge Eagle Festival March 15, 2014, from 9 a.m. to 4 p.m. The festival is a free way to see more than 200 eagles overwintering in the refuge, the largest population on the East Coast, north of Florida.

Illinois: Crab Orchard National Wildlife Refuge Eagle Watch Jan. 18-19, 25-26 at  8 a.m., 11 a.m. and 2 p.m. Reservations are required for this guided van trip to see eagle nests.

Missouri: Squaw Creek National Wildlife Refuge Open all winter. A 1.5-mile trail offers views of hundreds of eagles.

Oregon: Winter Wings Festival in Klamath Falls Feb. 13-16. Sessions on bald eagles and other raptors are featured events at this avian extravaganza.

The Endangered Species Act has prevented the extinction of 99% of the more than 2,140 species it currently protects: here.

Global Warming Beneficial to Ratsnakes

Jan. 8, 2013 — Speculation about how animals will respond to climate change due to global warming led University of Illinois researcher Patrick Weatherhead and his students to conduct a study of ratsnakes at three different latitudesOntario, Illinois, and Texas. His findings suggest that ratsnakes will be able to adapt to the higher temperatures by becoming more active at night.

Street coyotes more faithful than people, study suggests

Sept. 25, 2012

Coy­otes liv­ing in ur­ban areas nev­er stray from their mates—they stay to­geth­er till death do them part, ac­cord­ing to a new stu­dy.

Sci­en­tists say the find­ing sheds light on why the North Amer­i­can cous­in of the dog and wolf, which is orig­i­nally na­tive to deserts and plains, is thriv­ing to­day in metro­pol­is­es.

Re­search­ers with Ohio State Uni­vers­ity who ge­net­ic­ally sam­pled 236 coy­otes in the Chi­ca­go ar­ea over a six-year pe­ri­od found no ev­i­dence of polygamy—of the an­i­mals hav­ing more than one mate—nor of one mate ev­er leav­ing an­oth­er while the oth­er was still alive.

That was true, the sci­ent­ists said, even though the coy­otes live in dense­ly packed pop­ula­t­ions with plen­t­iful of food, con­di­tions that of­ten lead some oth­er mem­bers of the dog family to stray from their nor­mal mo­nog­a­my.

“I was sur­prised we did­n’t find any cheat­ing,” said study co-au­thor Stan Gehrt, a wild­life ecol­o­gist at Ohio State. “Even with all the op­por­tun­i­ties for the coy­otes to phi­lan­der, they really don’t.

“In con­trast to stud­ies of oth­er pre­sumably mo­nog­a­mous spe­cies that were lat­er found to be cheat­ing, such as arc­tic fox­es and moun­tain blue­birds, we found in­cred­i­ble loy­al­ty to part­ners in the study popula­t­ion,” he added.

The re­search ap­pears in a re­cent is­sue of The Jour­nal of Mam­mal­o­gy.

Coy­otes’ loy­al­ty may be a key to their suc­cess in ur­ban ar­eas, Gehrt said. Not only is a fe­male coy­ote nat­u­rally ca­pa­ble of pro­duc­ing large lit­ters of young dur­ing times of plen­ty, such as when liv­ing in food-rich ­ci­ties, she has a faith­ful part­ner to help raise them all. “If the fe­male were to try to raise those large lit­ters by her­self, she would­n’t be able to do it,” said Gehrt. “But the male spends just as much time help­ing to raise those pups as the fe­male does.”

Smaller treefrogs are more likely to “cheat” their way to a mate, French scientists have found. The team studied the response of differently sized European treefrogs to a chorus of mating calls: here.
