It's been 20 years since the last Spix's Macaw has been seen in the wild, but the near-extinct species could be set to make a comeback. In a few days, the bird will be reinstated in a reserve, located in Caatinga in northeastern Brazil, thanks to a breeding and rehabilitation program.

Extinction, a new book by Marc Schlossman, explores endangered and extinct species and the factors threatening them through a rare behind the scenes look at one of the most important sets of natural history collections in the world at the Field Museum in Chicago.

Billions of birds are disappearing because of humanity’s impact on Earth, global review finds

Seals are the “rats of the sea” and should be culled, a group of Cornish fishers have said. Marine campaign groups hit back after fishers on an online marketplace and forum expressed anger about the amount of fish seals eat.

Tar Creek doesn’t seem like an inviting home for wildlife. For more than 70 years, miners blasted open the earth underneath the Oklahoma waterway in search of lead and zinc. Today, mountains of waste material from the mines tower above what is now classified by the EPA as a Superfund site. Groundwater that flows through the abandoned mines flushes toxic heavy metals, including cadmium and lead—both potent neurotoxins even at low concentrations—into the creek. The water runs bright orange.

In response to three lawsuits brought by the Center for Biological Diversity, the U.S. Fish and Wildlife Service agreed today to dates for decisions on whether 18 plants and animals from across the country warrant protection as endangered or threatened species under the Endangered Species Act. The Service will also consider identifying and protecting critical habitat for another nine species.

Jaguars are the only species of big cat found on the American continent. They range as far south as Argentina, and once roamed as far north as the Grand Canyon in the U.S. Today the northernmost breeding population is in the northwest Mexican state of Sonora, just south of the border with Arizona.

A wind energy company was sentenced to probation and ordered to pay more than $8 million in fines and restitution after at least 150 eagles were killed over the past decade at its wind farms in eight states, federal prosecutors said Wednesday.

America’s national bird is more beleaguered than previously believed, with nearly half of bald eagles tested across the US showing signs of chronic lead exposure, according to a study published Thursday.

Retired salesman John Stimpson is 80 today. He will be celebrating with a cake at Slimming World this evening, followed by dinner with his family on Friday. Stimpson has one achievement in particular to mark: he has just completed his goal of building 30,000 swift boxes, which could house half of the UK’s breeding population of 60,000 pairs.

A total of 1,070 occupied bald eagle nests were counted in this year's survey by the Center for Conservation Biology at the College of William and Mary. It's the first time more than 1,000 have been counted since the survey started 60 years ago. This marks a remarkable comeback for the bird whose population had dropped to just 20 pairs in the state in 1970, said Bryan D. Watts, the center's director.

Officials have agreed to allow as many as 900 bison from Yellowstone National Park to be shot by hunters, sent to slaughter or placed in quarantine this winter in a program that seeks to prevent the animals from spreading a disease to cattle. An additional 200 bison among the park’s more than 5,000 bison could be captured or hunted in the late winter if those numbers are met, federal, tribal and state officials agreed in a meeting Wednesday.

Climate change is forcing some animals to move. Don’t call them "invasives."
