Two new international agreements will help to save migratory birds from hunting, trapping and poisoning, and to protect their long-distance flyways. A key objective is to phase out lead shot within three years, and eliminate the toxic drug diclofenac.

Just as soldiers on sentry duty constantly adjust their behaviour to match the current threat level, dwarf mongoose sentinels exhibit flexible decision-making in relation to predation risk, new research from the University of Bristol has shown. 

Biologists Julie Kern and Dr Andy Radford found that decisions about when to go on duty, what position to adopt and how long to remain on post were all affected by information about the likelihood of danger. Sentinels altered their behaviour depending on both environmental conditions, such as wind speed and social signals, such as alarm calls.

If you care about saving the planet, then you really should be eating bugs. While the practice may not be widely accepted in the United States, Exo, a New York company with local connections that makes protein bars using cricket flour, wants to change that.

Exo, which is headquartered in Brooklyn, was founded in 2013 by two recent Brown University graduates, Greg Sewitz and Gabi Lewis. The two co-CEOs are hoping their line of products will normalize eating insects, which, in other parts of the world, are a common low-impact source of protein. In fact, insects contain more protein per 100 grams than dried beef, sirloin steak or chicken breast.

Thanks to the kindness of a caring citizen and the expertise of wildlife rehabilitators in Virginia, a common raven has been successfully returned to her home in the wild after being rescued and receiving months of care and a feather transplant.

The raven was first spotted by Maureen Bergin, an IT specialist at Anthem Blue Cross and Blue Shield earlier this spring in the parking lot where she worked in Henrico County with missing feathers that left her unable to fly.

Protected areas are undoubtedly the world's most important conservation success story, and recent research shows that protected areas are effective—housing more biodiversity and greater abundances of species inside rather than out. But, despite this, progress on protected areas is stalling and in some cases even falling behind. According to a sobering new paper today in Nature, only 20-50 percent of the world's land and marine protected areas are meeting their goals, while the rest are hampered by lack of funding, poor management, and government ambivalence. The paper arrives just a few days before the opening of the IUCN World Parks Congress 2014, a global event that happens once a decade. "Protected areas offer us solutions to some of today's most pressing challenges, but by continuing with 'business as usual,' we are setting them up for failure," said lead author James Watson of the Wildlife Conservation Society and the University of Queensland. "A step-change in the way we value, fund, govern and manage those areas is neither impossible nor unrealistic and would only represent a fraction of what the world spends annually on defense." 

As the International Commission for the Conservation of Atlantic Tunas (ICCAT) opens its 19th special meeting in Genoa, Italy on Monday 10 November, WWF calls on delegates to stay cautious regarding the management of Mediterranean bluefin tuna. Despite recent indications that the stock is recovering, substantial shortcomings still undermine traceability of the fishery, allowing for illegal, unreported and unregulated (IUU) bluefin tuna to reach global markets.

Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, according to the findings of a new study. However, the research conducted by the University of Exeter, the RSPB and the Pan-European Common Bird Monitoring Scheme (PECBMS), found numbers of some less common birds have risen.

A majority of recent reports highlights the negative effects of warmer water temperatures on corals. Because of increasing numbers of bleaching events, where corals become white resulting from a loss of their symbiotic algae, corals become stressed and can starve to death if the condition is prolonged. However, researchers from Northeastern University's Marine Science Center and the University of Chapel Hill have found some slightly positive effects that moderate ocean acidification and warming can have on coral.

A group of scientists working in collaboration with a filmmaker have come up with a clever, and adorable, way to study notoriously shy Emperor penguins in Adélie Land, Antarctica by sending in a rover disguised as a chick that was so convincing penguins tried to make conversation with it. As researchers explain in a study published in the journal Nature Methods, which was led by Yvon Le Maho of the University of Strasbourg in France, scientists have been unable to study these penguins up close without seriously stressing them out, altering their behavior or causing them to retreat.

Several recent sightings of what’s believed to be a gray wolf at the Grand Canyon in Arizona have wolf advocates hopeful that its presence, which marks the first time one has been seen in the state in 70 years, is yet another a sign of recovery for this iconic species. The lone wolf in question was first spotted in early October by visitors at the Kaibab National Forest north of the Grand Canyon National Park and described as a wolf-like animal, but photos made public by the Center for Biological Diversity – in an attempt to ensure it wasn’t mistaken for a coyote and killed – have led wildlife and park officials to believe it’s a gray wolf.
