In PNG, researchers find a large pigeon lost to science for 140 years
After 140 years, a pigeon subspecies lost to science has been found again on Fergusson Island off eastern Papua New Guinea. Using a remote camera trap, researchers photographed the black-naped pheasant-pigeon (Otidiphaps nobilis insularis), a large, ground-dwelling bird, for the first time since it was described in 1883. “After a month of searching, seeing those […]
Mercury rising: Why Bolivia remains South America’s hub for the toxic trade
LA PAZ — Mercury, even at room temperature, will slowly transition from its silver liquid state into a dangerous vapor that, when inhaled, can leave a person with permanent brain and lung damage. It also happens to be extremely useful for separating gold from other particles, like dirt, making it a popular tool for many […]
Beef is still coming from protected areas in the Amazon, study shows
Some of the world’s largest beef exporters are still buying cattle that grazed in protected areas of the Amazon rainforest, despite commitments to stop this practice, according to a new study.

Heat-sensing drone cameras spy threats to sea turtle nests
Sea turtles lumber from ocean to shore to lay their eggs in the sand. In some places, this effort is protected by humans who patrol beaches on foot, warding off poachers, predators and naïve tourists. But might there be a more effective way? Researchers used thermal infrared sensors mounted on drones to monitor sea turtle […]
Toxic new frog species from Ecuador named after Family Guy’s Seth MacFarlane

The mystery of narwhal behavior, solved by chaos theory
Narwhals are chaotic. At least, that’s what researchers thought until they developed a new math-based method to detect patterns in their seemingly irregular movements. Narwhals (Monodon monoceros) are known as the unicorns of the sea due to their distinctive single tusk, which is actually a feeling, enlarged tooth with up to 10 million nerve endings. […]
Tiny new tree frog species found in rewilded Costa Rican nature reserve

Seeing through the swarm: How hawks hunt bat prey
Raptors are famous for their ability to home in on prey and attack with precision. But how does this work when they hunt animals that flock, school or swarm, forming bewildering displays that appear to move everywhere all at once? A study published today in Nature Communications reports that Swainson’s hawks (Buteo swainsoni) and some other raptors […]
