Antarctic krill — tiny, filter-feeding crustaceans that live in the Southern Ocean — have long existed in mind-boggling numbers. A 2009 study estimated that the species has a biomass of…
Despite some amazing rebounds, six decades after Rachel Carson’s call to curb pesticide use, the world’s birds are in deep trouble — assaulted by toxic chemicals, lost habitat, hunting, invasive species, and climate change.
Tim Beatley will humbly tell you that he’s not a birder. But in his new book, there are enough appearances by obscure members of the class Aves to suggest that…
BUNDALA, Sri Lanka – The glossy ibis (Plegadis falcinellus) is a fairly rare but regular winter visitor to Sri Lanka, seen at the Bundala National Park in the island’s south…
It was one of the worst environmental disasters the world has witnessed. Ten years ago, on April 20, 2010, the BP Deepwater Horizon exploratory rig exploded, killing 11 people and…
Scientists and conservationists have long expressed concern about the consumption of bushmeat, mindful of its impact on wildlife and human health. Yet the marine equivalent has received relatively little attention,…
The camera traps that ecologist Annette Fayet had set up didn’t provide the clues she had hoped to find about puffin diets and nesting behavior. What they did provide, though,…
For seabirds, an Arctic Ocean with less sea ice could provide some tantalizing alternatives to the long-haul flights that some undertake each year. In a recent study, ecologist Manon Clairbaux…
In a classic poem, an ancient mariner finds himself haunted by the albatross he killed. Two hundred years after Samuel Coleridge penned that poem, albatrosses still follow fishing ships. But…
The trade of live birds in South America is down to its lowest levels in years, according to a report released Jan. 16 by conservation NGOs TRAFFIC and WWF. But…
Competition for fish stocks with fisheries to feed humans could be forcing seabirds to go hungry, according to new research. The study, published Dec. 6 in the journal Current Biology,…
Data from GPS-tagged seabirds, as they were swept along in the strong currents of the Irish Sea, could help researchers move a step closer to harnessing the energy in those…
Plant numbers have surged in a group of islands in the Pacific Ocean following the eradication of invasive rats that gobbled up seeds and gnawed away at vegetation, a new…
TOULOUSE, France -- Rats exact a punishing toll on island seabird colonies, decimating their numbers as they eat the birds’ eggs and young. Research has shown that fewer birds, and…
Lighten up We’ve all seen insects fly toward light. Moths, for example, use moonlight to stay upright, fly straight, and remain oriented at night. Other groups of animals, including various…
New research finds that increased sea surface temperatures can affect the survival of juvenile albatross during their first year at sea and lead to reduced population growth rates. Ecologists with…
On today’s episode: the sounds of Buller’s shearwaters in New Zealand’s Poor Knights Islands. Listen here: Our guest today is Megan Friesen, a behavioral ecologist who is currently working with…
Jarrod Hodgson is one of very few scientists who have used rubber ducks as part of their Ph.D. research. Hodgson and colleagues at the University of Adelaide compared the accuracy…
Study: rapidly warming Arctic reduces food supply and stored energy for shorebird, weakening juveniles on long migratory trips, reducing size, survival chances.
In a search to locate the nesting grounds of the ringed storm-petrel (Oceanodroma hornbyi) a team of Chilean biologists didn’t rely on high-tech tracking devices or aerial mapping tools. Instead…
Evolution can be an exquisite hammer, tapping out finely honed strategies for the survival of life on Earth against the blunt force of the environment. But mess with those surroundings too…
Since seabirds rely on healthy oceans to feed and thrive, scientists consider them excellent indicators of the marine ecosystem's health. But a recent study found that global seabird populations appear…
Tufted puffins in the Alaska Maritime National Wildlife Refuge. The species is commonly caught in driftnet salmon fishing gear in the waters off Russia's far eastern shore. Photo credit: Steve…
Seabirds, aerial ocean predators, are known to amass harmful contaminants over their lifespan. Scientists believe this exposure to pollutants, such as blood mercury (Hg), cadmium (Cd), and persistent organic pollutants…
In the last 500 years, the oceans have suffered far fewer extinctions than on land—at least that we know of. According to a recent study in Science, 15 animals are…
Although only a nuisance in your home, on an isolated island chain (archipelago) off the northeastern coast of Brazil, rats pose a threat to the red-billed tropicbird (Phaethon aethereus).…
Joanna Alfaro Shigueto will be speaking at the Wildlife Conservation Network Expo in San Francisco on October 11th, 2014. Marine conservationists often view fisheries as an enemy of sorts, vacuuming…
Aside from reducing the populations of the species sought for capture, commercial fisheries are also killing thousands of non-target creatures such as sharks, albatross, and sea turtles, collectively referred to…
The number of threatened species on the IUCN Red List has grown by 352 since this summer, according to an update released today. Currently, 21,286 species are now listed as…
A recent study from the Biological Conservation journal brings shocking news: every year across the globe, an estimated 400,000 seabirds are killed by gillnets. Gillnets, a common term for any…
