Audubon's recent "BirdNote" podcast explains the peculiar head movements of owls. No, it's not just to creep out humans. There's a good reason for all that staring, twisting and bobbing.
A recent study on Eurasian Siskins proves that smaller birds prefer to travel in groups like their larger counterparts, swans, geese and crows.
Researchers have documented how leafcutter ants process leaves into nutrients underground. The remarkable nimble ants rely on a division of labor to get food on the table and conserve energy, thus ensuring they remain healthy and strong – the better to suit the colony.
Massachusetts' State Department of Fisheries and Wildlife has proposed breeding 150 venomous timber rattlesnakes on a remote island to save the endangered species. What could possibly go wrong?
A recent study on Border Collies confirms older dog can be taught new tricks, although younger individuals learn faster.
Bedbugs are hardy pests that have built up a strong resistance to common pesticides. In a recent study, researchers sequenced the genome of these bugs, revealing unique genetic features that could help create better methods of pest control.
A new study suggests nurse sharks have the lowest metabolic rate of any shark species. This means they don't have as great an impact on their ecosystems as large predators do.
A new study from McMaster University challenged Charles Darwin's long-standing theory of female choice. Rather than females being drawn to males that have the most vibrant tail feathers or best dance moves, researchers suggest that, once aroused, courtship displays have no bearing on a female's mate preference.
Burned and cracked tortoise shells found inside Qesem Cave near Tel Aviv, Israel, suggest early hunter gatherers enjoyed snacking on roasted tortoise shells. However, researchers say the tortoises would have only been a side dish, as they would not have provided enough calories.
A critically endangered population of killer whales in the Pacific Northwest may be encountering more noise pollution than in the past. A recent study suggests large passing oil tankers emit sounds at frequencies killer whales use to communicate and echolocate. Ultimately, researchers say, this could impede their ability to find food they need to survive.
Reed warblers have set up a "neighborhood watch" to protect their nests from invasive cuckoos, who lay their eggs in local nests for others to raise. When reed warblers spot a cuckoo, they mob it and emit alarm calls that alert neighbors a cuckoo is at large and they should monitor their eggs closely. This has greatly benefited warblers, but cuckoo populations appear to be suffering.
Two new unique species of tree frogs were recently found in broadleaf forests in the island country of Taiwan. Researchers say each is adorned with gemstone-colored eyes.
Yellowstone National Park is expected to kill nearly 900 of its bison this winter, marking the largest cull since 2008. Although laws state that culls are needed to manage growing populations and protect Montana's livestock for infectious diseases bison may be carrying, conservationists argue this large-scale slaughter is unnecessary and brutal -- they have filed a lawsuit claiming that the public has a right to witness this year's controversial cull.
Biologists have genetically engineered mosquitoes to reduce populations of mosquitoes carrying Zika virus, which is linked to a birth defect known as microencephaly. The hope is this will help stop the virus from spreading to the Americas and reduce the number of people impacted.
