Aging and damaged brain cells, or neurons, can cause memory problems and limit the brain's ability to recover from illnesses. Some scientists have posited that if we could just turn on the ability to make new neurons in the brain—a process called neurogenesis—some of these deleterious changes might be reversed.
"It's the way they walk. That's what the main attraction is," said self-described amateur birder Sheeba Garg, who traveled to Bryant Park specifically to see the American woodcock during its migration.
"They didn't even try to fly away. They just feebly made noise," a woman told the Santa Barbara Independent on Saturday after spotting over two dozen dead or dying cormorants near Goleta Beach. "A few were on their stomachs, wings spread [and] gasping for breath.... Heartbreaking."
A comprehensive analysis of Google search patterns related to birds explores what species people seek information about most frequently. The investigation spans six interconnected analyses examining bird variety, taxonomic classifications, information sharing behaviors, birder sighting correlations with search trends, regional popularity differences across states, and temporal patterns in search interest.
Around a third of UK gardeners use pesticides, and our studies found that house sparrow numbers, for example, were nearly 40% lower in gardens where the pesticide metaldehyde was used. By reducing pesticide use, you can actively encourage birds back into your outdoor spaces, as they rely on invertebrates such as slugs and snails as natural prey.
Video showed officers Michael Russo and Patrick Memi along with Sargeant Michael Amello and Detective Nicholas Martin in their boat pulling up to the eagle on the river. The bird was screeching in distress as the officers used a pole to keep the ice chunk near their boat and worked to catch the animal. "His claw's bleeding, too," one of the officers said as they grabbed a catch pole and carefully put it over the bird's body.
Cetti's warblers barely existed in Britain in my childhood, with just a handful of sightings. But since the first breeding record in 1972 they've made inroads. Nowadays, if I visit a watery reserve and don't hear one, I write a strongly worded letter of complaint to the relevant authorities.
On a quiet Montreal street of low-rise brick apartment buildings on one side and cement barrier wall on the other, a crowd has gathered, binoculars around their necks and cameras at the ready. A European robin has taken up residence in the neighbourhood, which is sandwiched between two industrial areas with warehouses and railway lines and, a few blocks away, port facilities on the St Lawrence River.
Many people look up to admire the silhouette of raptors, some of the planet's largest birds, soaring through seemingly empty skies. But increasingly, research shows us that this fascination runs both ways. From high above, these birds are watching us too. Thanks to the development of tiny GPS tracking devices attached to their bodies, researchers are getting millions of data points on the day-to-day lives of these apex predators of the skies, giving us greater insight into where they hunt and rest.
Animals' risk of becoming roadkill depends on several factors, including how many vehicles are on the road, how many animals are on the road, and how animals and human drivers behave, explains Tom Langen, a professor of biology at Clarkson University, who studies animal-vehicle collisions. DST can minimize these collisions, however.
Nearly half of the 261 species studied showed big enough losses in numbers to be statistically significant and more than half of those declining are seeing their losses accelerate since 1987, according to Thursday's journal Science. The study is the first to look at more than the total bird population by examining the trends in their decrease, where they are shrinking the most and what the declines are connected to.
