"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 study by researchers at the University of California Berkeley has found that ethanol is surprisingly common in floral nectar, the sugary fuel that keeps pollinators alive. Yeast feeding on those sugars produces trace amounts of alcohol, and in this study, it showed up in 26 of the 29 plant species sampled.

'Our results show that the next 20 years are critical,' lead author Dr Rob Cooke told the Daily Mail. 'By around 2050, we reach a point where the choices we make on emissions and land use will largely determine whether Britain moves towards a much more degraded or a much more nature‑positive future.'

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.

Researchers found that the inclusion of cigarette butts in nests led to significantly elevated hemoglobin and red blood cell concentration, indicating improved physiological condition.

Frogmouths have another life that few people see: like vampires, they wake at sunset and night-hunt until dawn. These stolid creatures turn into zephyrs that silently swoop, catching prey on the ground and in the air.

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.

It's an opportunity for people to get out and see birds without pressure, no matter how long it takes or how many birds we see, said OBara, a retired nurse who has been leading the accessible outings for three years. She said disabled people often cannot keep up on traditional outings, especially when competitive birders are focused on checking off a list of the greatest possible number of species.

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.

Previous research has shown that people feel better in bird-rich environments, but Christoph Randler, from the University of Tubingen, and colleagues wanted to see if that warm fuzzy feeling translated into measurable physiological changes. They rigged up a park with loudspeakers playing the songs of rare birds and measured the blood pressure, heart rate and cortisol levels (a marker of stress) of volunteers before and after taking a 30-minute walk through the park.

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.

When you think of farming, what ingredients do you generally associate with a successful harvest? The basics certainly come to mind: fertile soil, plenty of sunlight and lots of water. But there are other variables that can also mean the difference between a crop of healthy fruits and vegetables and a large heap of organic waste. And it turns out that one of those variables is a very small hawk.

Kakapo breed only every two to four years when the native rimu trees mast and produce large numbers of berries, so repopulation is slow. This year a mega-mast is expected, resulting in a bountiful harvest of rimu berries, which could prompt the birds to produce more eggs. The rimu tree produces berries that provide enough nutrition for the birds to raise chicks. Photograph: Nature Picture Library/Alamy
