Yuko Hattori described the findings as 'fascinating', noting how the chimpanzee used tools to produce various sounds while expressing a vocal display.

The fireflies were most likely to change their own flashing rhythm in response when the LED blinked almost, but not quite, at the same time as the fireflies. The males would speed up their next flash if the LED blinked just before and waited a bit longer for their next flash when the LED blinked right after.

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.

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.

I'm seeing a ton of smart bird feeders again this year at CES - and I'm inexplicably drawn to them. Perhaps because the idea of birds nibbling on seeds and flying away represents a natural purity and freedom that doesn't exist within the halls of CES. Birdbuddy was one of the first smart bird feeder brands, with a wildly successful Kickstarter back in 2020. And this year, they've added birdsong to their species identification capabilities.

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.

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.

While migratory birds do fly south for the winter, many seed- and insect-eating birds do not, and with leaves off the trees, the winter months are often the best time to watch them. As someone who tests smart bird feeders year-round for WIRED, I'm always interested in ways to ensure I'm attracting the largest and most interesting variety of birds to my yard, no matter the season.
