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.
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.
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.
These caterpillars use a surprisingly complex rhythm like a secret knock to convince the ants to come fetch them. That's according to research published on February 25 in Annals of the New York Academy of Sciences, which found that caterpillars can keep a beat called double meter that has so far been identified only in a couple of primates.
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.
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.
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.
