2 days agoSwifts spark joy!' Why these beautiful birds need our help and 10 ways to give it
Swifts are declining in population due to habitat loss and reduced insect availability, necessitating conservation efforts.
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.
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.
