This was my second night out with Miha Krofel, a conservation biologist at the University of Ljubljana, driving rural roads through farmland and forests. The night bef
A North American snail kite in Florida. Researchers say the bird species has rapidly evolved larger beaks and bodies to eat a larger, invasive snail.Credit...Robert Fletcher/University of Florida Conservationists have been sounding the alarm over invasive species for years, warning of the damage they can cause to habitats and native animals. But in Florida, an invasive snail might be helping an en
Whales and songbirds produce sounds resembling human music, and chimpanzees and crows use tools. But only one nonhuman animal is known to marry these two skills. Palm cockatoos from northern Australia modify sticks and pods and use them to drum regular rhythms, according to new research published in Science Advances on Wednesday. In most cases, males drop beats in the presence of females, suggesti

The birds were twice as likely to offer sustained help to Yao foragers who walked along while playing recordings of the proper brrr-hmm signal than they were to participants with recordings of normal Yao words or the sounds of other animals. “The fact that the honeyguides were responding more to the specialized sound implies they recognize the specific information content in the signal,” Dr. Spott

A unique species called the island fox has lived there for several thousand years, their bodies shrink
A handful of scientists and policy makers are circling the same question, grappling with the long-term environmental effect of an economy that runs increasingly on gotta-have-it-now gratification. This cycle leads consumers to expect that even their modest wants can be satisfied like urgent needs, and not always feel so great about it. The new arms race for Internet retailers is speed, making the
