Anecdotes from around the world describe wild animals—everything from wasps to songbirds to baboons—acting drunk after feeding on fermented fruits. But these incidents are assumed to be rare and accidental, and the scientific literature largely treats alcohol consumption as a uniquely human behavior.

Now, a team of researchers are challenging this view. They cite growing evidence that fruit- and nectar-eating animals likely consume ethanol (or ethyl alcohol) on a regular basis - though the reasons are understudied.

Good fences make good neighbors—and good conservation tools, according to a new study. Analyzing nine years of data, researchers confirmed that beehive fences are highly successful at deterring African elephants from crop-raiding small farms, protecting both wildlife and livelihoods. The elephants’ natural fear of bees keeps them away, and the farmers also generate an income through honey and wax production.

The scale of the illegal wildlife trade is enormous and threatens many animal and plant species. Around the world, international ports need more resources to screen shipping containers for smuggled wildlife. According to new research, help could arrive soon—in the form of trained rats. A proof-of-principle study shows that African giant pouched rats can successfully learn to detect the scents of pangolin scales, elephant ivory, and other illegal wildlife products.

Recent work suggests that female song was the norm for the ancestors of modern songbirds. And many female birds still sing today: It is estimated that female song occurs in about two-thirds of all songbird species. Despite the increased documentation of female birdsong in recent years, questions remain about its function. Male songbirds use song most often to attract mates and defend territories. Why do females sing?
