Spring is in the air, and the animal kingdom is on the move. Vernal migrations feature everything from fish and birds to big, shaggy mammals and tiny insects. These journeys are about as diverse as the species themselves, but Andy Davis, a University of Georgia ecologist and editor of the journal Animal Migration, says the mass wildlife movements have one important thing in common.

There’s a rocky island in the South Atlantic Ocean so remote that it is known as Inaccessible Island. No humans and few animals dwell there, but among the creatures that call the island home is the Inaccessible Island rail, the world’s smallest flightless bird still in existence. Since the creature was first described in the 1920s, scientists have wondered how it managed to reach its far-flung habitat. Now, as Sarah Laskow reports for Atlas Obscura, a new study may shed light on the enduring natural mystery.
Sloths’ reputation as lazy, slow and stupid creatures owes much to French naturalist Georges Buffon, who described the tree-dwelling mammal as the “lowest form of existence” back in 1749. Buffon’s assessment has endured for centuries, but much of the criticism directed at sloths is unwarranted. As zoologist Lucy Cooke explains for The Day, the sloth’s sluggish lifestyle is a deliberate survival strategy that has enabled it to maintain a place on Earth for nearly 64 million years.

Birds probably know quantum physics better than many humans—it just comes to them innately. Continue reading Scientists Identify Protein That Could Let Birds See Magnetic Fields
There’s nothing quite like the thrill of seeing a rare bird. But not all birds are rare because of their species. Some are common birds that are just… really weird looking.
If you’ve seen BBC’s Planet Earth, you may recall of one of its sillier scenes: the superb bird-of-paradise mating dance. A female hops up to a male, who unveils a mane of feathers and puts on a performance like a drunk rendition of “Bohemian Rhapsody” at a karaoke bar. But when the male bird faces the camera, things go black—way black. Skip to 2:34 in the video below. This bird’s feathers are so black that you can’t see any of its facial features, just radiant blues on a sea of natural Vantablack.
