When it comes to speech, parrots have the gift of gab. And the way the brains of small parrots known as budgerigars bestow this gift is remarkably similar to human speech, researchers report March 19 in Nature.

Backyard bird has a lot to teach us about sex variability
(scientificamerican.com)
It’s springtime in your backyard. You watch a pair of little brown songbirds flit about, their white throats flashing in the sun. One of the birds has striking black and white stripes on its crown and occasionally belts out its song, “Old Sam Peabody, Peabody, Peabody.” Its partner is more drab, with tan and gray stripes on its head and brown streaks through its white throat.

Repeat offenders may be responsible for many shark attacks
(nautil.us)
Veterinarian-turned-shark-expert Eric Clua knows how rare it is for a shark to attack a human. While dogs kill some 30,000 people annually, only 100 shark attacks are documented worldwide each year, and fewer than 15 percent of these are fatal. Still, he wants to understand why sharks attack when they do.

The Alpha Myth: How captive wolves led us astray
(anthonydavidadams.substack.com)
In 1947, at Switzerland's Basel Zoo, animal behaviorist Rudolf Schenkel peered into an enclosure of captive wolves, meticulously documenting their interactions. What he witnessed – aggressive displays of dominance, rigid hierarchies, the emergence of an "alpha" male – would spawn decades of misunderstanding about power, leadership, and masculinity.

Peeing is contagious among chimps

When ya gotta go, ya gotta go, and if it sometimes seems like the urge to pee seems more pressing when others nearby are letting loose—well, there's now a bit of science to back that up. It turns out that humans may not be the only species to experience "contagious urination," according to a new paper published in the journal Current Biology.

Ants prove superior to humans in group problem-solving maze experiment

Anyone who has dealt with ants in the kitchen knows that ants are highly social creatures; it's rare to see one alone. Humans are social creatures too, even if some of us enjoy solitude. Ants and humans are also the only creatures in nature that consistently cooperate while transporting large loads that greatly exceed their own dimensions.
