This Nature Outlook is editorially independent, produced with financial support from Avadel. Miranda cannot remember a time in her life when she did not have insomnia. The 23 year old, who asked for her last name to be withheld, started struggling with sleep when she was a child. As she’s grown older, it’s only become worse. She takes “a myriad of medications” each night, she says, but usually still cannot fall asleep until the early hours of the morning.

This Nature Outlook is editorially independent, produced with financial support from Avadel. I never had issues with sleep until the COVID-19 pandemic. A couple of months into lockdown in 2020, I found myself unable to fall or stay asleep. My worries played on an unstoppable loop, and the longer I lay in bed, the more anxious I became about not sleeping. This vicious cycle left me exhausted. After a few months, I became depressed.

But for the Anna’s hummingbird, a common species in the western United States, feeders have become a major evolutionary force. According to research published this week in Global Change Biology, artificial feeders have allowed the birds to expand their range out of Southern California up to the state’s northern end. They have also driven a transformation of the birds themselves.

If you’ve ever really looked at how flamingos eat, you know how captivatingly peculiar it is.

Three cooperative birds and a model bird head helped scientists figure out what flamingos are actually doing when they stick their heads upside down underwater. "Just as spiders produce webs, flamingos produce vortices," Victor Ortega-Jiménez, an integrative biologist at the University of California, Berkeley, said. Credit Credit...

Continuing the birds-are-awesome theme: Hummingbirds in California have evolved new beak shapes and massively expanded their range—thanks to feeders. They've basically become the equivalent of backyard pigeons! @ScienceMagazine https://t.co/eWcIuVMOnP
Human preference for smooshed, baby-like faces has produced pedigreed cats and dogs that are more similar to each other than to their wild relatives, and have such distorted skulls that they could not survive in nature. @sciam https://t.co/GnL3UQfQPi
Yet more evidence that birds are awesome: Flamingos harness the physics of fluid flow to create vortices that sweep up prey and funnel it directly into their mouths. @NYTScience https://t.co/4XS7U7Bszp
