Can birds do drugs?
If you mean “can birds knowingly go out and acquire illegal psychologically modifying chemicals for recreational use” I would say definitely not. However, birds can and have been observed getting totally sauced on various delicious fermented fruits.
Waxwings and robins will gorge on thawed berries until some of them are so inebriated that Environment Yukon has taken to keeping the worst off in tiny bird drunk tanks until they’re sober enough to leave. Inebriated zebra finches sing like they’re at terrible karaoke night. Drunk parrots periodically fill animal hospitals in Australia. A flock of intoxicated starlings stopped traffic in Austria after running into numerous cars. THE LIST GOES ON.
As mentioned in the video, hilarious to hear about but in reality it is causing a major problem; these “drunk” birds have a hard time avoiding head-on collisions with buildings and other man-made paraphernalia. Moral of the story: don’t drink and fly, kids. Unless you’re a bat. Because it turns out you don’t need to pass a breathalyzer test to fly with sonar.
