It's something that I don't think gets enough attention, the way light pollution does. But its' definitely a problem in some places. And I can see how it would disrupt bird calls.
It does in German speaking parts of Europe - highways on weekends and during the night have speed limits set to reduce noise.
There are cases where this is kind of like English, in the case of buy/sell 买/卖, but still quite different
Should have gone with "Friendship!" VS "Friendship?"
If your parser can't handle that, then it's literally dumber than a tit.
Video is 5 years old. Seem pretty cool. Steampunk parrot.
I guess this is the guys original channel
The conclusion is that the birds interpret the sequence ABC - D as a meaningful unit, different from its constituent parts, which is a kind of interpretation only previously confirmed in humans.
Of course it could also be because he correlates environment cues to bed time.
Either way, birds are smarter than you think until you spend time observing them.

He used to say his name sort of (if you added some human pattern recognition magic) but stopped after we moved apartments. No idea why.
The worst is when he mimics human speech patterns. You can tell it isn’t words but it’s close enough to distract you every time.
Main thing with parrots is that they’re more work than people think. Like human children they get bored, have tantrums, internal emotional states, and respond to the same stimuli differently based on mood. And unlike children they cannot be reasoned with. Some are smart enough to lie and obscure because they have theory of mind.
And they stay like that for 30 years. Some species even longer.
I still eat meat, but I do wonder what paper is going to get released that is the tipping point for me; it's easy for me to justify eating meat if I think these animals are so stupid that they can't feel higher-level emotions, but if we have legitimate evidence of animals having "uniquely human" traits, I can't help but think that us eating them is sort of ungodly cruel.
That said, anyone reading this post is probably not a lion or a bird, and has some level of self-reflection as a result. Just to play devil's advocate for a bit, couldn't you argue that if it's possible for me to live a fairly healthy life without killing any higher-minded creatures, then I should? If we are smart enough to have an entire philosophy of ethics, then shouldn't we be using this ethical framework to minimize suffering in the world?
I should reemphasize, I'm not a vegan, or a vegetarian, I have a fairly typical American diet of "it's not a meal without meat" sadly. I'm just saying that these kinds of papers make me question that.
 I'm not a biologist or doctor or anything, but my understanding is that cats (at least house cats) cannot product their own vitamin A out of Beta-Carotene like humans can, and must get it out of animals. I certainly cannot blame any animal that is doing what it absolutely has to for survival.
That said, animal models are extremely common for NIH-funded work, and birds feature prominently in studies of language and auditory processing.
