Two birds in Brazil are, scientifically speaking, loud as heck, So loud that these relatively small birds rival the earsplitting obnoxiousness of machinery like jackhammers and chainsaws. They’re even louder than much larger animals, like elephants.
According to a study published in Evolution, researchers from the University of Massachusetts Amherst hiked into the Brazilian wilderness armed with laser rangefinders and portable sound level meters to measure the song volume of 123 different species. While hummingbirds let out a gentle 50 to 64 decibels, about on par with a normal conversation, the bare-throated bellbird and the red-legged seriema seemed to be trying to tear a hole in the universe with their birdsong.

This week in science: Loud birds, eating with company, and asteroid samples - NPR
SACHA PFEIFFER, HOST: It's time now for our science news roundup from Short Wave, NPR's science podcast. With me are host Regina Barber and science correspondent Ari Daniel. Hi to both of you. REGINA BARBER, BYLINE: Hi. ARI DANIEL, BYLINE: Hello there. PFEIFFER: So as usual, you have brought us three science stories that caught your attention recently. What three do you have this week? BARBER: How eating with somebody could help manage your blood sugar. DANIEL: Plus, really loud birds. BARBER: (Laughter) And the origin story of Bennu, the asteroid NASA visited to bring back samples. PFEIFFER: Let's start with the blood sugar one. That's very interesting. I'm wondering if you're going to talk to us about the calming effect of a group meal. So tell us what's going on that says that eating with someone could help manage your blood sugar? BARBER: Yeah, so researchers in Israel gave participants the same amount of carbs to eat. So in this case, it was bread. Then they measured their blood glucose levels, and they found, compared to people who ate alone, people who ate together were better at regulating their blood sugar. PFEIFFER: Regulating like it didn't spike as high?
