Which bird has the loudest song in the world?
It was the curse of love, and Cat began to think about which bird sang the loudest. A chirping magpie at the window? Too vulgar. The crow croaking loudly along Chang'an Street? Too funereal.
The whole point of the world's top - white bell (bell) bird , it can definitely love song into an alarm clock.
When the first note is uttered, the male begins to spin around, the long, black, fleshy droop on his head (cockatoo-like tissue, some bellbirds have several) becomes whip-like, endangering his partner, and emits a piercing second sound directly at the female. At this point, the female knows that this one is spinning again and jumps back a few steps. Next, if she is satisfied with the intensity and volume of his song, love is in the air.
This species involves a lot of involution.
Scientists have measured the average volume of the male's song at a staggering 125.4 decibels (at a distance of 1 meter). That's roughly the same as standing on the deck of an aircraft carrier while a jet fighter takes off alongside. The association doesn't work, well, you're standing in the middle of a square and two groups of unqualified square dancers are screwing the volume of several stereos to the head in your left and right ears ......
Scientists have found that hidden beneath the male's white plumage is a muscular, Greek-sculpted chest with tissue five times thicker than most birds of its size. And, of course, it has a bill that opens very wide - as they say in comedy, a big beak makes a big call.
Use it as an alarm clock, no problem at all.
