THE BACKSTROKE BOYS
ếch hợp thành "ban nhạc" để thu hút ếch cái đến ao...
A frog (ếch) species (loài) forms 'boy bands' that sing in unison to woo females into their pools, a new study shows.
Researchers have recorded wood frogs (Rana sylvatica) at ponds in New Hampshire to learn more about individual contributions to a frog chorus (dàn hợp xướng).
Findings indicate that females are generally attracted to songs in lower frequencies – likely because they indicate bigger bodies and good physical health.
Males, meanwhile, time their songs to other chorus members and may even be choosy about singing with certain other males to enhance their breeding success.
In this way, they're akin to boy bands choosing the right bandmates to enhance their appeal to the ladies.
A frog chorus is made up of individual calls of various frogs, creating a cacophony of bizarre quacking or gobbling sounds.
