Smart male sparrows shuffle their playlist to woo females!
Anybody will tell you that if a repertoire of songs is played in the same order more than once it becomes tedious. Hence, the sequence needs to be shuffled to break the monotony and that is what male sparrows do – remix and rearrange their songs to keep intact the love interest of the female, a report in smithsonianmag.com stated.
As per the details of the study published in Proceedings of The Royal Society B, the songbirds keeping track of every new song they sing, change the order every half an hour to keep the females wondering.

Singing and songs are vital for the male sparrow as that is the way to win over a potential mate and battle for breeding territories.
In order to know more about their songs, scientists went to the northwest Pennsylvania woods to record several hours of trilling and chirping. Following recording of more than 30 individual birds, they proceeded to their laboratory to chart the songs to find out the order in which they were sung and their duration.
It was found that males did not go through their songs on a random basis rather they curated and planned their own playlist. Bachelor birds avoided repeating the same tune by ensuring that they select and put together six to 12 different two-second soundbites while performing which may go up to 30 minutes as per a report in NPR.
