Humans have long made playlists to express their love towards a potential partner, and new research suggests some birds not only do the same, but can rotate the order.
This "cycle" of songs acts like a playlist and can last for up to 30 minutes. Once it is over, the sparrows will change the order of the songs in the playlist each time it is sung. In order to collect the data needed to answer this question, Nowicki's research partner William Searcy, an ornithologist and biologist at the University of Miami, hiked into the backwoods of northwest Pennsylvania with equipment to record hours of the birds' songs.
This analysis indicated that male song sparrows keep track of their tweets intentionally, as the males generally sing through their entire repertoire before repeating any of their songs. It also indicated that the longer the sparrows sing a particular two-second song, the longer they would wait before singing it again.
