Researchers across the pond discovered
that Great Tits living in cities perform "a kind of avian rap" while tits living in rural areas create "a gentler and more relaxed birdsong."
A study of 10 European cities, including London and Paris, and forests found that birds in urban areas are more likely to use staccato notes at a higher pitch, and tweet in a brasher way, than their country cousins.P.S. Please keep the comments clean.
In the world of bird harmonics, researchers say it is akin to an avian hip-hop.
"We've shown that in 10 out of 10 comparisons, the city birds sing with a higher minimum frequency, on average, with less low notes," said researcher Hans Slabbekoorn at the University of Leiden in the Netherlands, who conducted the study. "They sing faster and consistently start their phrases with shorter notes compared to their counterparts in the forest."
