According to scientists, city Great Tits prefer other city Great Tits over country Great Tits. (Lets act like adults). The researchers found that the city dwellers responded more strongly to songs of fellow city dwellers and the same held true for the bumpkins. The average minimum pitch of male Great Tit songs in noisy urban areas was higher than in quieter, rural areas just a few miles away. Dr Rupert Marshall, of Aberystwyth University, Wales, and his team recorded bird song in 20 different cities in Britain. He says, "People speak louder and higher in noisy places like pubs and bars but still recognise their friends' voices once they go outside. Great tits seem to learn the high notes from their neighbours but don't respond as strongly to lower rural tones even when it's quiet."
