The project by Berlin's Natural History Museum, where Darwin works, asks city dwellers to go out and record nightingales' song with their smartphone and upload it onto an app. Through the sound clips collected, scientists are also seeking to map out whether the birds take on "different dialects" in different parts of Berlin. "We keep our parks and gardens in Berlin slightly more untidily, and the nightingales need this," said Darwin. One recent spring morning, a fox slunk past as Voigt-Heucke took a group to check if the Tiergarten nightingale inhabitants had returned from their winter hideout in Ghana. At night, the nightingales' song is aimed at attracting females to nest with them, with some birds known to sing for hours.
