A group of 21 endangered birds at the Bronx Zoo who spent seven loveless years together have finally produced offspring thanks to a little dose of mood music.
What kind of music you might ask? A recording of mating calls of wild ibises.
Call it the Barry White strategy for romance in birdland.
Bronx Zoo ornithologist Mark Hofling tells the New York Daily News that the endangered Waldrapp ibis have at long last produced chicks - six of them.
Piping the sounds into the enclosure via IPod led to courting, nest building and egg laying. The success story in New York comes after a failed attempt last year to encourage breeding at the Philadelphia Zoo's indoor ibis display.
Bronx Zoo officials say they are now thinking about trying out the same libido therapy on Caribbean and Chilean flamingos.
