When hummingbirds disappeared from the Old World, insects like long-tongued bees could have taken over their pollination duties, Mayr speculates. The next-oldest, modern hummingbird fossil......scopic food, while the surrounding wetlands make a perfect breeding ground. "Most people think of flamingoes as delicate birds that live on tropical beaches and palm trees," said Arengo.
