The Swordbill Hummingbird pollinates the
Datura, which has a 13-centimeter long blossom that hangs downward. Only the
Swordbill hummingbird can come underneath the flower and put his seven to

pollinate that flower. No other insect or bird is known to pollinate that
flower, so it would simply die if that bird becomes extinct.
