An article in the New York Times website discusses the all too aggressive side to hummingbirds. These beautiful birds are much more than tiny bright color birds, for they have an aggressive side that is quite deadly. Hummingbird evolution was sparked by the evolution of plants needing a better method of being pollinated. This had a direct evolution with the hummingbird and its bill, but that bill much soon became more than a means to eating.
Dr. Rico-Guevara and Margaret A. Rubega as a joint study to learn more about the tongues that hide inside this deadly bill.
