Scientists investigated the pollination of four species of plants. Each of the species was treated in three ways: some plants had their flowers covered to exclude pollinators, other plants were not manipulated, allowing birds to pollinate them, and a third group was pollinated by hand using a paintbrush. The percentage of the total flowers that developed into fruit was recorded.
Which species of plant is most efficiently pollinated by birds?
