Among all the species of hummingbirds in Costa Rica, the White-tipped Sicklebill (Euroxeres aquila) has the most incredible adaptation of coevolution with just some specific species of flowers. The bill of this hummingbird has a sickle-shaped curvature of nearly 90 degrees. Due to this the bird can feed on flowers that other species barely can. One more time Nature show us how natural selection works and how it can create jewels like this one!
