Final answer:
The seabird puffinus puffinus, commonly known as the Manx Shearwater, stands out among birds for its use of the uropygial gland to waterproof its feathers and its ability to fly, which differs from other birds such as penguins.
Step-by-step explanation:
The seabird that has the scientific name puffinus puffinus is known commonly as the Manx Shearwater. This type of seabird is different from others like pigeons, parrots, hawks, and owls because those lack a uropygial gland but have specialized feathers that "disintegrate" into a powdery down serving a similar purpose. Contrarily, a puffinus puffinus, like many sea birds, uses this oil from the uropygial gland to waterproof its feathers. For example, a penguin and a seagull also have wings, but the penguin uses wings to swim whereas the seagull and the Manx Shearwater use wings to fly. This ability to fly makes the puffinus puffinus, or Manx Shearwater, a unique and interesting seabird.
