Cоnsider the fаmily Gаvidаe (Lооns- example on left) and the family Laridae (Gulls and Terns, example on right). Loons forage by pursuing fish deep underwater and catching them. Loons require a long running start to get into the air to fly. Gulls and terns eat a variety of foods and use a variety of foraging strategies, including a) pursuing aerial insects, and b) hovering above water and then plunging down to catch fish near the surface. When they are resting on the water, they can lift into the air quickly, without requiring a running start. In which family do you expect member species have greater wing-loading, and why?
