Canada Geese (Branta canadensis) take off from a small pond at dusk with the lead goose flying in front of the formation. The lead goose expends the most energy because it is the first to break up the flow of air that provides additional lift for all of the geese who follow behind the leader. When the lead goose gets tired, it drops out of the front position and moves to the rear of the formation where the resistance is lightest and another goose moves into the leadership position.
This Bald Eagle (Haliaeetus leucocephalus) flew into the salt marsh scattering all of the birds except the Ospreys (Pandion haliaetus) either to the far remote corners of the salt marsh or completely out. The Ospreys are not afraid of bald eagles. In this photo, it appears the Bald Eagle is chasing the Osprey but it is the opposite. The Osprey is above the Bald Eagle and is shadowing it to keep it away from the Osprey nests.
