Both parents share all tasks associated with the raising of the young, from incubation to the rearing of ducklings. The ducks, primarily cavity ...
For larger birds, flying in flocks reduces the energy cost. Geese in a V formation may conserve 12–20% of the energy they would need to fly alone. [27] [28] Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (2.5 kn) faster in flocks than when they were flying alone. [16]
