[4] Photographing the dead bird, Snow adjusted "the neck, wing, and tail positions and the cylindrical parts of the body". [4]
Eurasian cranes in a V formation (video) Birds flying in V formation. A V formation is a symmetric V- or chevron-shaped flight formation.In nature, it occurs among geese, swans, ducks, and other migratory birds, improving their energy efficiency, while in human aviation, it is used mostly in military aviation, air shows, and occasionally commercial aviation.
Geese flying in a V formation save energy by flying in the updraft of the wingtip vortex generated by the previous animal in the formation. Thus, the birds flying behind do not need to work as hard to achieve lift. Studies show that birds in a V formation place themselves roughly at the optimum distance predicted by simple aerodynamic theory. [101]
Principles of grouping. The principles of grouping (or Gestalt laws of grouping) are a set of principles in psychology, first proposed by Gestalt psychologists to account for the observation that humans naturally perceive objects as organized patterns and objects, a principle known as Prägnanz. Gestalt psychologists argued that these ...

The female looks virtually identical, but is slightly lighter at 2.4–5.5 kg (5 + 1 ⁄ 4 – 12 + 1 ⁄ 4 lb), averaging amongst all subspecies 3.6 kg (8 lb), and generally 10% smaller in linear dimensions than the male counterparts. [19] The honk refers to the call of the male Canada goose, while the hrink call refers to the female goose. [20]
