The Principles of Migration

Happy Birdwatchers' Day!
12th November, Dr. Salim Ali's birth anniversary, is celebrated as Birdwatchers' Day. Happy birding, folks!

Birds adopt several energy efficient measures to reduce fatigue during their migratory journeys. The characteristic V-formation of migratory geese in one such example. The birds flying at the tips of the V and in front are rotated periodically to distribute flight fatigue equally among the flock. The V-formation has been proven to greatly increase the efficiency and range for long-range migrants, and has even been adapted by military aircraft and airshow flights.
