Who ever said birds were stupid? They were quite wrong. Many birds are quite intelligent and we get a fine chance to observe this intelligence in the migration of geese.
Everybody can associate geese flying in a ‘V’ formation with fall; the geese head south for the winter and are most often seen flying this way. Down here in Texas, we can often see Cattle Egrets flying this way, demonstrating their often overlooked wisdom. There is actually an intelligent method behind this flight, showing us that birds are smarter than we think.
Birds fly in a ‘V’ to save energy; by traveling this way, they render themselves as a group, more aerodynamic. If these birds were to fly in an unorganized group, flying would be a lot harder. Picture it this way; which car is more aerodynamic, a sports car or a dump truck? The sports car is by far the more aerodynamic of the two, its sleek form enabling it to reduce drag, therefore allowing it to go faster. When the geese and the egrets fly this way, they render themselves more aerodynamic, reducing the wind they have going against themselves and therefore applying less energy into flying. The bird flying at the point of the V though, has all the wind going against him, however this is not permanent. Studies have shown that after flying at the point for some time, upon becoming tired, the lead bird will drop to the back where flying is the easiest, and take a well-deserved break. This just goes to show that birds are a lot smarter than we think.
