A familiar sight and sound to our ears this time of year are the flocks of geese migrating to their nesting grounds in the North. They love cold weather, to a certain degree, and they follow it. Such a beautiful, stately bird, they fly fairly low to the ground. They fly in many "V" formations, sometimes in numbers totaling 250,000. The lead bird in the "V" is constantly alternating so that it only has to endure the maximum wind pressure for a set period of time before the position is transferred to another bird. They follow the Great American Flyway which is basically the watershed of the Mississippi River and it's many tributaries, including the Missouri River Basin. They are vegans, they typically mate for life, and are incredibly protective of their young. But there is the occasional divorce and remarriage between them ... is nothing sacred ? LOL !
