- One side of the line is longer than the other because...Linda guessed it! There are more geese in it! This everyday mystery is solved! Fun Science Facts from the Library of Congress says this.."Why do geese fly in a V? Energy conservation and visual assurance. Why do geese fly in a V? Because it would be too hard to fly in an S! Just kidding. Scientists have determined that the V-shaped formation that geese use when migrating serves two important purposes: First, it conserves their energy. Each bird flies slightly above the bird in front of him, resulting in a reduction of wind resistance. The birds take turns being in the front, falling back when they get tired. In this way, the geese can fly for a long time before they must stop for rest. The authors of a 2001 Nature article stated that pelicans that fly alone beat their wings more frequently and have higher heart rates than those that fly in formation. It follows that birds that fly in formation glide more often and reduce energy expenditure (Weimerskirch, 2001).
The second benefit to the V formation is that it is easy to keep track of every bird in the group. Flying in formation may assist with the communication and coordination within the group. Fighter pilots often use this formation for the same reason." That's all from that above link. - I asked a Canadian friend if different sized flocks were from different provinces, and her answer was 'no'. Deadpan. I got a kick out of thinking it, did you?! Likely, they just found a different thermal or something. This from www.chacha.com/: A flock of geese flying in formation can move faster and maintain flight longer than any one goose flying alone, this is synergy. Answered -
- Yes. Mama geese tire of the constant "MaMaMa" of the little geese. However, I like to think the extended family is flying together, so she couldn't be sure it's her baby or her nephew or niece. So, as is almost always the case, she'll keep her cool longer if it's not her own child, right? Besides, it's kind of hard to 'pull over' in the sky, no?
- Family meeting of where to go? Doubtful. I think, rather, that they draw straws (or pinfeathers!)
- Yes. The little geese say, "Are we there yet" about the time they hit WY. (also, see #3.)
Thanks for checking in. Daddy and Jonathan went up skiing today, so it's the little girl and I at home. Maybe I could get caught up on my blog?
Love your comments! Please leave one so I know who's checking in...
Happy days!

Fascinating Geese Info!
I always get amused seeing the blackbird travel conventions - hundreds of them all in rows up on powerlines. I'm sure they're discussing which route to take this year and techniques to deal with the kids and who gets to go first and who gets the cushiest bushes en route.
