Morning melody
Geese flutter by in a "V"
Open eyes to see.
(ASL 4-17-12)
So, this morning I had a little time on my porch before school. With my Bible and a piping hot cup of coffee, I settled in to the "symphony" of beautiful birdsong all around me. I had no more started to thank God for the delight of the moment, when suddenly a flock of geese came squawking by above me. It was as if the Lord said, "You're Welcome."
I shared my happy morning with my students and told them of the geese in perfect "V" formation. And then, as usual, came the questions. "Mrs. Lamb, why do they fly in "V" formation?" And then, my usual answer, "I don't know. God just made them that way."
So I came home and "googled" it. And here is an explanation I found:
Why
do geese and some other birds fly in a V formation?
New Scientist in 2002 published several contradictory
possibilities. But we liked this reason from Charlie Bateman
(slightly edited):
“A goose's eyes are set in the sides of its head, giving
good all-round vision but leaving a small blind spot directly ahead
and behind. If a goose were to follow directly behind the one in
front it would have to turn its head slightly to see it clearly and
would have to resort to asymmetrical flapping to maintain a
straight course, reducing its aerodynamic efficiency and wasting
energy. It would also have to fly a little below the one in front
to stay clear of its wake, not a good place to be as geese defecate
in flight. This leaves some kind of echelon formation as the only
practical solution.”
There are other advantages to flying in a V formation. For
example, experiments have shown that 25 geese flying in a V can
travel 70% further than solo birds. The birds function more
efficiently in a group working together.
Now couldn't you just
break out in a shout to glorify the
Creator of the geese who implanted this marvelous ability in the
birds? Of course you could. God has planted some amazing abilities
in birds (
mallee fowls take
temperature,
penguins navigate to land
from far out at sea, etc.). But compare that with what
New
Scientist said:
“Putting these observations together suggests that there
is more than one advantage to flocking, and that aerodynamic and
social benefits may have evolved together.”
“May have evolved together”? The wisdom of this
world is truly foolishness in God's sight
(1 Corinthians 3:19).
I can't wait to share this with my class tomorrow. What a privilege that we can, indeed, "break out in a shout to glorify the Creator of geese who implanted this marvelous ability in birds."
