The other day on my way back from doing some errands, I saw a large flock of migratory birds in a very long V-formation. It was one of the longest perfect V-pattern I have seen for a while. Since I was driving through a less traveled dirt road, I was able to stop and snap a picture of it.
It was an amazing sight to say the least, with their wonderful flight formation, and all 100 or so of them (yes, I counted them), maintaining their alignment.
Why do birds fly in the V-formation anyway? Studies have shown that they do this to catch the updraft wind created by the flapping of the wings of the one preceding them. This make their flight more aerodynamic and efficient. But what about the bird in the very front? It is doing all the hard work, right? Well, it was observed that they take turns on being the lead flyer. Interesting.
As I was watching them, I have noted that they were heading North. A little more Northwest to be exact, according to the compass on my iPhone. That means this cold winter is finally ending and spring is coming, as the migratory birds are coming back home from their migration down south.
Another question that comes to mind is how do they navigate their way without using GPS? Research indicates that they employ many techniques like using the position of the sun or the stars, or rely on big landmarks like lakes or mountains. But the most fascinating part is that birds seem to have a built-in compass in their brain, like a magnet, that can sense the Earth’s magnetic field, so they know which way is North and which way is South. They do have GPS after all.
Yet the most intriguing part to me is why do these migratory birds fly back North to the place where they were born (or hatch) every spring? They could have stayed in the South where it is always warm and save them all the trouble of flying so many miles. Do you suppose they do this to earn frequent flyer miles? Every year they come back to the place where their parents raised them, a place where they spend the first summer of their lives. They do always come back home.
I don’t think only migratory birds are like that. I think many creatures including us, humans, long to go back home. There might be innumerable hassles in traveling back. There may be chronic ills pestering the land where we came from. Yet there is something magical to that place where we were born and raised. Something more than mere nostalgia. Something much deeper. And it does not matter how far we have wandered away. It does not matter how long we have been gone. The connection and pull of that place we have once called home is always there.
I was musing with all this flying home subject matter when I was interrupted by an announcement overhead. I adjusted my seatbelt and looked outside my window.
I am nearing home.
