Watching the Geese In Flight

In the blue sky of sunshine There are white patches of clouds Joining them is a flock of geese Flying in a V formation,honking As they pass by my house How do they stay as one Without bumping into each other Flying evenly together Without losing their rhythm? It does fascinate me As I watch them flying by I notice their southern pass To somewhere very warm Water blue,grass is green Spending their winter there I go to the window and look to the sky To watch all the action that is taking place Until they have passed on their way Then I go on with my work Happy that I have seen their flight
