Friendship is God's Gift

When two persons are fighting and you had to join.
There is only one way, which is going with anyone of the two.
But, if the same two persons are friends and you had to join,
Three can share equal respect and be respected by a fourth person.
Friendship knows only oneness; it gives no place for selfness.

note: I captured only three birds in the sky, had to mix three snaps for the clouds sake ;-) and to get Hi5 birds. So, question is : which two birds are repeated in this image?
Here is one original image
