Terrific capture, especially with that one wing out. Did you know that a group of vultures in flight is called a kettle, but if perched they are a committee? I work a lot with committees and find this endlessly amusing.
Terrific shot Kate... I remember when the beautiful peacock landed on the roof... he was much prettier that these guys. I love the pose you captured here.
I like the way the birds are inserted into the tree background, especially between two small trunks going upwards to an open sky zone that you have kept in the frame. That provides some movement in the image. I also like the posture of the two birds, it is almost a Valentine picture.
