Goldfinch Behaviour.

Over the last few weeks I have been observing goldfinch at a local feeding station trying to capture images of the birds in flight.There is always a lot of noisy squabbling and threat posturing with these birds and that is all I thought it was until I caught  some images with my camera that froze the action. I could now see how vicious these little birds could be to each other and when two birds were evenly matched in the pecking order the fighting began.They seem to lock bills twisting and turning to see which is the strongest,another tactic is to attack from above with there claws attacking the head and body of the other bird.  I make no apologies for showing the bird feeders and the quality of some of the images as they were taken using ISO 2500. to try an get a fast enough shutter speed to freeze the action in poor light.The whole purpose of this post is to show some of the behaviour of the Goldfinch and even though I have seen them squabbling plenty of times before I have never noticed physical contact until now when my camera captured it.I have posted a few of the images below and would welcome any comments.
