These pictures show two eagles clawing at each other in a mid-air confrontation in Poland.
The two birds of prey scrapped and lunged at each other while flying inches off the ground in what the photographer said was a ‘power play’ between the two eagles.
The duel took place over grassy ground and above a pool of water, with other nearby birds watching cautiously and appearing to take evasive action.
Dutch photographer Jessica Blokland van Diën said she had travelled to Poland last winter to take the pictures where many of the eagles gather during the coldest season.
The 33-year-old said she had ‘made it my mission’ to capture the images, saying that in her home country it was unusual to see them so close up.
She said: ‘Even though they come together does not mean they are social creatures. If an eagle came to close to an other bird or tried to steal it’s food it would turn out into a fight sometimes between several birds at once.
‘The fights look very aggressive but it is more showing of who is boss than wounding each other what you see in the photo’s is mostly powerplay between one and other.’

Claws out: One of the birds bares its talons with its wings spread out while the other flies just above the grassy ground, with another eagle watching on behind them in the Polish field
Mid-air meeting: The two eagles appear as though they are about to collide with each other as they both reach out with their claws, their eyes trained on each other. Another of the birds left, looks as if it is trying to take evasive action
