They may be cute little creatures, but as these pictures show blue tits can be just as territorial as any animal.
A photographer captured the rare moment a pair got involved in a tussle while out in his local park.
Scott Williams, 54, took these pictures in Ayr, Scotland, after spotting the two birds coming to blows.
He had visited the park to snap some of the local wildlife and managed to spot the pair whilst looking down his lens.
The pictures show the two blue tits squabbling on the floor as one of them is pinned down by the other.
Photographer Scott said: ‘I was trying to photograph some birds in flight and noticed these two birds having a squabble in-flight.
‘They landed in a furious ball of feathers and I laid on the ground to try to get a good angle of the birds.
‘The fight itself lasted for a good couple of minutes and was ferocious.
‘I am pretty sure from the last photo that one of the birds lost an eye.
‘I must admit, I thought one of the birds wouldn’t survive the fight but thankfully they both flew off at the end.’
