Territorial Disputes at the bird feeders

Having spent half an hour yesterday cleaning out the bird feeders as they were in such a manly state there was plenty of action around and on them this afternoon at least prior to the rain. This is another of my still shots from as 4K capture and show two greenfinches scrapping over the top right perch. Some of the shots of the birds taking off were rather blurred and I think I need to be shooting at a far higher shutter speed in order to capture this movement but when the birds had their wings fully spread I managed to get a sharp enough image.
