Irritated Jay Birds.

A lot of noise coming from the bottom of the garden led me to witness a Magpie flying off  leaving 2 Jays in distress. This short video shows a sample of their behaviour which lasted 40 mins after the Magpie's departure.  What had occurred or why they seemed intent on removing all the thorns from the Sloe Bush wasn't clear.  Any ideas?
