What the....

We were lucky these birds collision avoidance systems were switched on .They came from directly behind the Phantom and swung around it .Very fast. They might be lorikeets although they have blue heads could even be Superb Parrots which are relatively rare.

Nice capture.
They aren't lorikeets as they are too big, colour/markings are wrong and the tail is too long.
They are the right size for Superb parrots but their speed and small size in the video makes it tricky to see the details clearly.
I've watched the clip several times and tried to get a good ID and it's tricky.
The first bird into the frame in the slo-mo is the best one for id and he's clearly a Superb parrot.
Superb parrots don't have blue heads (the males have conspicuous yellow bibs with a bright red edge).
I suspect the blue heads might be an illusion caused by the fast motion.
