I have a regular flock of Crimson Rosella's and King Parrots which pop in for a feed of seed when I am home. Some of the King Parrot's have become very tame and will eat out of my hand. The Crimson Rosella's are easily excited and nervy but have two that will feed out of my hand.
With both species I have noticed that they are all totally infested and lousy with louse, always scratching.
The other day I had a very old female King Parrot sitting on my knee feeding and noticed a fly like insect nearly the size of a blow fly come out from under her feathers and then go back under again further down the wing.
I have seen this type of fly insect on Feral Pigeons, so it must be a common bird louse. I pity the parrots always scratching as it must drive them crazy. Otherwise, it doesn't seem to affect their health or plummage in any way.
Does any one know what this fly like louse is called, the juvenile parrots have also got it, most likely passed on by the parents in the nest.
