Birds: King Parrot, Sulphur Crested Cockatoo.

There have been lots of birds visiting our backyard recently. I think they are after the acorns.  It seemed a  good opportunity to practice some bird photography.
I left the camera set up on the kitchen table and yesterday and today rushed out whenever I saw some there.
No luck at all yesterday, and not much today. They either all scarpered as soon as I opened the door, or refused to take off at all till I got sick of waiting with my arm nearly dropping off holding the big lens.
Most of the results are embarrassing but these two are fair. Still not the detail some blippers can achieve, but maybe it's their even bigger lenses :-)
