|A noticable sheen but it's not the right colour green.|
There are a few entirely black birds here in Tenterfield but none of them have an actual metallic green sheen in their wing feathers.
When we got home, we went to visit our neighbour, Carol, and I showed her the feather. She told me of some green metallic looking birds she had seen last year/summer in her garden. Carol had told me this sighting before but I forgot about it until when she told me about it again, tonight. Carol described the birds as being the size of Rainbow Lorikeets and they looked similiar in shape. They were eating grass seeds? on her lawn, and were actually on the ground. She saw them from above as she was looking out her kitchen window. The birds all looked green in colour, all basically the same coloured green colour but had a metallic green sheen on them.
This is just complicated now. I do not know of any all green coloured parrot that has a green metallic sheen to it, that lives in Australia. Nor do I know if a green feather, when it falls out of a bird, actually turns brown before it falls out the bird. I do know an all black feather will turn brown before it falls out. I've seen it happen on Australian Magpies. If I knew that then I could perhaps find out if this feather belonged to a parrot-like bird.
One more mystery to solve!
