I found a tree in Tess's paddock last year and it had eggs of a Rosella in it. There was 6 eggs. Every single day I went to that hole in the tree to see if the eggs had hatched. The Mamma bird soon got used to me going to visit her daily and didn't skwark at me or antyhing. Turns out only 4 of these eggs hatched. I still watched them every single day and saw them grow up. The rate that they grew was so rapid I was shocked! After about 2-3 weeks I went to see the hole in the tree and Mumma bird and all 4 babies were gone :(
Went back to the house all depressed that I didn't get to see my birdies fly away when I saw 4 young Rosellas land on my fence! I was so happy that they "came to see me" before they left! They lit up my day just going to visit them and see them grow up! The hole has never been touched by another bird again.
Heres a pic of them 1 week old
