Thanks to BGould I acquired three pair of Yellow-rumps a few months back and they've fledged three young already. They built in a brush filled wire basket and it appears they're starting to sit again
I have noticed a fair bit of 'aggression' between the pairs (just a bit of hardcore chasing) so maybe splitting them up into ajoining aviaries will allow the other pairs to breed.
Anyways heres some pics and thanks again to BGould
