A very timid bird & as you can see in this collage it has one eye on the Lorikeet at all times.
As long as that Lorikeet stays on that dish the Rosella will eat.
Taken through the window.
Oh well captured, they are very timid. We have eastern rosellas here and it the devil of a job to photograph them. Not so difficult with the lorikeets though eh, they pose for you ha ha.
