Common on the red flowering gum trees, all their heads 

 and throats being covered with the pollen of the flowers. Their 

 note greatly resembles that of the Common House Sparrow 

 (Passer domesticus), and they are a noisy bird. When flying 

 they are graceful in the wing, and very swallow-like in their 

 movements, keeping at a great height, sometimes almost out 

 of sight, but still uttering their single note.
