The diet of the masked shining-parrot consists mostly of soft fruits such as guavas, figs and bananas, but it also consumes flowers, seeds, berries and insects (3) (4). This parrot is usually found high in trees, but will sometimes descend to lower levels to feed (4). The masked shining-parrot is quite agile in the trees, often moving about by using its beak to help grip onto branches (4) (6).
Although it is usually seen alone or in pairs, the masked shining-parrot will also gather in small flocks, particularly outside of the breeding season (3) (4) (6). This species is typically seen flying swiftly through the forest or above the tree canopy, with bursts of flapping punctuated by regular glides on spread wings (4) (6).
The masked shining-parrot makes its nest high up in the treetops of the forest, often in a crack or hole in a tree or stump (2) (4), which the birds may enlarge using their powerful beaks (4). Breeding takes place between July and September (3) (4), and females lay clutches of two or more eggs (3) (4).
