These birds are referred to as Nectarivores and mainly consume nectar & pollen from flowering plants. Species include lorikeets & lories as well as honeyeaters, wattlebirds, miners, sunbirds and hummingbirds. These birds may also eat exudates such as sap, manna & lerp, fruits, as well as insects for additional protein. Nectarivores have a specialised brush-tipped tongue which is an adaptation for gathering their liquid nectar diet. These birds have relatively simple digestive systems so should not be fed large amount of starches (grain) and fibre.
