Rainbow Lorikeets - Trichoglossus haematodus - are birds similar to Rosellas and the Swift Parrots. They are excellent flyers, and have a distinct set of brush-like barbs on their tongue. They use these abilities for collecting nectar from wattles flowers, eucalypti. They are swift and acrobatic, often flying at speeds of over 50 kilometers per hour. At dusk they nest in large congregations sometimes there are 30 or more in one large tree making the sound pervasive with the hectic comings and going on. They have distinguishable ranibow plummage, and are 30 to 50 cenimeters long, making them fairly small for a parrot.
