Musk Lorikeets are bigger and have a longer tail than Purple-crowned Lorikeets, G. porphyrocephala, or Little Lorikeets, G. pusilla, and are smaller than Scaly-breasted Lorikeets, Trichoglossus chlorolepidotus, with a much shorter tail. The Musk Lorikeet has obvious yellow patches on the side of the breast in flight and a prominent red band on the face. The call in flight, a harsh rolling screech, is also helpful.
