Best known for the stunning plumages and displays of the males, birds-of-paradise are found only in Indonesia, New Guinea and eastern Australia. Most are birds of tropical wet forests. They are fairly variable in size and shape, some having fine, curved bills, others having strong crow-like bills. These differences reflect diet preferences: some feed almost exclusive on tender fruits but many are omnivorous. As well as the named birds-of-paradise (of which there are several genera), the family includes the manucodes (Manucodia), paradigallas (Paradigalla), astrapias (Astrapia), parotias (Parotia), riflebirds (Ptiloris), sicklebills (Epimachus and Drepanornis), Paradise-crow (Lycocorax pyrrhopterus) and Standardwing (Semioptera wallacii).
