<sod>The Topknot Pigeon has a solely frugivorous diet which varies throughout the bird's range. This is due to the fruit, of the trees and palms this pigeon feeds on, ripening at different times during the year.  In Northern New South Wales the diet consists of native figs, species include ''F, rubiginosa, F. stephanocarpa, F.stenocarpa, F.eugenioides, F.infectoria.'' Fruit from the Bangalow palm, ''Archendophoenix cunninghamiana'' and other rainforest  fruit trees, ''Elaeocarpus bunerleni, Eugenia smithii, Heicarya augustifolia and Melia azaderach w''hite cedar.(3) Topknot Pigeon shows a preference for small fruit from 5 to 25 millimetres is size.(4)  Although common in the rainforest habitat of this pigeon, ''Ficus watkinsiana,'' Watson's fig  are not eaten by this pigeon due to the size of the fruit, 50 millimetre in diameter.(3) In southern New South Wales in the Winter and Spring, ''Cryptocarya microneura,'' is the main stay of the bird's diet. As Spring continues ''Elaeocarpus kirtonii,'' pigeon-berry Ash, ''Acronychia laevis'' hard aspen and ''Eugenia smithii'' lilly-pilly are eaten. As Summer approaches the birds begin to feed on species such as ''Schizomeria ovata'', white birch, ''Citronella moorei'' silky beech and ''Pennantia cunninghamii'' brown beech until the native figs are ripe ''F.eugenioides s''mall-leaved Fig and ''F. marcophylla'' Moreton Bay fig then become the mainstay of their diet along with the seeds of ''Livistonia australis'' cabbage tree palm.  On  the Atherton Tableland, Queensland,  Topknot pigeons feed on ''Acronychia acidula'' lemon aspen, ''Garcinia cherryi'' cherry beech, ''Elaeocapus grandis'' silver quandong, ''Balanops australiana'' pimpleback, ''Planchonella euphlebia'' hickory boxwood and native laurels.(4) During periods of native fruit shortage, Topknot Pigeons will eat the small black berries of ''Cinnomomum camphora''  camphor laurel.(3)<eod>
