1. Acacia Seeds: Rainbow lorikeets have been observed consuming the seeds of various acacia tree species, such as the black wattle (Acacia mearnsii) and the golden wattle (Acacia pycnantha).
2. Banksia Seeds: They may also eat the seeds of banksia trees, including the Banksia integrifolia and Banksia serrata. These seeds are contained within the banksia's characteristic flower spikes.
3. Bottlebrush Seeds: Rainbow lorikeets sometimes feed on the seeds of bottlebrush trees, such as the Callistemon viminalis and Callistemon citrinus.
4. Eucalyptus Seeds: Occasionally, rainbow lorikeets may consume the seeds of certain eucalyptus tree species, but this is not a regular part of their diet.
5. Native Grass Seeds: Some rainbow lorikeets have been known to eat the seeds of native grasses like kangaroo grass (Themeda triandra) and wallaby grass (Austrodanthonia spp.).
It's important to note that the seed-eating behavior of rainbow lorikeets is not as pronounced as in other types of parrots that primarily rely on seeds. Rainbow lorikeets are mainly nectarivores and frugivores, and seeds only supplement their diet occasionally.
