Ong Ei Leen was the first to post the Blue-rumped Parrot (Psittinus cyanurus) eating the starfruit (Averrhoa carambola) at Singapore’s Venus Loop by Lower Peirce Reservoir in mid-May 2013. This rare resident is a wasteful eater, scattering bits and pieces of the fruit on the ground below in his effort to get at the seeds. This male’s eating behaviour (above) is very much like that of the Tanimbar Corella (Cacatua goffini) LINK. While the Tanimbar Corella removes bits and pieces of the flesh from the fruit ridges to get at the seeds, this male Blue-rumped Parrot tears away the flesh from one end of the fruit. Unfortunately Ei Leen’s video cannot be shown here LINK as there are some problems posting Facebook videos on this website.
Jeremiah Loel‘s video (above) shows the female Blue-rumped Parrot plucking the fruit before attacking it from the end.
Lena Chow‘s video on the other hand shows the male eating the fruit while still attached to the branch (above). The female on the other hand plucks the fruit before removing chunks of the flesh to get at the seeds (below).

The reference below illustrates that the messy eating habits of parrots can in some cases be very beneficial to other useful organisms:
Douglas, L. 2013. “Does the Bananaquit Benefit Commensally from Parrot Frugivory? An Assessment Using Habitat Quality.” Biotropica 0 (0): 1-8.
Thanks for the reference.
Noticed that the bird(s) only go for the unripe fruit. If the birds are really after the seeds any particular reason why they pick only unripe fruit?
Maybe the seeds of the unripe fruits are more tender??? or whatever? Or that ripe fruits become messy when the bird try to to get at them?
