Who/what is decimating our coconuts?

[Dinamight]

The other day I saw a green coconut on the ground under one of our trees and it seemed strange as we had them all removed a few months ago and they usually don't start falling for about a year after that. The next day I saw 2 or 3 more and the next day even more. They have all been gouged out and something has made a huge hole and eaten the flesh. I am thinking there are rats up there but can they eat and destroy that much in just a few days? Birds?

I am constantly seeing new and amazing things here!
