Aotearoa / New Zealand

We give them tangelos, oranges, mandarins. Haven't tried grapefruit but I bet they would like it if it's sweet. You have to cut them so that there's a cross-section of open segments (like how people do for breakfast grapefruit halves).

It's really cool because often they won't go near windfall fruit but as soon as it's cut open and up on a stick or tree they love it. Tui eat it too, especially in winter when there's not a lot else going on.
