Lorikeet heaven. You could teach them to eat lettuce leaves too along with mango. It is nice to live near nature. You captured great Lorikeet behaviour. You live in an interesting community.
They have nests in the trees of the playground and are usually hanging around on nearby red bottlebrush trees. Initially they were afraid of apples and pears until they tasted it but I guess that's why the word teach was used when mentioning lettuce and mango. I'm presuming anything sweet and juicy will do. They absolutely love nectar mix, bought for the babies, devoured by the adults. I should upload a clip of that
