A Devious Trick

In the Australian rainforest grows the monkey's earrings tree, so called because of its decorative dangle of seeds. The tree's fruits open up to reveal bright orange interiors that set off glossy black seeds, a contrasting color scheme that birds take as a clear signal that the tree has prepared a tasty meal for them. But looks can be deceiving.

The fruits of the tree have no fleshy, nutritious sections for the birds to derive energy from. Instead, the tree may have developed this color scheme to trick birds into consuming its seeds. While the concept of "fruit mimicry" remains controversial, botanists have observed some young, inexperienced birds consuming the worthless fruit.
