Scientists reveal yet another reason fig trees are titans of biodiversity

Not only do farmed figs feed humans, they also provide food for fruit eating and insect eating birds. Their fruit attracts tiny wild pollinators – perfect as a food source for insectivorous birds.

Biologist David Mackay got a surprise when he began studying the birds visiting fig trees in his native Australia: While he expected to see plenty of species coming to eat the figs, he didn’t expect the insect eaters to outnumber them two-to-one. Mackay already knew that figs feed more bird species than any other fruit. His research, published in June, would show that fig trees are disproportionately important for insect-eaters, too. It adds to growing evidence that fig trees are titans of biodiversity with important roles to play in conservation. Altogether, Mackay recorded 55 bird species visiting Ficus rubiginosa fig trees to feed on insects. They included ten species — such as the superb fairy-wren and the shining bronze-cuckoo —whose recent declines in numbers have concerned conservationists.
