For the first time we’ve looked at every threatened bird in Australia side-by-side

New research has shown how to measure conservation progress for Australia's 238 endangered bird species
The composition of black and white in a magpie’s poo differs between species. Some splatter more of the uric acid (white), some have more black (indigestible solids). It depends on their diet. Gisela Kaplan

Curious Kids: Why is a magpie’s poo black and white?
