But in Australia, a steep rise in atmospheric temperatures is leading some Zebra Finches to emerge early and gain an elder-sibling advantage, according to recent research published in Royal Society Open Science. This slight edge allows bigger first-borns to get more food from their parents, lowering the odds that other chicks in the nest will survive.
