Tale of 2 penguins: Warming climate won't help picky eaters
Two penguin species are responding differently to rising temperatures in the Antarctic, according to a new study. Gentoo penguin populations have almost tripled in recent years while their habitat partners, chinstrap penguins, struggle to keep up. Adaptive feeding strategies that in the past decreased competition for food between gentoo and chinstrap penguins are now proving problematic for the chinstraps.
