Summary:
Vocal communication is central to the lives of many birds,
which use sound to attract mates and defend territories. Penguins are no
exception, but we know little about how or why penguin vocalizations vary
between isolated populations. A new study takes a broad look at vocalizations
across the range of Gentoo penguins and concludes that while their calls do
vary from place to place, we still have lots to learn about the processes at
work.
