Description:
Identifying the at-sea distribution of wide ranging 20 marine predators is critical to
understanding their ecology. Advances in electronic tracking devices and intrinsic
biogeochemical markers have greatly improved our ability to track animal movements on ocean-wide scales. Here we show that, in combination with direct tracking, stable carbon isotope
analysis of essential amino acids in tail feathers provides the ability to track the movement
patterns of two, wide-ranging penguin species over ocean basin scales. In addition, we use this
isotopic approach across multiple breeding colonies in the Scotia Arc to evaluate migration
trends at a regional scale that would be logistically challenging using direct tracking alone.
