As numbers of marine mammals have decreased and human use of coastlines has increased, the Andean condor diet has changed to include one-third to one-half less marine-derived food than a century ago. This influences their movement patterns, with some birds foraging up to 86 km from near-coast nesting sites and over a mountain range to find food. The worldwide reduction in marine-mammal carcasses may have major consequences on the foraging ecology of scavengers, as well as on the influence of marine nutrients within terrestrial ecosystems.
