Soils from 18 parrot collpas ('clay licks') in southeastern Peru averaged four times more available sodium than uneaten control soils. Collpa soils contained marginally more clay than control sites and clay content was uncorrelated with available sodium content. Parrots may select and ingest soils based on available sodium content.
