P. Dee BoersmaBioScience, Volume 58, Issue 7, July 2008, Pages 597–607https://doi.org/10.1641/B580707 AbstractFrom the tropics to Antarctica, penguins depend on predictable regions of high ocean productivity where their prey aggregate. Increases in precipitation and reductions in sea ice associated with climate warming are affecting penguins. The largest breeding colony of Patagonian (Magellanic) penguins, at Punta Tombo, Argentina, had approximately 200,000 breeding
