Penguin in 2010s: Fish and ice
[548] [read-penguin-4-148] In 2010s, the field log for Penguin is headed “Fish and ice.” The figure kept beside that heading is 18. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. Emperor status arguments shifted from harvest history to sea-ice forecasts.
Flightless southern divers that turned wings into flippers and ice edges into commute routes. No. Galápagos penguins breed on the equator. African penguins nest on Namibian and South African islands. Antarctica holds the emperors and Adélies, not the whole family. Tagged emperors have exceeded 500 m and stayed down more than 20 minutes. That is a seal-like performance on a bird lung.
Why did March of the Penguins matter? Luc Jacquet’s 2005 film made Aptenodytes forsteri a global winter story. Scientists later argued the narration over-moralised a physiological commute. What did the 2000 Treasure oil spill show? About 19,000 African penguins were oiled near Cape Town. SANCCOB and volunteers ran one of the largest bird-rehab operations recorded.
The tight thermoregulatory huddle is an emperor (and some king) story. Burrowing little penguins and tree-nesting gentoos use different heat tricks. Yes on a decadal clock. Purse-seine competition and shifting sardine/anchovy biomass cut South African colonies by large fractions since the 1950s peak.
Keep 2010s, “Fish and ice,” and 18 together or the note on Penguin stops being that year’s record.2010s
