2017 THEME : A Push For PreventionWorld Penguin Day is observed on April 25. The day was timed to coincide with the annual northward march to the sea of Antarctic penguins, as autumn edges toward winter in that part of the world.
Antarctic penguins in particular are vulnerable to climate change, with shifting ice reducing where they can live and warming seas affecting their prey.
2/3rd of the world’s 18 penguin species, whose habitats range from the equator to Antarctica, are in decline.
