Habitat Loss
Definition
Habitat loss encompasses the destruction or degradation of the environments penguins depend on for breeding, moulting, and foraging. For burrowing species like African and Magellanic penguins, coastal development, guano harvesting, and invasive vegetation have reduced available nesting habitat. In Antarctica, ice-shelf collapse eliminates breeding platforms for emperor penguins. On sub-Antarctic islands, introduced predators like rats and cats have made once-safe breeding grounds dangerous. Habitat loss is rarely the sole threat but compounds other pressures like climate change and food scarcity.
