Penguins already spend time preening and lounging on land, but they could adjust their position to maximize exposure to the Antarctic sun. This might help regulate calcium for stronger bones, just like humans get vitamin D.
While complex tools might be out of the question, penguins could potentially use pebbles or other smooth objects to break open shellfish or pry stubborn mollusks from rocks.
Penguins already share feeding duties for their chicks, but they could extend this by sharing hard-to-find food sources within their colony, benefiting the entire group.
Some penguin species huddle together for warmth, but they could take it a step further. Imagine penguin highways – snow tunnels dug by the colony to provide protection from harsh winds while traveling between nesting sites and feeding grounds.
While penguins have a complex vocal repertoire, mimicking basic human signals like pointing or nudging could improve communication within the colony, especially for dangers or new food sources.
The Antarctic sun can be harsh. Penguins could learn to spend mid-day hours seeking shade under rocks or using their feathers to cover sensitive areas, mimicking how humans use hats and sunscreen.
Penguin parents already share incubation and chick-rearing duties, but this could be extended to other colony tasks. Imagine penguin shifts for guarding nests or taking turns taking a dip in the ocean to cool down.
