2 Emperor Penguins
While their modes of survival are quite different, emperor penguins still make good moms, even though they aren’t exactly doting. After laying an egg, the mother leaves it to travel far and wide, sometimes up to 50 miles, leaving the egg in the care of a male penguin.
The reason for the trek? To find food. When she returns, it’s just in time to feed the regurgitated fish to her new babies who are freshly hatched. It’s not the fanciest first meal, but surely the baby penguins are glad to have mom back to keep them safe and warm.
