I know the Emperor Penguins take a while to lay and hatch an egg, but the male is the one who incubates it. Meaning the male is the one to keep the egg warm, then the mother comes back when the egg is ready to hatch and they raise the baby together.
"The female lays a single egg, which is incubated by the male while the female returns to the sea to forage; parents subsequently take turns foraging at sea and caring for their chick in the colony. The lifespan is typically 20 years in the wild, although observations suggest that some individuals may live to 50 years of age."
