Penguins Move Enmasse on South Sea Isle to Guard Eggs (Sep, 1929)

It’s been a long time since writers who mentioned a penguin had to explain what one was.

Penguins Move Enmasse on South Sea Isle to Guard Eggs

COVERING every available piece of land on a small island in the South seas, hundreds of thousands of penguins, strange aquatic birds shown above, tend their eggs during the period of incubation. The birds have a general elliptical shape with a neck of moderate length. Their heads are small with a comparatively long bill. They have no quills in their wings, which are useless for flight. However, their flippers move freely from the shoulder joint, making good paddles for swimming.
