Quote:
1. Shiny feathers uniformly overlap to cover a penguin's skin (del Hoyo, et al., 1992). Feathers are highly specialized-short, broad, and closely spaced, helping to keep water away from the skin. Tufts of down on the feather shafts contribute to the insulative properties of the feathers.
2. Penguins have more feathers than most other birds, with about 70 feathers per square inch.
