I am a native in this world And think in it as a native thinks

Avian fashion

This is a Galapagos dove, along with another swallowtail gull. It is interesting how many of the bird species unique (or endemic, as the naturalists say) to the Galapagos have such vivid eye rings.

For the gull, which is the only nocturnal gull in the world, the red ring may have something to do with improved night vision. For the dove, I think it's just a fashion statement.
