The story varies.
In any case, Galápagos mockingbirds are also distinctively different from mockingbirds on the mainland. And they are different from one Galápagos island to another.
Which leads, step by painful step, to Darwin's theory of evolution and the eventual publication in 1859 of On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. Phew.
Sidebar drama: Interestingly enough, as a Christian, Darwin was troubled by the implications of what he discovered. However, when a naturalist pal of his, Alfred Wallace, came up with a parallel theory, Darwin's misgivings subsided enough for Darwin to polish up his own manuscript and send it to a publisher. It became an overnight sensation.
While we were doing our own exploration in the Galápagos (zero collection of specimens, thousands of photos, great guides, and a tidy ship thanks to AdventureLife), we stumbled across a little mockingbird family drama on Floreana.
I've got a theory or two (as usual) about this scene. It might be a long-held rivalry between the matriarchs who were born sisters but grew to their own greatest rivals. It might be a fresh incursion between an upstart gang and the Boomer family they rejected.
Or maybe it's a daily show staged to entrance the tourists –– 14:00-15:20 beached walrus pups, 15:20-15:40 mockingbird display, 15:40-whenever tortoise crossing.
