Floreana Mockingbird

The Floreana mockingbird (Mimus trifasciatus) or the Charles Island mockingbird, is a species of bird in the family Mimidae.

The Floreana mockingbird is also known as Darwin's mockingbird, as it was the arguable inspiration for Charles Darwin's work on the origins of species; he noticed distinct differences between them and previous species he had encountered and consequently established the existence of other variants on neighboring islands. == Taxonomy and systematics == The Floreana mockingbird, Galapagos mockingbird (Mimus parvulus), Espanola mockingbird (M. macdonaldi), and San Cristobal mockingbird (M. melanotis) were previously placed in genus Nesomimus and were considered conspecific. They now form a superspecies. The Floreana mockingbird is monotypic. == Description == The Floreana mockingbird is 25 to 26 cm (9.8 to 10.2 in) long.
