Parula americana
This little Wood-warbler is one of a few birds that has the same common and scientific name and that is the Parula. There are two species of Parula; the Tropical and the Northern. Bonaparte is credited with naming the bird and in Latin the name would be translated as parus, “a titmouse”; and -ula meaning “little”, a diminutive suffix, hence “little titmouse”. The second part of the Parula scientific name is americana, which refers to American.
The other Parula species, the Tropical, only occurs south of the U.S. border. Both of these species are part of a bigger family called the Parulidae - and that includes all the Wood-warblers.
