Priority the dating of scientific names in ornithology
Note that the code takes no position on what the species limits are, it only determines the name once those limits are set. Each genus name has a type species (which really refers to an individual bird).
In the case of the Summer Tanager mentioned above, there are many available names.Thus the name Piranga rubra denotes the Summer Tanager.On the Ti F list, it is one of 12 tanagers in the genus Piranga.The fundamental component of his system is a latinate name for every species.Every species name has two parts, a genus name and a specific epithet.The genus, which is capitalized, denotes a group of similar birds, the specific epithet is not capitalized and indicates which of those birds is meant.
You can think of the genus as being similar to a surname, and the specific epithet as acting like a first name.
One, the nominate subspecies, includes rubra and is called Piranga rubra rubra.
The individual cooperi is the oldest named in the other subspecies, and that subspecies is then called Piranga rubra cooperi.
Since rubra was used first, it becomes the name of the species.
The Summer Tanager is currently thought to consist of two subspecies.
Once we've set the limits, we then round up all the named individuals that are part of that species.
