Taxonomic Changes

IT’S ALL IN THE NAME!


Here is a list of some of the newest taxonomic name changes for birds.

New common names [highlighted in Bold] for birds found either on the Osa or in the southern Pacific region are listed below.  For other taxonomic order changes or merges/splits, please refer to the American Ornithologists’ Union (AOU) checklist of North and Middle American birds currently in its 7th edition and its supplements (most recently published is the 54th supplement 2013).  Our checklist of birds reflects all AOU current changes.

Violet-crowned Woodnymph is now called Crowned Woodnymph.  The genus and species remain the same (Thalurania colombica).  T. colombica merged with T. fannyi [Green-crowned Woodnymph] due to evidence of an unrestricted gene flow between populations (54th Supplement AOU 2013)

Thrush-like Schiffornis (Schiffornis turdina) is now called Northern Schiffornis (Schiffornis veraepacis).   Thrushlike Schiffornis species complex is now split into 5 different species two of which occur in Central America.  The Northern Schiffornis is found from southern Mexico the western Columbia and Ecuador and is placed in the family Tityridae.  This change was made based on distinction in range overlap, vocalization and genetics. (54th Supplement AOU.)
