Taxonomy Changes. All MD/DCRC data products were updated to conform to the latest taxonomy standard, the AOS North American Checklist 60th Supplement, which was published in July. Only a few of the 40+ changes directly affect our regional lists. Below is a summary:
1. White-winged Scoter Split. The Old World Asian taxon [Stejneger's Scoter Melanitta stejnegeri] and the Old World European taxon [Velvet Scoter M. fusca] were split from our North American species. Our North American taxon retains the common name White-wing Scoter, however, the scientific species name changes to Melanitta deglandi.
2. Common Ground Dove Name Change. Hypens were removed from the common names of all Ground Doves, therefore, Columbina passerina is now Common Ground Dove.
3. Storm-Petrel Genus Transfer. Some of our North Atlantic Storm-Petrels were transferred into another genus. Leach's Storm-Petrel is now Hydrobates leucorhoa and Band-rumped Storm-Petrel is now Hydrobates castro.
4. Dark-eyed Junco Placement. This taxon was moved up from following Spotted Towhee to now follow American Tree Sparrow.
5. White-crowned Sparrow Placement. This taxon was also moved up from following Swamp Sparrow to now follow the newly moved Dark-eyed Junco.
6. Oreothlypis Warbler Genus Split. The genus of Oreothlypis warblers was split and some were changed to Leiothlypis. Four of our species are affected: Tennessee Warbler, Orange-crowned Warbler, Nashville Warbler, and Virginia's Warbler. These species remain in the same place, in the same order, but with the changed genus.
Thanks to the MOS Webmaster, Tom Strikwerda for posting these changes.
