General Comments
The Violet-green Swallow is a reasonably common breeding species of open montane forests of the western parts of Canada and the United States, ranging south into Mexico. It is highly migratory, and it winters mainly from Mexico southward, though some birds winter in coastal CA. Thus, one would expect that, sooner or later, an individual of this species would be seen in NC. However, highly aerial species such as swallows and swifts can be difficult to document photographically, which indeed was the case of the first valid report from NC. The NC BRC accepted the description of one seen (only in flight) at Lake Davidson (Mecklenburg) on 5 May 2016* (Chat 81:1-4). However, as photos are voted on separately from written descriptions, the blurriness of the photos (due to great distance of the bird from the photographer) led the NC BRC to not accept this documentation. Thus, according to records committee regulations, a species accepted by a written description but not verified by photograph, specimen, or audio recording is placed on the Provisional List, which does give the species a place on the Accepted List. It should be noted that there was a previous report (in 2011) from another Piedmont county that was accepted, with photographs; however, it was later determined that the photos were taken in another state and therefore the NC BRC later rejected this erroneous report (Chat 78:17-39).

The Provisional List contains species for which there are less than three accepted sight (i.e., non-documented) records. Species of unaccepted origin are not included on the List of Bird Species of North Carolina.

The species can easily be overlooked as a Tree Swallow. It seems more likely to appear in NC as a fall migrant than a spring migrant, as most Western migrant species appear in Eastern states in fall more so than in spring. Thus, observers need to carefully scrutinize flocks of Tree Swallows for this rarity, as well as for other rare swallows such as the Cave Swallow, which does occur with Tree Swallows mainly in late fall along and near the coast.
