| 86:3 | 2013-05-22 | Lone Tree Lake | Lyon | (record #2013-022, vote 1-9). Apparent adult, photographed. The observer didn't notice this bird in the field but reported it only after looking at the photo subsequent to the actual observation. Therefore, a single photograph is all MOURC had to consider for this potential first state record. Generally, any observation of a potential first state record consisting of a single photograph of marginal quality has a very high bar to overcome, requiring at least nine out of ten votes for acceptance. Several members thought it impossible to rule out the much more likely Black Tern given that the photo was distant and the apparent white wing could simply have been an anomaly or even represent partial albinism. Others thought the white area in the photograph might even suggest something other than the dorsal side of the wing such as undertail coverts while preening or possibly even the underside of the wing. | Not Accepted | ||||
