54:1471982-04-14Lake CorneliaHennepin(vote 4-2, with one abstention, and with 6-1 required for acceptance) This was another difficult decision, with the majority convinced by the description of very small size in comparison with Herring and Ring-billed Gulls standing nearby, the "white foreheads ," yellow bills, and "yellowish" legs. However, the minority was bothered by the lack of direct size comparison with other terns, the failure to note black tips to the bills, and the fact that the observer was looking south somewhat into the sun and may not have been able to determine bill and leg color accurately.
