"In my view, a "good bird" is one that even a resident birder would get excited about finding...a species that one might expect to encounter only once or twice every few years of active birding."  Irons, David.

By that standard, I am comfortable describing the simultaneous appearance of two "Very rare" birds within a few hundred yards of each other on the Oregon Coast as a SPECIAL OCCASION. Very rare birds are defined in (Marshall, David B., Matthew G. Hunter, and Alan Contreras. Birds of Oregon: A General Reference. Corvallis Or.: Oregon State UP, 2006. Print.) as "No more (observations) than 1 per day or 1 per season."

According to my reading of the history books, the DICKCISSEL and the NORTHERN MOCKINGBIRD have never been observed in the same location in Oregon before this season.
