Today will probably go down in the annals of great Jersey birding stories. First it was a Black Guillemot at Sandy Hook; this would've gotten more respect except for the long-staying (in guillemot terms) bird at Barnegat last winter. Then it morphed into a Pigeon Guillemot; this would be an East Coast mega. Finally the word settled on Long-billed Murrelet, a first state record (obligatory disclaimer: if accepted).
Harvey Tomlinson's post on JerseyBirds provides a good discussion of birding "in the heat of battle," when an identification can be more fluid than one would expect. Harvey analyzes which species names were in play and why.
This is on top of a Band-tailed Pigeon (it would be the second state record if accepted) that has outstayed the first state bird by two days now. It (briefly) reduced the list of NJ rarities not seen in Cape May County, but now the murrelet has redressed that balance.
Then there are the continuing Hunterdon County Ash-throated Flycatcher and Western Tanager. If you want a write-up bird, there are plenty to choose from.
