The Audubon Magazine blog has a summary of the early results. Some of the unusual reports included Yellow-billed Loon, Yellow-billed Cuckoo, Rustic Bunting, and Rufous-capped Warbler. You can see what else was reported on the GBBC's "explore the results" page.
Among the things you can see on that results page are the species reported in each state and locality. The lists are sortable, so it is easy to see which birds have been reported the most at a variety of geographic levels. You can also see data presented in map form and view reports for individual species. Below are two tables of species reported in New Jersey.
The first shows the species that were reported in the greatest numbers.

Canada Goose | 36408 | 426 |
American Crow | 25306 | 716 |
Dark-eyed Junco | 17439 | 1930 |
Common Grackle | 16458 | 586 |

There is nothing surprising on New Jersey's top ten lists. Birds like Snow Goose and Canada Goose gather in large flocks, so they appear in large numbers on relatively few checklists. Downy Woodpecker and Tufted Titmouse range widely, so they show up on many checklists, but birders usually only see one or two at a time, so they appear in the GBBC results in smaller numbers than other common birds.
One question going into this year's GBBC was how much the Pine Siskin count would differ from last year. In 2009, the GBBC recorded 7,848 Pine Siskins on 664 checklists in New Jersey. This year, New Jersey birders reported 185 siskins on 52 checklists. The difference is remarkable and emphasizes just how extraordinary last year's irruption was.
