Charlene et al.-

Yes, eBird follows the American Birding Association rule referenced by Charlene (copied below). If you see a Lava Gull sitting in the Maple Island Parking Lot at Riverlands Migratory Bird Sanctuary it is an Illinois bird no matter where you are physically viewing it from.

RULE 1: The bird must have been within the prescribed area and time-period when encountered.

A. Within means that the bird must be within the prescribed area when observed, although the observer need not be. For example, if an observer on the U.S. side of the Rio Grande identifies a bird across the river on the Mexican side, the bird may be counted on his Mexican list but not on his ABA Area list.
