Big
Day Information
A "Big Day" is an effort to locate and identify
as many species within a given state or county in a single
calendar day as possible. In essence, the official Big
Day rules require that there be a team that travels together and
stays within voice contact distance at all times (except during
"time outs" when no birds may be counted). Whenever any member
of the team sees or hears a new species for the day, he or she
informs the team and all team members must attempt to confirm
that identification. In other words, everybody tries to confirm
every bird claimed by the team and, at the end of the day, 95%
of all species recorded by the team must have been recorded by
every team member (this assures higher accuracy by a
quick-moving team). No prearranged meetings with other birders
are allowed during the day (in other words, a team cannot have
folks "staking out" birds for them) nor may the team receive
information during the day about where a bird is (unless it
happens totally by accident). Staking out birds and getting
information must all take place before the effort begins. (Above
