BBS Methodology - Point Counts [page
a BBS Point Count (continued)
no method of coaxing birds should be used during the 3-min counts.
If uncertain about the identification of a bird detected at a
stop, it is okay to occasionally spend a minute or two after the
count verifying the identification. But this should not be done
habitually or for extended time periods because you may exceed
the time limit for completing the route.
- Do not count any individuals known or strongly suspected to
have been counted at a previous stop. This situation can often
occur with soaring species like vultures and some raptors.
