Protocol: Traveling
0.9 mile(s)
Checklist Comments:    BBC trip.  Numbers are estimates.  Some passerine species have high numbers, but they might actually be undercounts.  The calm and cool morning brought out plenty of bird song and activity and made it easier to here.  Unless there was a new species or a obvious increase in numbers (e.g. barn swallows by bridge), species counts are only for the walk out, not back.
