I am starting a Life List for the third time.
What are the rules for adding a new bird to the list? I've seen some comments about varification of the bird required by another person. If we are in a group and someone points out a bird and says it's a Yellow-rump Warbler, can we count it even if we don't see the identifying marks? Can we count a bird if we hear it and someone says it's a Song Sparrow but we don't see it? If we are by ourself and identify a bird using a field guide, can we count it?
Or is the life list rules based upon the owners own personal guideline? We didn't count the Downy Woodpecker until we actually saw a Hairy Woodpecker. The Greater and Lesser Scaup are still on our "Wait and see" list since they are always too far away. And why do the Pied-billed Grebes look so much larger down in Texas than they do in Illinois?
