message: I restored the following documented statements because I believe they are relevant and interesting to a reader:
*For mountain quail,  "(introduced to Vancouver Island per Birds of the World, but native according to the IUCN)"
*For California quail, "(Introduced to Vancouver Island; resident in eastern British Columbia)" 
*For greater prairie-chicken, expanded the note to match that in List of birds of the United States.
*For all three of them, I have moved the IUCN citation to follow the Cornell one so their sequence is the same as that of the text.
*I have also restored the (A) tag to American flamingo without the IUCN counterpoint, as IUCN does now agree that it is a vagrant in Canada.

message: This revision made the following changes:
*Revised the status of Labrador duck in the intro; sources agree that its nesting area is unknown (no dispute).
*Revised the notes to mountain quail, California quail, and greater prairie-chicken according to Cornell's Birds of the World. Deleted the IUCN statements because the weight of evidence is that IUCN is not a reliable source of range data (see Wikiproject Birds).
*Expanded the note for house finch.
*Moved those parenthical comments and others to a Notes section.
*Made a few families present in two columns.
