The bottom line, as always, is: it's your list; do as you please. But this
is a poster-child argument for listing NIB (No Introduced Birds). Whether
the doves arrived from the east or expanded along the coast or how-ever,
the species is not native to California or North America. Does that mean
ignore the doves? No. Kimball and his colleagues have shown us that there
is much to learn from following the exploits of exotic bird populations.
But remove the guess work; simplify the rules of the game (which is all it
is), and don't COUNT any of 'em.
