Hello John,
The answer is non-trivial.
But in a brief nutshsell, if you added Sooty/Dusky Grouses to your aba list using the same internal thing as that referenced by the same birds in your 2007 list, then all would be right. You can determine this by using the Rosetta Stone feature in BD.
Let's start here and have you ask questions if this does not give you what you need.
