Paul and Richard,

Here is the excerpt from the ABA web site in regards to what birds are countable for life lists. Specifically, B. (ii) is most pertinent in regards to 'banked' birds:

A. Species means that each full species is counted only once on most ABA lists. Additional subspecies or color morphs are not counted as additional entries except on lists specifically defined to include such identifiable forms. 
B. Currently accepted by the ABA Checklist Committee means: 
    (i) The species must be (a) included in the current published ABA Checklist, as modified by subsequent Supplements, or (b) formally accepted by the ABA Checklist Committee for inclusion in the next published ABA Checklist or Supplement. Species in the category "Origin Uncertain" are considered to be accepted. 
    (ii) An indigenous species currently accepted by the Checklist Committee but observed in the past when it was not considered a valid full species may be counted. 
    (iii) An introduced species may be counted only where and when it meets the ABA Checklist's definition for being an established population. An introduced species observed well away from the accepted geographic area is not counted if it is more likely to be a local escape or release rather than an individual straying from the distant population. 
    (iv) An indigenous species which is reintroduced into an historic range of the species may be counted when the population meets the ABA Checklist's definition of being established or when it is not possible to reasonably separate the reintroduced individuals from naturally occurring individuals. 

Richard, I know that you don't care, but should you change your mind on the subject, you can read the full listing rules at this link:
