As requested by Michael I have attached a graph showing the A values for starlings.  Note that:

  • The series start at Year 2, since the data for starlings is somewhat distorted by observations of a large roost in Year 1 which was not used in subsequent years; and
  • I have deliberately used the same scale for both series to contrast the peak numbers of the two species.

I will let others consider the biology underlying these series.
