摘要：The period covered in this report is 1 July
2001 to 30 June 2002. A total of 69 383 birds
was ringed (Table 1) compared to 82 792 in
the previous year (see Table 7). The total was
made up of 64 689 free-flying birds and 4694
nestlings. There is a fair amount of fluctuation
in ringing totals over the last 5 years
(Table 7), probably mainly due to the number
of penguins and quelea ringed, as mentioned
in previous annual reports. The figures for
this report were compiled in April instead of
the usual December, meaning that the data is
slightly more up to date than in previous
years, although there are always a few ringers
who submit data a few years late.
