As this year’s gull chicks begin to fledge, I thought I’d
post a summary of the numbers of chicks colour ringed in the Bailiwick. The
highlight has been 353 Lesser Black-backed Gulls fitted with black colour rings
– a record for us. This resulted from reasonable productivity this year from
the much troubled main colony (c 1,000 pairs +) on Burhou, Alderney, and also a
good season on some of the much smaller colonies on Sark.
Our performance with Great Black-backed Gulls was rather
modest with only 54 chicks colour ringed, but we did better with Herring Gulls
with 210 chicks colour ringed. Herring Gulls in particular had a very
productive season, and this total represents only a sample of the chicks in the
colonies this year.
So…with 617 gull chicks colour ringed this summer, it proved
to be a very satisfactory season. Now I can look forward to finding many of
these juvenile gulls once they’ve left the nesting colonies.
