Hello and apologies for
the radio silence! Since peak hatching was reached we have been
scrambling to keep up with the chicks' progress, leaving us little
time for anything else. In the last week we've had our first
fledglings take flight and things are becoming distinctly calmer
around here,so it's high time we filled you in on the goings-on
here.
A week after we said
our sad goodbyes to our Coquet Island counterparts we re-embarked on
our censusing mission. The combined results of the two censuses gave
us an estimate of breeding pair numbers: 1,633 Roseate Tern pairs,
2,044 Common Tern pairs, and 53 Arctic Tern pairs (compared to 27
last year).

This year's ringing
sweep was a Rockabill reunion, with Brian Burke and Shane Somers, two
seasoned former wardens, returning to volunteer their time. Several
days of concentrated ringing later and all but the most Houdini-like
eligible chicks were ringed. All in all we ringed 1,608 Roseate Tern chicks, 1,826 Common Tern chicks, 5 Arctic Tern chicks and 79 Black Guillemot chicks. This number is still growing, as the younger chicks get to a size suitable for ringing.

Since then we have begun
ringing Kittiwake chicks, with 69 ringed so far. Steve also recaptured a sample of adult Kittiwakes to assess adult survival.

More to come soon,
