Hopefully he won't keep going SW when he gets here.....
I got the results about the Kittiwakes back last night.
"Hello Dermot
You are right. Yhese two birds belong to my ringing programme.
1, W/B/m-Y/Bk/G. Born 1999 in Kerisit colony (Goulien, Finistère,
France, 48°05N 04°35W). Controlled every year since 2000, once in 2000,
17 times in 2001. First bred 2002, in i't's natal clifft, failed at
chick stage. Identified as male (behaviour). Bred every year since. On
the same nest in 2003, failed again (chick stage). Moved to the adjacent
cliff in 2004, fledged 2 chicks. Stayed on the same nest for the two
subsequent seasons, but failed (chick stage in 2005, egg stage in 2006).
Moved to an adjacent nest in 2007, failed again (chick stage). Moved to
pointe du Raz colony in 2008, 12 km apart (Plogoff, Finistère, France,
48°02N 04°43W). Failed (chick stage, due to peregrine's predation).
Last sighting : 13/08/2008.
2, m/G-G/Y/W. Ringed as breeding adult male in 1996, Kermaden colony
(Goulien, Finistère, France, 48°04N 04°36W). Raised one chick. Stayed on
the same nest the two subsequent years, but failed (chick stage in 1997,
egg stage in 1998 due to raven's predation). Prospected pointe du Raz
colony by the end of the season. Established in pointe du Raz in 1999
and bred there, on the same nest, every year since : succeeded every
year (total = 11 chicks raised to independance) except 2003 (chick
stage) and 2006 (egg stage). Last sighting : 10/08/2008.
Relating to chick production, 2008 was a rather normal year. The mean
production was 0.6 chick per pair for the whole population (1059
breeding pairs) and 0.7 for the best colony (pointe du Raz). The other
colonies were heavily predated by crows and peregrines. No apparent food
problem : all the chicks regurgitated "normally" when handled.
Many thanks for these informations. Three other Irish people (Dave Daly,
Tony Murray and Dave McAdams) sent me a lot of observations from Wexford
and Cork. Which is quite unusual.
Best regards
JYM"
I mentioned to him that of the 350 or so birds present only 2 were juveniles/first-winters. They do seem to have a hard time when breeding.
