Mwnt is now established as our
migration ringing site for Northern and "Greenland" Wheatears, but last
night the target was Storm Petrels to start providing more information
about the birds in this part of the Irish Sea. It would be interesting
to establish if these are passage birds, or are they on feeding trips
from their breeding colonies on the Pembrokeshire Islands.
Well, we are no further in answering the question...
Caught in the first month of Storm Petrel ringing at Mwnt one of our birds shows interesting movements around the Irish Sea. A likely faithfulness to this area of sea......and surely could be a breeding bird by 2017.
If a breeding bird on feeding trips, where is it from....
Here is an up to date summary provided by staff as appropriate to each "local" colony. (exc Eire)
The figures are for AOS - adults on site.
Skokholm 2000+ - the largest colony.
Bishops and Clerks...163
Bardsey .....175 pairs
IOM ....20 pairs - ? (not from island staff)
We have captured 38 new Stormies this year, and with 2 retraps we hope to add to the picture..
Tracking of birds would assist, and we are aware of the difficulties in tracking Storm Petrels.
