November 2009: Black Brant at the
Lower Rosses, Drumcliff Bay
This Black Brant is the subspecies of Brent Goose that normally breeds
in western Canada and winters on the Pacific coast of the USA. A
Black Brant has been seen with Light-bellied Brent in this area in
recent years in autumn.
As seen at Isle of Islay, Argyll, Scotland November 2002
As seen at Lissadell, Sligo, Ireland - November 2009
The mismatched pair of Canada/Cackling Geese currently with the Barnacle Goose flock at Lissadell bear a superficial resemblance to an similarly mismatched pair photographed at Loch Gruinart on the Scottish island of Islay in November 2002, and published in the Winter 2002/2003 edition of the magazine "Birding World".
However, closer scrutiny of the photo shows a clear size disparity (thanks to those who pointed this out) - the Scottish birds are clearly smaller. In fact the larger of the two Scottish birds is similar in size the the smaller Sligo bird, with the other Islay bird even smaller. Two further images of these birds kindly supplied by the photographer and co-author of the Birding World article put this beyond doubt - see below.Chris also comments that the 2002 Islay birds were only very loosely associated with each other, whereas the 2009 Lissadell birds seem strongly bonded.
See Batty, C. Lowe, T. and Millington, R.(2003) Branta goose gallery: Winter 2002/2003 Birding World 16 (3) 108 -113
Further photos supplied by Chris Batty confirm that these Islay birds are different geese (as suggested by Killian Mullarney and Mike O'Keefe), it ios also clear that the long-necked appearance of the Islay bird in the first photo above is a chance effect of posture, it is proportioned very similar to the smaller, probable Richardsons (B. h. Hutchinsii) bird at Lissadell.
Chris's comment on these birds is below:
....both the Islay geese are of the small clade of Canada goose (ie Branta hutchinsii as opposed to Branta canadensis). Furthermore, I believe it is most likely that the smaller, darker bird is Branta hutchinsii minima - which I think is not as unlikely a vagrant as is traditionally supposed - and the larger, paler bird is a Branta hutchinsii hutchinsii. However, our ability to identify these birds to race/form has been questioned (and indeed the classification of these races/forms in North America has itself been questioned). I have used scientific names only to avoid the somewhat confusing common names attributed to these birds."
Thanks to all whose input has helped clarify this issue.
23rd November 2009: Storm Petrel found dead at Lissadell on Monday by Noel Raftery. The bird was found along the woodland walk to the hide at the Goose Field, which runs along the shore.
22nd November 2009: Storm Petrel seen flying along the water's edge at the Alpine Gardens, Lissadell on Sunday evening by Declan Skehan - the same bird found the following day a mile east by Noel Raftery (above)?ay

Part of the huge gull flock feeding on the stranded starfish at Lissadell Strand (John's port end). The starfish numbers seem to have gone up again, possibly more still coming ashore.

The possible hybrid Glaucous-winged Gull still present on Lissadell Strand, in a flock of c. 1,000 gulls, mostly Herring Gulls, but with an increasing component of Great Black-backed Gulls

The Canada and Cackling Geese were recognisable and stayed close together in flight as a flock of 100 Barnacle Geese approached the Lissadell Goose Field at lunch time

6th
November 2009:
An unusual mass stranding of a common species of starfish (Asteria rubens) occurred at on Lissadell Beach, where Drumcliif Estuary meets Drumcliff Bay. The casue is unknown, but is probably a result of the resecnt protracted perid of stormy weather, at a time when there are spring tides, alowing the wave action to scour the bottom.
