Brent Goose (Light-bellied)
|Scientific name:||Branta bernicla hrota|
Winter migrant from high-Arctic Canada. Most occur in Ireland between October and April. This population winters almost entirely in Ireland, with small numbers in parts of Britain and France.
Small dark goose, with a black head, neck and breast, and dark-brown upperparts and pale underparts. Almost whitish flanks, and small white crescent on the upperparts of the neck visible at close range.
Gutteral 'rhut, rhut'
During the winter, it feeds mostly on eel-grass, which grows on muddy estuaries, and also on grasslands, usually when coastal supplies have been depleted at estuarine sites.
Nests in small, loose colonies by coastal tundra, with pools and small inlets.
Mostly found on coastal estuaries during the autumn and early winter, and also on grasslands from mid-winter, until departure for the breeding grounds begins in late April.
Irish Wetland Bird Survey & an annual special survey in October and January each season. In addition, a number of geese have been colour ringed over the past 10 years and sightings of these can be reported to Graham McElwaine, the Resightings Coordinator, Irish Brent Goose Research Group.
Common Winter visitor. Highest numbers (c. 30,000) are seen at Strangford Lough in Northern Ireland in October, where most congregate on arrival. Thereafter, they move to other estuarine sites. Lough Foyle in County Derry, Dublin Bay in County Dublin, Tralee Bay, Lough Gill & Akeragh Lough in County Kerry, Rogerstown Estuary in County Dublin, Wexford Harbour & Slobs in County Wexford are other well-used sites (1,000-3,500 birds)
Breeding in Svalbard, Greenland and Canada.

Geese and Swans return to Ireland for the winter
Greenland White-fronted GooseThe first Greenland White-fronted Geese of winter 2019/20 arrived on the North Slob in Wexford yesterday (01 October 2019) - four adults and a juvenile. The Greenland White-fronted Goose is the species on the BirdWatch Ireland logo. If you want to get a good look at this species, make sure you visit Wexford Wildfowl Reserve this winter. Later this month there will be a number of public events for their annual 'Goose Week' and they will also be celebrating the 50th Anniversary of the reserve.
Light-bellied Brent GooseThe first Brent records of 2019 came at the end of August, which isn't actually unusual, though the bulk of birds arrived several weeks later (and are still coming!). When they first arrive in Ireland they head en mass for Strangford Lough. After refueling there, they gradually disperse around the Irish coast as the winter goes on. Many Brent have already returned to their usual haunts in Donegal, Derry, Louth and Dublin, where they'll feed on eelgrass and algae in the sea, before turning to terrestrial grasslands for a few months before making the return journey back to Canada!
Pink-footed GooseOne of the first records in Ireland this year was via the WWT's Kane Brides who informed us of a satellite-tagged bird that arrived from Iceland on the 4th of September, spending a couple of hours in Roscommon before heading to Carlingford Lough on the east coast that night. Small numbers of Pink-footed Geese winter in Ireland, but hundreds of thousands winter in the UK and stop in Ireland en route from their Icelandic breeding grounds. Since the start of September there have been loads of Pink-foots (Pink-feets?!) spotted in Donegal and smaller flocks in Wexford, Louth and Dublin.
Greylag GeeseIn the last few days there have been multiple reports of large flocks of Greylag Geese at coastal sites in Donegal. Greylags are a tricky one - we have a resident population that breeds here, but we also get migrants from Iceland for the winter too. And there's no way to tell which is which in the field as they look the exact same! Donegal has many feral/naturalised Greylag Geese, but some of those recent large flocks probably have some Icelandic-migrants mixed in too. Barnacle Geese The first 'Barnies' of the season touched down in Donegal at the start of this week. This species prefers coastal grasslands and offshore islands in the west and north-west. Because of the remote locations they use, the NPWS recently carried out a Barnacle Goose census by plane!
Whooper SwanThe first definite migrants have only appeared in recent days - in Donegal, Derry and today in Wexford. In the last census, there were nearly 12,000 Whooper Swans in ROI and >3,500 in NI. The I-WeBS office in BirdWatch Ireland, together with our colleagues in Northern Ireland and further afield, will be coordinating another census of Whooper Swans in January 2020 so please keep an eye on your local flock as the winter progresses! So there you have it - thousands of geese and swans are currently migrating from Iceland, Greenland and Canada to spend the winter in Ireland! Many of these species are of conservation concern and we're lucky to have the wetlands to support them, so do keep an eye out for them in your area as the winter goes on!
Each winter we monitor Ireland's waterbird populations through I-WeBS - a survey coordinated by BirdWatch Ireland, funded by the National Parks and Wildlife Service, and carried out by a network of bird surveyors who volunteer their time and expertise.
The I-WeBS office is interested in any records of Greylag or Pink-footed Geese this winter - please email us at firstname.lastname@example.org with numbers, locations and dates.
