Status
Winter visitor, from Iceland, northern Europe and western Siberia, mostly occurring between November and April.
Identification
Medium-sized. Males with black head and neck, with white wing bar, are similar to Tufted Duck but distinguished by the lack of a crest, and more elongated shape. Bill pale grey. Females dull brown with pale grey-brown flanks and slightly darker back. A broad white band surrounds the base of grey bill.
Voice
Chorus of low whistles during display, and males otherwise relatively silent. Females drawn out raucous 'krrah krrah krrah'.
Diet
Their diet in winter consists largely of animal matter, principally crustaceans and molluscs.
Breeding
Does not breed in Ireland. The breeding range includes Greenland, Iceland, northern Scandinavia and Siberia, as well as North America. Scaup nest beside shallow tundra pools and lakes.
Wintering
Scaup occur mostly in small parties and occasionally larger flocks around coastal estuaries and bays, on brackish lagoons and in shallow marine waters, usually less than 10 m in depth.

Launch of 45th edition of Irish Birds
The status of Greylag Geese in the Republic of Ireland, mapping of farmland bird hotspots and wintering waterbird trends in Ireland are just some of the many topics covered in the latest edition of Irish Birds.
Published in September 2023, the 45th edition of Ireland’s only ornithological journal is now available for purchase from the BirdWatch Ireland shop and would make the perfect gift for anyone with an interest in birds in Ireland and the latest research in the field of ornithology.
The latest edition of Irish Birds includes an overview of site-level and national trends for 35 wintering waterbird species at the 97 Irish Wetland Bird Survey sites. Across all sites analysed between 1994/95 and 2019/2020, Pochard, Scaup, Goldeneye, Golden Plover, Grey Plover and Lapwing showed large declines of over 50%, while Dunlin and Curlew showed moderate declines. 12 species underwent intermediate declines and the remaining 15 species were stable/ increasing. Further research to determine the drivers of these increases and declines is crucial and will help to shape future conservation efforts.
Farmland birds are one of the most threatened species groups in Europe and many studies have highlighted the declines in population and range of farmland birds in Ireland, the UK and across Europe. The declines, which are affecting sub-groups such as breeding waders and other ground-nesting birds in particular, are attributed to habitat loss and fragmentation, agricultural intensification, land drainage, afforestation and increases in predation. Recognising the important role that agri-environment schemes play in protecting and supporting farmland birds, BirdWatch Ireland has developed a series of maps which illustrate Irish hotspots for 28 species, including Curlew, Lapwing and Yellowhammer. These maps and the methods behind them are included and discussed in another paper – ‘Mapping of Farmland Bird Hotspots: a method to assist targeting of agri-environment measures’ – in the latest edition of Irish Birds.
An assessment of the status Greylag Geese in Ireland during the winter from 2017/18 to 2019/20 showed that the Icelandic population has declined by 42% since the previous assessment in 2007/08. This figure coincides with a c. 45% decline in the flyway population over the same period. Despite these population declines, the distribution of Icelandic Greylag Geese has remained unchanged in the Republic of Ireland over the last 10-12 years, with its concentration being in the eastern half of the country. Meanwhile, the feral population of Irish-breeding Greylag Geese is estimated to have increased by between 109 and 147% since 2008. This study, which was conducted by BirdWatch Ireland in collaboration with the National Parks and Wildlife Service (NPWS), can be read in Irish Birds. To conclude, this paper offers recommendations on how monitoring of Greylag Geese can be expanded upon and improved to help to increase our understanding of this species in Ireland.
Another incredibly informative read is a review paper that looks at the status of birds in County Cork. This paper is a summary of the incredibly detailed book, The Birds of County Cork, by Patrick Smiddy, Mark Shorten and Russ Heselden, which provides a comprehensive account of the ecology of all species known to have occurred in Cork from the earliest times to the present.
Notes on topics such as trichomonosis in finch species and nocturnal migration are some of the other interesting things that owners of Irish Birds can delve into.
The journal also includes a book of abstracts from the 2023 Ornithological Research Conference at University College Cork (UCC) and the Irish Rare Birds Report 2021. The latter is published on behalf of the Irish Rare Birds Committee (IRBC) – a group operating under the auspices of BirdWatch Ireland that is responsible for maintaining a list of the birds recorded in the Republic of Ireland, along with “at sea” records. The Irish Ringing Report 2021, which summarises birds ringed and caught in Ireland in 2021, is also included in the latest Irish Birds. There were many unusual discoveries, including a Kingfisher found in Tallaght which was previously sighted in East Sussex earlier in the year. Such long-distance movements of Kingfishers, especially overseas, are rare. There are also numerous examples of birds that reached a high age, including a Great Tit that was just one month shy of the British Trust for Ornithology (BTO) longevity record of 10 years 5 months and 18 days when it was re-trapped in Edenderry in 2021.
As the number one ornithological journal in Ireland, Irish Birds is a necessity for all serious birdwatchers and scientists working in the Irish conservation sector. The 45th edition of Irish Birds is now available from the BirdWatch Ireland shop, both online and in Kilcoole. Should you choose to support BirdWatch Ireland as a key member, you will receive a copy in addition to three copies of our membership magazine, Wings, every year.
Also, for those seeking previous issues, we have plenty of back issues of Irish Birds available at a reduced price. Whether you are keen to complete a collection or simply have a particular interest in a certain year or study, you can contact us to find out more about purchasing back issues.
BirdWatch Ireland expresses disappointment at outcome of Open Seasons Order review
BirdWatch Ireland acknowledges publication of changes to the Open Seasons Order by Minister Noonan for the coming season.
The removal of four duck species – Scaup, Pochard, Goldeneye and Pintail – due to severe declines in their populations shows some progress by the Minister to address the vulnerable status of these species. However, BirdWatch Ireland is disappointed that two additional species that we recommended for removal – Shoveler and Golden Plover – remain on the list though the science clearly shows declines in those populations also.
No rationale has been provided as to why these species remain on the list. The information provided announcing the decision is inadequate and lacking detail. The most severe impacts to waterbirds and wading birds that are on the Open Seasons Order relate to habitat loss and degradation, pollution, disturbance and climate change. However, every pressure and threat must be addressed considering the dire conservation status of many of the species that are huntable in Ireland. We hope that hunting organisations will support this decision and we also hope that government will assist hunting organisations to be able to contribute to data collection in Ireland.
Earlier this year, BirdWatch Ireland called for six of the 21 bird species currently permitted to be hunted under the Open Seasons Order to be removed from the list, a suggestion underpinned by the robust scientific evidence of their ongoing declines in Ireland. We also urged for more analysis to be undertaken by the National Parks and Wildlife Service (NPWS) to determine how best to proceed in relation to nine of the other species listed. These proposals were some of many made as part of our submission to the public consultation on the review of the Open Seasons Order for Birds.
