Species in Focus - Whooper Swan
Irish name: Eala Ghlórach
Scientific name: Cygnus cygnus
🎺 The Whooper Swan is a large, migratory waterfowl known for its loud, resonating trumpeting call. The Irish name Eala Ghlórach translates as “noisy swan”.
🗺️ Thousands of Whooper Swans arrive in Ireland in October and November. They winter on wetlands and lowland open farmland after nesting in Iceland over the summer.
💪 Their black bill features a prominent, wedge-shaped patch of yellow and their feathers are all white. Adults have a wingspan over 2metres, and typically weigh about 10kg , making them among the heaviest flying birds.
✈️ When migrating, the Whooper Swan usually flies at an altitude of 50–200 m, but sometimes considerably higher. A notable case involved a flock of about 30 migrating from Iceland to Ireland on 9 December 1967, detected by air traffic control radar west of Scotland, at 8,200 m altitude. An analysis of the weather at the time concluded the birds were making use of a northerly jet stream wind to cut their flying time on migration for the 1,100 km trip from Iceland to Ireland. It would have taken them just 7 hours to complete the journey. In doing so, they had to tolerate an ambient temperature of -48°C plus air pressure only one third of surface pressure!
🔭 The Whooper Swan is Amber listed by BirdWatch Ireland, meaning they are of medium conservation concern. Wintering populations are monitored through the annual Irish Wetland Bird Survey (I-WeBS) and a census is carried out every five years. Although there is some evidence that the numbers wintering in Ireland are going up due to an increase in the Icelandic population, they face ongoing threats from avian flu (H5N1) and habitat loss.
🤚The Whooper Swan is designated in the EU Bird’s Directive, which mandates special conservation measures. This fundamental environmental protection is now at risk of being weakened. See the EU-wide campaign for more information.
