Bewick’s swans migrate but leave cygnet behind
February 2014: A Bewick’s swan cygnet appears to have abandoned by his parents at WWT Slimbridge Wetland Centre in Gloucestershire. Yesterday WWT researcher Julia Newth, who recognises the hundreds of swans in the flock by their individual face markings, saw that one family had acquired an additional youngster.
The lone cygnet has latched onto Slimbridge regulars Wooton and Stinchcombe and their four cygnets, but is spending much of its time calling in the hope of being reunited with its own parents.
Bewick’s swans migrate in large family groups and due to recent mild weather all but 10 of the Slimbridge flock have departed already.
Julia Newth said: “Occasionally, cygnets become separated from their parents during migration when there is perhaps bad weather, but it is rather more unusual to see such a separation before the journey has begun.
“We’re all waiting to see whether the parents return. If they don’t, and the cygnet leaves with its adopted family, we will call on our extensive network of swan researchers along the 2,500 mile journey to Russia to keep an eye out for them and check whether the lone cygnet manages to stay with them.”
Away from Slimbridge, where the swans are uniquely recorded by their facial markings, the swans are tracked by coded plastic rings on their legs. The lone cygnet has not been ringed but its adopted parents, Wooton and Stinchcombe, have white leg rings with the codes BAU and BAS.
Along the 2,500 mile migration between Slimbridge and Arctic Russia, the swans rely heavily on a chain of wetland sites for opportunities to rest and feed.
The Bewick’s swan study at Slimbridge celebrated its 50th anniversary earlier this month. Its findings have opened up the social structure of Bewick’s swans’ lives, revealing their lifelong pairing and strong family bonds. The longest-running dynasty is known as the ‘gambling’ dynasty, after a young swan was ringed and named Casino in 1971. Over the years that she returned to WWT Slimbridge she brought back 32 cygnets, who in turn have brought back cygnets of their own. This winter, three generations of the family have stayed at WWT Slimbridge, bringing their own respective partners and families, making them one of the most dominant and successful dynasties in the flock.
The study has also revealed the occasional anomaly, such as in 2010 when a regular pair, Saruni and Sarindi, returned with different partners. It was only the second instance of a swan ‘divorce’ in the entire study of more than 4,000 pairs.

Power line research to reduce risks for tens of thousands of swans and geese
September 2013. The safety tens of thousands of swans and geese in the UK could be improved by new research into collisions with power lines, which started this week with the installation of more than 150 special bird diverters in Lancashire.
Power lines are most common cause of death for swans
Flying collisions are the most commonly recorded cause of death for swans, whose size means they have poor manoeuvrability in flight. Bird diverters are special attachments to the lines that help make them stand out to birds in flight.
For the first time, a partnership between Electricity North West, Lancaster University and the Wildfowl & Wetlands Trust (WWT), is studying the efficiency of different types of diverter, alongside agricultural, weather and landscape factors which affect birds’ flights. The study area around WWT Martin Mere in Lancashire is the winter home of 30,000 pink-footed geese and 2,500 whooper swans and has been identified as a sensitive area for collisions.
Dr Eileen Rees, Head of UK Waterbird Conservation for WWT, said: “Tens of thousands of migratory geese and swans make the UK’s wetlands their winter homes. Collisions with power lines are a major cause of death for them, so WWT is delighted to be working with Electricity North West to make Lancashire, and the UK as a whole, a safer place for them.
“Through this innovative partnership we aim to gather evidence for solutions that work in our modern landscape. As well as reducing the risk to swans and geese, the results of the study should help electricity suppliers throughout the UK provide their service with fewer unnecessary interruptions.”
Steve Cox, future network manager for Electricity North West, said: “We hope that the diverters and our subsequent research will go on to help birds and electricity customers across the UK.
“By working closely with WWT Martin Mere we discovered this was a sensitive section of the network as it was located in a known flight path and we are delighted to be able to help protect these wonderful birds.
“By limiting the chances of any collisions, the special diverters will also reduce any possible impact on customer power supplies.”
Dr Ian Hartley, a Senior Lecturer at the Lancaster Environment Centre at Lancaster University and a behavioural ecology expert, said: “This is a great opportunity and we are very pleased to be working with new partners on a project of such high calibre which is going to have a large impact on the area around where the geese and swans winter. One of our Master’s students will work on the project for a year and our input will be to add knowledge on the analysis and geographic information systems aspects.”
Throughout this winter, the study will closely observe the flight behaviour of geese and swans in and around WWT Martin Mere Wetland Centre. It will determine the importance of features, such as tree lines, the choice of crops and the wind direction on the birds’ choice of flight line and height.
