At each point along the journey she will spend time with the people who live along the swans’ path, who may have clues as to the decline of the swan population.
Over the last two decades, the number of Bewick’s swans making the journey back across northern Europe has almost halved. Researchers have identified several dangers that the swans face, but the exact reasons behind their decline remain a mystery.
Sacha Dench said: “I’m so excited to finally be off. I’ve been planning this expedition for two years. It’s going to be a real adventure. I love flying and I’m fascinated by wildlife. I’m filming the whole trip and I can’t wait to share my swan’s eye view with the world."
“But my biggest hope is that we gain a better understanding of what is going wrong for the Bewick’s swans. They each first make this long journey at just a few months old, and they return here to their birthplace every summer for the rest of their lives. It’s an extraordinary lifestyle, but sadly fewer and fewer are surviving.
“We’re doing all we can as conservationists to get to the bottom of this problem, but it’s not happening fast enough for the swans, so it’s time to get on the road and in the air, to see the places and meet the people that might hold the key to this mystery.”
Her progress is being tracked by satellite and you can follow her progress here.
And twice a week she will broadcast video diaries, detailing her progress and encounters with the swans and the people along the way.
She is also collecting signatures to show the level of support for helping the Bewick’s swans. Make every kilometre count. Sign the petition here.
