More than 150 flight diverters are to be installed on overhead powerlines at Martin Mere Wetland Centre.
The devices will be clipped onto four or five different powerlines and the aim is to raise visibility for the 40,000 pink-footed geese and whooper swans which migrate to the area every year from Iceland.
A spokesman for Martin Mere said: “We have thousands of birds migrating here over the winter, and there are collisions with powerlines. This can kill or injure the large birds which can’t easily manoeuvre in flight.
“The strikes can also take out a line, resulting in power outages for the local community.”
He added: “We have worked with Electricty North West on this project and a new type of deflector will be in use on the powerlines that are most prone to collisions.
“We are also going to have a student with us from September to March, looking at a lot of data, including the weather patterns, our previous logs, and whether the deflectors are working.
“We expect that the geese will start appearing here from Iceland in mid to late September, so this is coming at just the right time.”
The work is being carried out on Thursday at the site in Fish Lane, Burscough.
