The Cuan Wildlife Center is keen to rethink the netting put in place at the Castle Foregate railway bridge in Shrewsbury earlier this year.
The center says the mesh, which was introduced in an attempt to reduce the amount of pigeon droppings on the sidewalk below, poses serious welfare concerns to the birds that are trapped.
Bethany Robinson, senior wildlife assistant at Cuan Wildlife Center, said a bird had been trapped in the net for three weeks.
She said they had footage of his mother trying to feed him through the net, while others rescued were “completely emaciated”, with 10 birds dead.
She called on Network Rail to remove the wire mesh, cover the underside of the bridge and create a dovecote nearby in an effort to give the birds a new “home”.
The issue of excreta under the bridge has been a significant issue, creating a dangerous roadway for the public and leading to the use of the net.
Ms Robinson said she believed setting up a dovecote would be an effective, albeit expensive, solution.
She said: “We would like the net to be completely removed. I know it would cost a lot of money, but it costs a lot of money if they have to keep closing the road and saving the pigeons every time they are. stuck.
“We would love to see them come aboard completely below deck so that no birds can get in at all and then return home.”
“Pigeons are homing birds, they’ve been perching under there for years, they see it as their home, even though that fence is there, they’re still trying to get in.
“It has worked in other areas where they make a dovecote and the birds are fed there.
“It would be expensive, but every time they have to go up there they have to get permission to close the road, then use a lifting platform to get up and retrieve the bird and fill in the gaps in the net.”
Ms Robinson said the company has shown it cares about birds with its efforts to take over the original project.
She said: “They put a lot of emphasis on making sure the birds are looked after, but they expected this plan to work and sadly it didn’t.”
In a statement, Network Rail said it had been made aware of fears that some pigeons would find their way inside the wire mesh and get stuck.
He said he regularly took care of releasing the trapped birds and added: “We take animal welfare very seriously and will do whatever it takes to resolve this issue as quickly and as possible. surely possible. “
