Fifteen firefighters were involved in the dramatic rescue of three swans after they became trapped in disused Edinburgh sewage tanks.
Another bird died during the ordeal at Newbridge Sewerage Treatment Works near Ratho on 20 April.
The Scottish SPCA were called to the scene after being made aware that the swans had become trapped in the decommissioned tanks.
After teams arrived they learned that one of the swans had passed away, and knew it was crucial that they get the remaining birds out and to safety.
Scottish SPCA inspector Jennifer Surgeon said: “My colleagues, animal rescue officer Darren Malcolm and senior animal rescue officer Melissa Mailtand, and I tried to retrieve the swans but we were unable to reach them.

“We called the Scottish Fire and Rescue Service who were able to assist with the incident.
“In the end it took three fire appliances, around 15 fire fighters and five hours to get the swans out.
“Thankfully the swans were unharmed after their ordeal and we were able to transport them to a safe area for release.
“We’re really grateful to the Scottish Fire and Rescue Service for their assistance with this incident. Without them, we’d have had no way to reach the swans.”
The Scottish SPCA campaign #WildlifeWise aims to educate the public on when wild animals may require assistance and when it’s best to leave them alone.
