The park, which was home to 120 birds, has since reopened. The reopening is not a full return to normal: work to address the oil contamination is still under way, and a number of pens remain out of bounds. The 13 deaths were the result of vandalism of the home heating oil tank near the park. Oil from the damaged tank contaminated the birds and left residue in the pens that held them.
Once the oil leaves the pens, the birds will be moved back into them. Until then, those pens stay closed even as the rest of the park, formerly home to 120 birds, operates again after the deaths, the baths and the specialist treatment that followed the vandalism.
In a post on social media, The Waterfowl Pond confirmed that work was still under way to address the oil contamination.
Birds have returned to The Waterfowl Pond after the park reopened following vandalism at a nearby home heating oil tank that killed 13 birds. More than 20 birds were transported to the USPCA's headquarters for urgent specialist care following the incident.
The spill mattered because the oil reached the collection itself. The Waterfowl Pond said all of the birds, including geese, ducks and swans, needed to be bathed and treated because of the level of contamination they suffered. The same post said a number of pens remained out of bounds while that work continued. The BBC reported the post.
There is still some oil around the edges, the park said.
