Wicksteed Park bosses have said they will be looking at improving security after yobs slashed the netting of an aviary.
The damage was caused at the new Woolloomooloo walk-through aviary which opened just a few weeks ago at the Kettering park.
It comes after several other reports of problems at the popular park.
Alasdair McNee, managing director of Wicksteed Park, said: “We believe this incident happened on Friday night and it follows on from several reports of juvenile nuisance in the park and in the Barton Seagrave area.
“We have a CCTV camera in the vicinity of the aviary and are currently reviewing the footage as well as liaising with the police.
“At this stage we are unaware of any birds escaping.
“The aviary was protected by robust aviary netting which is very difficult to cut.
“However we are now looking to improve security to try and prevent further incidents.”
A spokesman for the park said some ball-bearings had been found in the aviary following the incident, but it was not clear where they had come from.
A post on Wicksteed Park’s Facebook page said: “This is mindless vandalism.
“Can you assist us please and report anything untoward.
“We are already experiencing a lot of minor issues with a group of teenagers but this another level of wanton stupidity.”
The park’s website says the aviary has about 60 colourful and free-flying birds inside the huge Australian-themed aviary including Diamond Doves, various types of finches, budgies and kakarikies.
