Kittiwakes: RSPB in netting call over 'heartbreaking' video
The RSPB has called for netting on buildings to be taken down because it is stopping endangered birds from nesting.
Video posted on Twitter showed a kittiwake trying but failing to reach ledges in Lowestoft, Suffolk. A dead bird was later found trapped there.
In the tweet,, external the RSPB said: "Heartbreaking to see kittiwakes find their home nesting sites blocked by nets."
Two of the building's occupants have pledged to take action.
