Northumberland Zoo says goodbye to Red the Hereford bullock aged 12

Red, who arrived at the zoo in February 2014, died at the age of 12 after a period of declining health. Keepers said he had been struggling with arthritis, which had increasingly affected his mobility in recent months.

A spokesman for Northumberland Zoo said: "Today we said goodbye to one of our longest lived residents here at the Zoo.

"He lived a great life at the zoo, being loved by so many.

"Peaches, our Highland Cow, was particularly fond of him and we will be monitoring her closely and giving her lots of love over the coming days."

Northumberland Zoo invited the public to share their memories of Red on social media.

Alongside their tribute, the zoo shared a photo of Red as a calf with Brian, the Zoo Director, taken in February 2014.
