Following the mysterious death of eleven penguins at Dublin Zoo visitors try to catch a glimpse of Percy, the last surviving penguin.

Two weeks ago in the space of 24 hours, a mystery illness killed 11 of Dublin Zoo's 12 jackass penguins. The penguins were between four and 17 years old. Some had come from Amsterdam and Britain; others were bred at Dublin Zoo. All of the birds were in good health up to the time of their deaths.

Two weeks on it’s still a mystery as to what happened to the penguins.

Percy, the sole surviving penguin hides from view among the rocks in his enclosure, unwilling to come out. Many visitors glimpsing the lone penguin are moved by his plight,

Ah the poor thing.

Initial post-mortem examinations on the 11 penguins failed to reveal their cause of death. It is speculated paint used in their enclosure may have been toxic. However this is unlikely as the paint had been used before without any ill effect.

In November 1997 a second post-mortem revealed the penguins most likely died from a serious form of food poisoning present in the fish fed to them.
