Birds tagged in Jersey show pox signs
More than 130 birds caught in Jersey were found to have a potentially deadly form of avian flu, according to Durrell Wildlife Conservation Trust.
Glenn Young, from the trust, said 138 starlings caught and ringed at Trinity Manor were showing signs of avian pox.
The disease, which is spread by mosquitoes, can not be spread from bird to bird and it can not affect humans.
But it causes uncomfortable growths meaning it is difficult for birds to feed.
Mr Young wants people in Jersey to be on the look-out for the signs.
He said: "A lot of these birds like starlings and great tits will be seen on people's bird tables so people may see these problems.
"Usually they are warty like structures around the face, the eye and the bill and also on the legs."
