A suspected case of bird flu has been reported at the Isle of Wight's RSPCA Centre.
It means the Godshill branch has had to close to all wild bird admissions as per Government guidance.
One bird, which had been displaying symptoms, was put in isolation.
After obtaining professional veterinary advice and advice from Animal and Plant Health Agency (APHA) and the Department for Environment, Food and Rural Affairs (DEFRA), a decision was taken to put the bird to sleep.
A statement from the centre reads:
"This one case, although unconfirmed, has had a significant impact on our entire animal centre and now requires the temporary closure of our facility for a few days while we complete a full deep clean of our isolation areas and monitor other birds in our care for any signs/symptoms.
"We recognise that it is extremely upsetting for all involved and for the public. These actions are to protect other birds in our care, and also humans and other mammals as there is a risk to all.
"In addition, branches and centres in the south coast (from Thames Estuary to the Isle of Wight) have received national guidance not to take in gulls from the south coast area due to the high zoonosis risk.
"This advice also urges all wild bird rehabilitators to liaise with their local vets which is critical, as sadly some seabirds may be unable to be admitted into care. Guidance is that wildlife centres without proper facilities and high levels of personal protective equipment for staff and volunteers should absolutely not be taking in these birds due to the high zoonosis risk."
RSPCA Isle of Wight says it hopes to re-open for admissions as soon as its isolation intake area, and birds, are given the all-clear.
