Suspected avian botulism outbreak at Rye Harbour Nature Reserve
- Suspected avian botulism outbreak
We have sadly become aware of a number of dead birds at Rye Harbour Nature Reserve, with avian botulism suspected as the cause. Avian botulism is caused by a naturally occurring toxin that can appear in warmer weather. It poses a very low risk to people, but dogs can become seriously ill if they eat an infected bird or drink from contaminated water.
Recent hot and dry conditions have caused water levels to fall significantly, creating conditions in which the toxin can develop. Similar incidents have been reported in other areas of the UK this summer.
Part of the reserve is closed to visitors due to suspected outbreak of avian botulism.
Please follow on site signage.

Large numbers of birds may be affected and outbreaks like this can last for several weeks and may recur. Affected birds lose movement of their wings and legs, and are unable to walk or fly away.
Public events on the reserve have been put on hold for now and anyone booked on cancelled events has been contacted.
If you find a dead or infected bird, please report it to the DEFRA helpline: 0345 933 5577 We're monitoring the situation closely and will begin the process of removing dead birds. We will share further updates as the situation develop.
