| POSSIBLE AVIAN FLU. What looks like a sickly immature bird is currently on the main footpath opposite the Fox and Hounds pub car park. As it may be infected with Avian Flu, DEFRA have been informed. Autopsy results from three swans collected by DEFRA last Thursday have yet to come back. Please do not touch it or go near it. Another immature on the lake also looks like it may be sick as well as an adult. BBOWT have also been informed. |
