The DEFRA Web Site has useful information and should be consulted if more detail is wanted. The following extract from their "Questions and Answers" page addresses some of the basic issues:

11. My dog found some dead birds. Does that mean it will get 'flu?

There is no evidence that any type of avian influenza (AI) has passed from avian species to dogs. So even in the unlikely event that the reported dead birds had died from AI, the risk to your dog would be extremely low. Cases of dog ‘flu have been recorded in the USA, but in this case the virus is believed to have originated from horse ‘flu.

12. Am I at risk from touching dead birds?

Wild birds can carry several diseases that are infectious to people. If dead birds are handled, it is important to wash your hands with soap and water as soon as possible. Avoid touching your face and certainly do not eat until you have washed your hands. Clean any soiling on clothing with soap and water.

13. What am I at risk from?

Although the risk of AI may be low, birds carry other respiratory infections. Birds can also carry infections which can cause gastrointestinal infections such as Salmonella and Campylobacter
