Birds
The list below is limited to those species which have been positively identified by the residents of the island. Many visitors claim to have seen some quite exotic birds but these have been omitted since confirmation is lacking.
We are always looking to improve our collection of pictures of birds. If you have taken a picture of one on Lismore, why not email it to us. Please let us know where and when you took it and (if you know it) what it is.
