Avifauna are animals with an internal skeleton and two legs because the two other legs have adapted to become wings. These are, of course, birds.

The 'top down' search now moves to family level. If you are not comfortable with families of birds then why not try another way? You can search birds by size, by colour, by month, by habitat or by site. Just click the pic to see the range of options.
