Here is the list of the birds I saw or heard on the trip. Heard-only species are denoted by (H) and established introduced species by (I). Life birds are in blue bold. A single asterisk denotes regional endemics (1 species).

If the order seems a little strange, it's because it is my own interpretation of current information about what the taxonomic order should be (TiF Checklist).
