Here are lists of the birds and mammals I saw or heard on the trip. Other people saw some of the species listed as heard-only. I didn't include heard-only species that I've never seen before. Life birds are in blue bold and Peruvian endemics are marked with an (E).

Including heard-only birds, there are 301 species. Of these, 292 were seen and 101 were lifers.

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).
