The following changes were proposed by the South American Classification Committee.
1) To treat C. viridipennis (Amazonian Swift) as conspecific with C. chapmani (Chapman’s Swift). C. viridipennis is the form known to occur in Peru. The two forms are now known as Chapman’s Swift.
Visit species account: Chapman’s Swift (Chaetura chapmani).
2) To recognize the new genus Cryptopezus for “Hylopezus nattereri” and transfer Hylopezus berlepschi, Hylopezus fulviventris, and Hylopezus dives to Myrmothera. Hylopezus dives and H. nattereri do not occur in Peru.
3) To merge the storm-petrel genus Oceanodroma into Hydrobates.

4) To establish English names for Turdus nigriceps and Turdus subalaris. The new name of Turdus nigriceps is Andean Slaty Thrush. T. subalaris does not occurs in Peru.
Visit species account: Andean Slaty Thrush (Turdus nigriceps).
5) To establish an English name to the previously split Catharus dryas and Catharus macualatus. The new name of Catharus maculatus is Speckled Nightingale-Thrush Peru. C. dryas does not occur in Peru.
Visit this species account: Speckled Nightingale-Thrush (Catharus maculatus).
6) To split Sclerurus mexicanus into four separate species. Recognize S. obscurior as a species. Other splits are still under review. The English name is South American Leaftosser.
