In Barrie's "Peter Pan in Kensington Gardens", birds have a far more prominent role on a proto-Neverland called the Birds' Island. On the island, the various birds speak bird-language, described as being related to fairy language which can be understood by young humans, who used to be birds. The birds are responsible for bringing human babies into the Mainland, whose human parents send folded paper boats along the serpentine "with 'boy' or 'girl' and 'thin' or 'fat' (and so on) written", indicating to the official birds which species to send back to transform into human children, who are described as having an "itch on their backs where their wings used to be" and that their warbles are fairy/bird talk.
