A further video posted by this person shows a single silvery pigeon with a larger group of pied imperial pigeons in a cage, potentially the same bird as in 1D (see Suppl. material 1–4) E screenshot of a video posted in December 2021 showing a single silvery pigeon with a group of green imperial pigeons and three pied imperial pigeons in a cage in Bintan island posted by the same person as in 1C but seem to be in a different setting (see Suppl. material 1–4).
