Abattis de gibier à plume is a somewhat tortologous expression. These are the cheaper edible internal organs, including the gizzard, a muscular organ which acts as second stomach, heart and neck. Abatis do not include the liver, crest and kidneys, which are used in haute cuisine. Abatis alone means the giblets of a bird, but this does define it as being of game birds rather than domesticated poultry.
