The turkeycock is a large game bird of the poultry family, originally from North America, but brought to Europe in the 16th Century; by the end of our period, it had become a traditional part of English Christmas dinner. It’s a period charge, found as the crest of William Strickland, 1550, who’s credited with introducing the turkey to England [Guide 189], and as the allusive crest of Robert Cooke, 1556 [Bedingfeld 101].) The turkeycock is statant by default; it’s typically shown with its tail erect. See also cock.
