 Pies in the 1400s included birds, as song birds at the time were a delicacy and protected by Royal Law.At the coronation of eight-year-old English King Henry VI (1422–1461) in 1429, "Partrich" and "Pecok enhakill" were served, alleged by some modern writers to consist of cooked peacock mounted in its skin on a peacock-filled pie.The expressions "eat crow" and "four and 20 blackbirds" are sayings from the era when crow and blackbirds were eaten in pies.
