Many fans of birds (avian dinosauurs) already knew about the American Blue Jay as being possessed of extraordinary cognitive feats such as you describe. Some readers may not know of the extensive research that has been conducted over just the last 20 years. Jays are members of the corvid family along with crows, ravens and magpies. The New Caldonian Crow is able to solve puzzles that 8 year old children can solve. And so can another bird family, the parrots - also known as psittacines or psittacaforms.
Your article is a wonderful addition to what is known about these special birds. Even though there are no parrots or crows in the same category (song birds).
