Corvids include crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers.
I can testify that blue jays will remember stuff for a very only time.
Our cat caught and ate a blue jay fledgling. For 4 years the parent bluejays dive bombed anyone coming into our yard and inflicted cuts and bites on several.
Some Blue Jays can even remember winning the World Series in 1993.
The Blue Jays had the chance to become only the third club ever to win three World Series in a row (besides the Yankees and the Athletics) but were deprived of a chance because of the 1994 baseball strike. They have never appeared in another World Series.
