I actually trained two pigeons to do this when I was in Grad school at Wichita State in the early 1970s.I was being supervised by Grant Kenyon(A muuray Sidman fan) and Robert Knapp who worked under Denny,Adelman,and Match at Michigan State. There are some video Clipps of pigeons doing all types of things in the Discovery Psychology Series in the learning segment,but I do not think it includes pin-pong(but I may be wrong). A search of the Grant Kenyon and Robert Knapp may be informative.
