Yes, the pigeons are first trained to approach and eat from the feeder. They
must also be trained to peck the keys, either by differential reinforcement
of successive approximations, or by so-called "autoshaping." BTW, you are
right about pigeons; they "move away" from the feeder if you simply start
engaging it. I usually pile up grain in the aperture (with the feeder in the
"up" position) so it can be seen from anywhwere in the chamber (and the
birds, of course, are food-restricted). The birds are then allowed to eat
for a considerable amount of time (10-15 s) and the feeder is quickly
disengaged then engaged. Usually the feeder returns to the up position
before all the extra grain runs out and the process is repeated. Sometimes
you still get pigeons that are "hopper-shy," but it is relatively rare.
