A pellet feeder for the birds.
A pellet feeder keeps pigeons pecking reliably and lets you run longer, cleaner lab sessions.
01Research in Context
What this study did
Millard (1979) built a small pellet machine for pigeon cages.
Birds pecked a disk and got a dry pellet instead of loose grain.
The rig let the session run longer without making a mess.
What they found
Pigeons kept pecking at the same steady rate with pellets or grain.
Longer sessions stayed clean because pellets do not scatter like seed.
How this fits with other research
Braam et al. (2008) later added a $25 infrared eye that checks every pellet drop.
Pair the two tools and you get both clean long sessions and proof the food really arrived.
Hulse (1960) did the same idea for rats with lick-triggered liquid.
Together these papers show one rule: match the feeder style to the animal and the study lasts longer with less waste.
Why it matters
If you run pigeon labs, swap your grain hopper for a pellet feeder. You will spend less time vacuuming seed hulls and more time collecting data. The birds work just as hard, so your reinforcement schedule stays intact.

03Original abstract
An alternative means of delivering food to pigeons in operant conditioning research is described. The feeder allows greater control of the amount of food delivered and reduces the amount of time necessary for the pigeon to collect the food. It is possible to extend the length of experimental sessions due to the reduction of food intake. Data obtained using the pellet feeder indicated that the control of responding is comparable to that observed with the standard grain-magazine feeder.
