I am actually torn on this. Parrots are not domesticated, they are only a few generations at most out of the wild and still retain many of their natural tendencies and expectations of life. Hunger is what motivates wild parrots to forage and to move from place to place to seek food and I'm sure they don't always find a meal at all on any given day. I think they are severely overfed in domestic homes as most people give them a brimming full dish of food 2X a day (with food available 24/7) and allow them to eat as much as they want. I don't think this is any healthier or good for them mentally than one small meal a day that essentially leaves them starving into being motivated to train. I think there is a balance between feeding enough they are satisfied at the end of the meal, yet not allowing for them to just stuff their face all day long so they are still food motivated enough during the day to work for a little more (be it through foraging or trick training).
BTW, Kiwi's food is always portioned and removed after he's done eating (I do not believe in free feeding). He only has foraging and treats during the day, though he does get a AM and PM meal. There have been days I've left his dish in, yet he still seems to prefer to forage for his treats or train for them. It's a natural and normal thing for them to want to do, and many birds (given the opportunity) do seem to prefer working for their food. Of course, I still like to make sure he gets 2 'free' meals a day
, but his daytime snacking is always earned food. I don't find encouraging his natural behaviors, enticing him to be more active and stimulating him mentally to be a 'cruel' thing to do (when done within reason).
Ah, April, but your method and this trainer's method have enormous differences. What you are describing resembles more what Aquila outlined in her post, which is fine.
A meal is still provided at the 2 bookend portions of the day, with care taken not to overfeed. And while you're not free feeding, foraging opportunities are provided throughout the day. To me, that differs quite a bit from essentially setting up a system whereby a bird has to perform tricks for you in order to be fed more than one small meal in a day.
I do agree with you that most domesticated parrots are overfed. I actually don't free feed my birds, either. I don't have a problem with those who do, as I know many who do so successfully, but I have 2 ekkies who would eat themselves into feathery food comas if given the chance. So they get one meal in the morning, and one at night. The rest comes from treats during training or foraging. Their activity is maintained, leaving them healthy and fit, they don't live constantly on the razor's edge of starvation, and yet they do have that motivational edge they need for training between meals.
Believe me, though, both Jolly and Bixby are poster children for why the trainer's method would be tempting. For Bixby, I remember there was one night where we were all late getting home from somewhere, and for Jolly, it was actually yesterday when I woke up late for the morning feeding. Now, both birds love being on me. And I sometimes have to repeat myself when I want them to fly AWAY from me, say to a perch, their cage, or to another person.
WELL...
On these two, obviously rare, occasions, you should see how responsive they were while waiting for their food to get prepped! (I had a bowl of pomegranates on hand in both cases.) Forget repeating myself! Suddenly a wordless gesture in the general direction of the perch was enough to send them rapidly flying in response! Or spoken word without gesturing! Heck, in Bixby's case even a nod of my head was enough! Smh. Little boogers understand exactly what I want. Whether by word or gesture, together or separately.
This effect is the exact reason the trainer does what he does. I just dislike the idea of my birds acting out of a desperate NEED to eat, you know?
(I didn't mention Maya, btw, as she is admirably consistent. She's "me" motivated, and treats don't change that even when she's hungry. Hahaha! Such a sweet girl.)
