This is about songbirds and how different groups performed best when matched to their genetic imprint but it's something that I have always supported when it comes to training birds to do tricks. We have often had people here asking how to make, say, a cockatiel, do a trick they saw a macaw doing (it was hopping like a rabbit) and I have argued that it's not logical or kind to even try it because hopping is something a macaw does naturally while it's completely unnatural to a cockatiel so trying to get it to do it is very stressful for the bird.
