Yep, it is the same, to me, as animals that use tools. And, there is nothing new or unusual about animals having learned behavior.
However, in this case, it isn't only about birds but fish or egg survival. Also, I do not believe in any animals husbandry.
I have actually experimented with this stuff. We went to a local flea market and bought a duck. Admittedly, it was one lousy duck and not a huge number of different kinds of ducks for proper sampling. We killed it and tried to get BG eggs to attach to either the feet or feathers. BTW, killing the duck was easy compared to scooping up and handling the BG eggs. Anyway, the eggs didn't stick to either the feet or feathers. I guess the argument could be made that I'm not as good as Mama Nature when it comes to mixing eggs with fish and feathers. And I guess some could say that fish eggs only attach to live ducks. But, I don't know of anyone else who is dumb enough to try it and I doubt that I'll try it again. Heck, even if they had stuck, the odds get pretty skinny regarding the eggs actually hatching and becoming fish.
