Of course all kinds of behavioural information gets passed on.

But perhaps your observation on what type of information is wrong. Perhaps you just don't put as much effort in your boo and waving as you used to!

I suggest you set up a similar long term experiment with lions; and let us know what happens when you boo and wave, or kick.

Pigeons are reknown for their exceptional avian IQs. They can be taught complex routines and stimuli responses, they can discriminate between individual members of their species, and it's been suggested before that they may be able to recognize themselves in a mirror. What they are perhaps best known for is their homing ability -- they can find their way back home over extended distances. This is not the same as the migratory instincts inherent in most birds, where they typically follow the same route each time at specific times of the year. It's also why pigeons have been used as nature's airborne courier in military history.

Learned behavior, however, is distinct from adaptations in an evolutionary context. It is not the same as pigeons having a genetic predisposition to ignoring your attempts at scaring them off. It's just as likely that the pigeons can somehow communicate the correct responses to "unlearned" pigeons through either body language or maybe even vocalization, or a combination of both. The "group dynamic" as it is understood by psychologists is very much alive in herd animals.
