social norms idea: a way to apply this concept to pigeons.

though i am leaving behind the idea of 'PDA' I have taken inspiration from certain factors of pda to develop on in my fresh ideas- such as how we find deem certain behaviours in culture to be sociably acceptable and others we don't, (e.g. sometimes extreme cases of pda is not deemed sociably acceptable ) -social norms. in my group tutorial, my group suggested a way for me to develop my idea about pigeons is maybe to look at how pigeons don't have this problem of social norms or social acceptance.

conformity - unwritten rules about how to behave in a particular social group or culture.
therefore to not conform to social norms, you stand out, and are deemed not normal.

however how do we know pigeons don't have social norms?
we have a stereotypical view or what pigeons do, how they behave, which as deemed as normal- one idea i could develop on would be to observe/see pigeons in a different light, or create situation you would not expect a pigeon to be in- feel this idea could be quite interesting and humorous.

if this idea did not work focusing on pigeons, i think exploring human social norms will still be interesting. eg one idea of social norms- how it is deemed normal to take your clothes off to go in the shower, but to take your clothes off in the middle of the street is not.
