Falcon was in avengers 3 Age of Ultron, but he died in agents of shield at the end of last season.
Haven’t seen the episode yet. You should really tag this with a spoiler warning.
Different people. Similar from a physical feature perspective but not playing the same character and not the same person.
Nobody noticed because you’re confusing two completely different actors playing two completely different characters.
wow, never knew they were 2 different people…they look very similar…almost like twins…As for not seeing that episode, that was last season, not last week. It aired a year ago, so if you think you need a spoiler for that, when do you not need a spoiler? Jamie, I could do without the sarcasm. A simple, they are 2 different people would have sufficed. As a moderator, you should be above this kind of thing…but I guess you are infallible and can’t understand how us little people are allowed to breathe the same air as you.
did falcon throw birds at people when he does bird strike 
That isn’t sarcasm. That is a literal statement. “They are two different people”.
If by birds you mean .22 automatic pistols, then… yes?
Movie falcon doesn’t have a Redwing, or any superpowers other than “really cool military hardware”.
Considering the post above Jamie’s addressed the question politely and completely, his post did read as needless snark.
