I was thinking about cats, because they fit 2 out of 3 criteria: some people can’t stop sharing cat videos on social networks, and of course birds are afraid of cats. But cats usually don’t kill people, only give them toxoplasmosis.
A possible explanation is that our world happens in the future long after the depicted Bird Box events; the toxoplasmosis originally drove people to suicide, but now we have adapted to it.
