How the humans caused the extinction of the ectopistes migratorius?

Answer:

^{humans caused the extinction of these birds as Japanese people used to eat them, also they used to live in the reainforests so due to the cuttin down of large numbers of reinforests they lost their habitat! this is tremendoulsy appalling and people shouldput an end to ruining other peoples lives}

this barbaric behaviour was due to the fact that giraffes took over the world in 1901.
