Why are Monk Parakeets considered a “potentially dangerous species” in NJ?

Especially when on Wiki it says the following:

As pets

Monk Parakeets are highly intelligent, social birds. Those kept as pets routinely develop large vocabularies. They have been described as one of the top ten “talking” bird species, able to learn scores of words and phrases.[8] This species is considered especially adept at learning to “talk”, only the African Grey Parrot having a better reputation for doing so.

Doesn’t sound dangerous to me…

I guess NJ lawmakers are STILL smoking crack and having homosexual affairs.

Monk or Quaker parakeets are considered a pest because if they escape they become feral. They join existing wild flocks and cause a lot of damage to crops, electrical wires (telephone poles). Quaker parrots are banned in many states and in other states you may need a permit, to own or breed them. I live in NY and have a quaker. Breeders must have a permit to breed them (I believe). Check out this web site that focuses on the flocks in Brooklyn, NY.
