I am a Meteorologist in Trenton. We have "the bird guy' here.
They have about 8 falcons and they use them to keep the wild life away from the airfield.
They work for a company called Falcon Environmental (there is a web page)
It is cool to see the birds every day. They cages are next to my office.
If you have any questions let me know and I will ask one of the guys to email you back.
