Since the last week in April, a Peregrine Falcon has been seen in the trees just east of the John Lynch Bridge (Rt. 18) along the Raritan in Johnson Park.  On one occasion there were two Peregrine Falcons in the trees. There is speculation that they may want to nest on the bridge, which is not unusual in an urban environment. In Jersey City they are known to nest on ledges of tall buildings. 

Peregrine feed on other birds. They will dive from above going about 200 mph and hit the prey with their talons. The impact is sufficient to kill the prey.
