Aircraft; Airspace Structure; Procedure
When in decent into LGA we were instructed to descend from 5000 to 4000 ft. fly over the Statue of Liberty and fly up the Hudson for the arrival. We complied and as we were about 4500 ft.; and just prior to overflying the Statue of Liberty; I looked down and saw what looked to be a drone just below us maybe 300-500 feet below. I saw what to be an X type drone white with black propellers and green and red blinking lights. I reported to ATC about the drone incident asked if the Captain had seen it; which he did not; and we did not need to take any evasive action for the drone. We continued in to the airport normally and had no other incidents. After landing; I contacted NYC TRACON and told him what I witnessed and the information of what he wanted to know.
B-737 First Officer reported encountering a drone while on vectors for landing at La Guardia.
