Asymptomatic Carrier, created for 2003's Frieze Arts Fair NYC, flies over the abandoned North Brother Island in the East River. Wikipedia says "now a bird sanctuary, the island is currently abandoned and off-limits to the public… …from the 1980s through the early 2000s it supported one of the area’s largest nesting colonies of Black-crowned Night Heron. However as of 2011 this species has abandoned the island for unknown reasons."
