North and South Brother Islands, East River
North and South Brother Islands are a pair of small islands in New York City's East River, situated between the Bronx and Riker's Island. North Brother Island was once the site of a hospital, but is now uninhabited and designated as a bird sanctuary. It measures approximately 400 m by 250 m. South Brother Island is 7 acres (28,000 m2) in size. It is uninhabited and designated as a wildlife sanctuary. Until 1964, South Brother Island was part of Queens County, but it is now part of Bronx County. It had long been privately owned, but was purchased by the city in 2007. Together, the two Brother Islands, North and South, have a land area of 81,423 square meters, or 20.12 acres (81,400 m2).
North Brother Island
The North island was uninhabited until 1885, when Riverside Hospital moved there from Blackwell's Island (now known as Roosevelt Island). Riverside Hospital was founded in the 1850s as the Smallpox Hospital to treat and isolate victims of that disease. Its mission eventually expanded to other quarantinable diseases.
The island was the site of the wreck of the General Slocum, a steamship which burned on June 15, 1904. Over 1,000 people died either from the fire on board the ship or from drowning before the ship was beached on the island's shores.
After World War II, the island housed war veterans who were students at local colleges, along with their families. After the nationwide housing shortage abated, the island was once again abandoned.
In the 1950s a center opened to treat adolescent drug addicts. The facility claimed to be the first to offer treatment, rehabilitation, and education facilities to young drug offenders. Heroin addicts were confined to this island and locked in a room until they were clean. Many of them believed they were being held against their will (as one person wrote on the wall). By the early 1960s widespread staff corruption and patient recidivism forced the facility to close.
Now a bird sanctuary, the island is currently abandoned and off-limits to the public. Most of the original hospitals' buildings still stand, but are heavily deteriorated and in danger of collapse. A dense forest conceals the ruined hospital buildings, and 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 2008 this species has abandoned the island for unknown reasons.
South Brother Island
Jacob Ruppert, a brewery magnate and early owner of the New York Yankees (responsible for bringing Babe Ruth to the New York Yankees from the Boston Red Sox), had a summer house on the island that burned down in 1909. No one has lived on the island since then. There are no structures extant.
Ruppert owned the Island until the late 1930s. In 1944 it was purchased by John Gerosa, president of the Metropolitan Roofing Supply Company, who intended to build a summer retreat for his workers on the island. This did not come to pass.
Hampton Scows paid property taxes every year but did not develop the island. In November 2007, the City of New York purchased the island for $2,000,000 using federal money. The city plans to preserve it as a wildlife sanctuary. It will be managed by the City's Parks Department and the Bronx Zoo.
The South island's dense brush supports a major nesting colony of several species of birds, notably Black-crowned Night Heron, Great Egret, Snowy Egret, and Double-crested Cormorant. New York City Audubon has monitored nesting colonies on the island for over twenty years.

"By contrast, South Brother and its bigger sibling, North Brother Island, have resisted such an invasion. North Brother's vegetation -- a jungle of thick brush, low trees and tangled bittersweet vines set among the ruins of a dozen quarantine and hospital buildings -- has produced a secure haven for the black-crowned night heron, the city's most populous heron species. More than 230 crude nests of sticks and twigs were counted there last June."
