The last dusky seaside sparrow died on Discovery Island, a nature reserve owned by Disney.
There were once thousands of dusky seaside sparrows living on the East Coast of Florida. When the bird started to die out due to pesticides and construction, conservationists at Walt Disney World’s nature reserve, Discovery Island, attempted to save the species through cross-breeding.
In 1987, Orange Band, the last known dusky seaside sparrow died in captivity, marking the end of the species.
