The Maryland Zoo in Baltimore is a zoo located in Druid Hill Park in Baltimore, Maryland. It is accredited by the Association of Zoos and Aquariums . Home to over 2,000 animals, the zoo is generally considered to be the third oldest zoological park in the United States, having opened in 1876. In 2004, the zoo was struck by financial problems and was forced to reduce its collection size by closing parts of the zoo. The Main Valley was closed due to its age, being incapable of holding animals comfortably, and the Reptile House was closed. The reptiles, as well as gibbons and snow leopards were sent on loan to other zoos and aquariums. In 2008, the zoo was featured in America's Best Zoos 2008. read more
