July 5th, 2012. This small structure is in the shape of a square, with 4 metal cages protruding from its corners. There are two black metal cages on each side of the building, with a walkway in between each of them so that visitors can enter the building and see the 4 indoor rooms of the primates. Each cage is an eyesore as it is about 20 ft. x 20 ft. x 20 ft. and there were colobus monkeys, ring-tailed lemurs, siamangs, squirrel monkeys and king vultures in this part of the zoo. The colobus monkeys, lemurs and siamangs have both an indoor and outdoor area while the squirrel monkeys are all indoors and the king vultures are left outside to battle the elements. The siamangs fared the worst as due to the large size of these apes I calculated that it would take one of them perhaps 4 small swings to cross its entire existence. Perhaps because there is nothing else to do the male and female have recently sired 3 offspring (in 2008, 2009 and 2011 all males) and seeing all 5 apes in the metal box was a little depressing and also somewhat surprising.
