Belvidere’s Summerfield Zoo has added an endangered monkey that is smaller than your hand.

Zoo Director Rick Anderson said in a statement announcing the arrival that, “Cotton-Top Tamarins are among the most endangered primate species in the world.  They are listed as a critically endangered species due to deforestation in their native home of Colombia, South America.  It is estimated there are only 1000-5000 wild cotton-top tamarin monkeys  remaining in the world.  We are thrilled to be adding a female to the zoo, as we already have a male cotton-top, and hope to start a breeding program.”

The tamarin monkey weighs only between 1 and 2 pounds, and are named ‘Cotton-top’ for the white hair that sits atop their head.  It will be available to the public for viewing Saturday, June 25 and Sunday, June 26, 2016 during the zoo’s animal encounter presentations.

Summerfield Zoo is open Saturdays from 10AM to 5PM and Sundays from 11AM to 4PM. Admission is $9 per adult, $7 per senior, and $5 per child.  For more information go to
