Golden-headed Lion Tamarin
With St. Patrick’s Day just around the corner, animals—and their keepers—at the Smithsonian's National Zoological Park’s Small Mammal House got into the holiday spirit. Keepers created animal-enrichment activities and objects full of treats for many of the small mammals. These enrichment activities provide physical and mental stimulation for the animals that give them opportunities to use their natural abilities and behaviors.
