Animal BackgroundAnimal Background

Eurasian Lynx

Facts:

•Found in forested areas of northern Europe & Asia. •Average weight of 25 to 75 pounds. •Feed mainly on roe deer, chamois, rabbits, birds and rodents. Columbian Park Zoo is home to three Eurasian lynx: Koshka (pictured), Katya & Larisa.

ProgressProgress•Last semester’s conceptual design of a Lynx chaser track did not meet the Zoo’s criteria.

•Our alternatives included the possibility of a vibrating ball or laser light track.

•The zoo director recommended the vibrating ball for the lynx.

•Same focus as original project, but different approach towards goal.

balance when standing vertical.

The meerkat's eyes always have black patches surrounding them; these act like an equivalent to sunglasses and allow the animal to see very clearly on bright days, even when looking directly at the sun

The meerkat has small, black, crescent shaped ears that have the ability to close when digging to prevent sand entering.

One or more meerkats will stand sentry (lookout) while other members are foraging or playing in order to warn them of approaching dangers.
