Prior to the 2013 flooding, the zoo also had an area section dedicated to South American animals such as giant anteaters, red-bellied piranhas and various New World monkeys, as well as a number of birds including several species of macaw and two Andean condors. There also used to be an Australian animal portion, notorious for the Creatures of the Night exhibit, mostly consisting of various nocturnal animals such as bats. Also present were a number of kangaroos, emus, monitor lizards, and for a brief temporary time, koalas. Indian peafowl are allowed to venture around openly and freely across the zoo grounds, and are taken to an off-site facility for the winter months. Events Zoolights Zoolights is a Christmas lights festival held annually at the Calgary Zoo. It closes only on Christmas Day. The month-long, animal-themed show features more than one million lights and is the largest seasonal light show in western Canada. Recent controversy Following a series of high-profile incidents in 2008 and 2009, some commentators criticized the zoo's conduct and operations. Past incidents cited included: In January 2009, a two-year-old male Turkmenian markhor died after becoming entangled in an exhibit's play toy. In 2009, a knife was accidentally left in the western lowland gorilla enclosure. In September 2010, Calgary Zoo staff announced the overnight death of a second tiger cub born earlier in the week to a Siberian tiger. Zookeepers were not aware that Katja, the 10-year-old mother, was expecting, saying it is hard to detect pregnancy in tigers. Katja did not nurse her young. Zoo staff noticed her carrying the first kitten in her mouth, which is likely how it died. The zoo's veterinary team says both Siberian tiger cubs suffered similar head trauma. On 5 December 2009, an 18-month-old female capybara died after being crushed by a hydraulic door. A worker did not follow a long-standing procedure in operating the door. The zoo's director said all the incidents are unrelated. An independent review was solicited by the zoo in December 2009 and was conducted by the Canadian Association of Zoos and Aquariums. The report, released in 2010, spotlighted systemic problems. In response, the zoo developed a 36-point plan that included improving animal care procedures and collection planning, addressing staffing issues like training and structure, enhancing security systems and safety drills, and upgrading aging zoo infrastructure. Later that year, the zoo hired noted animal welfare specialist, Dr. Jake
