tilapia. On April 9, 2020 (during lockdown from COVID-19), after weeks of anticipation, Mabel gave birth to Akobi, a male calf. His birth marked the first pygmy hippo born at the zoo in nearly thirty years. They also share their enclosure with Wolf's mona monkeys. Throughout the walking paths, visitors can also see West African slender-snouted crocodiles, different species of turtle, snake, lizards, and various African freshwater fish; these different animals live in a series of densely-planted paludarium- and riparium-style exhibits, complete with thick glass panels for close-up animal encounters. In smaller vivarium and terrarium exhibits, other reptiles such as pancake tortoises, Gaboon vipers, puff adders and Schneider's skinks can be seen. Monkey Trails utilized a newer concept for the displaying of arboreal animals; by making the exhibits two storeys high, with stairs, walkways and elevators for access, the habits of animals can be observed from ground level as well as from the treetops. Some of the horticultural highlights of Monkey Trails include several massive Banyan fig (Ficus) trees (viewable in public areas as well as in animal exhibits), cycads, and a bog garden with Sarracenia, Drosera, Venus flytraps and other carnivorous plants. Owens Aviary The Owens Aviary contains about 200 individual tropical birds from around 45 species, mainly from Australasia, Oceania and Papua New Guinea. The aviary is built onto the side of an approx. 60' high canyon wall, being accessible via an entry/exit at the uppermost level and another at the lower end of the aviary (essentially the canyon floor). The walkway inside the aviary connects these entryways as it ascends and descends with the natural slope. The naturally steep location proves to be perfect for the exhibit's waterfall, which cascades downhill through the aviary before splashing down into a large pond. The ambient white noise of the waterfall is quite noticeable, but relaxing and tranquil, rather than very loud. The waterfall churns up mist, and a cool steam fills the aviary with ambient humidity; additionally, the outside of the structure is painted a dark green color, which helps to block any excess sunlight from penetrating inside. This further gives visitors the feeling of walking through a lush, dense jungle. The entire aviary is lushly landscaped and thick with palms, ficus, Araceae species (such as Monstera deliciosa and Thaumatophyllum), Clivia sp., ferns and many more varieties. The varied collection of bird life includes the Chinese hwamei, eclectus parrot,
