population Lady Liuwa was the park's most prominent resident, and was the subject of a National Geographic documentary released in 2010. According to folklore, the lioness was a reincarnation of Mambeti, a member of the Lozi tribe who lived and died in the park, and a grandmother to several staff who were still working in the park, as of 2016. Lady Liuwa was first reported to be present in the park in 2002, and was said to have visited the woodlands often where Mambeti was buried. In 2008, after no lions returned to the park naturally, African Parks attempted to introduce a male lion, but he died during the relocation. Two other males were reintroduced in 2009. Both of them reportedly mated with Lady Liuwa, but she was infertile. The two male lions left Liuwa and made their way to Angola; one was killed by locals and the other, Nakawa, returned to the park on his own. Two lionesses were relocated from Kafue National Park to Liuwa in 2011; one of them was killed by trapping in 2012, and the other, Sepo, had to be returned to Liuwa after migrating out of the area. Sepo was captured, helicoptered back, and placed in a boma with Lady Liuwa. The pair bonded and were released after two months. After mating with Nakawa, Sepo gave birth to one male and two female cubs in December 2013. Nakawa was later killed, possibly from being poisoned. An unidentified lion was seen in the park in 2015. In September 2016, a collaborative project between African Parks, the Mushingashi Conservancy, the Zambia Carnivore Programme, and Zambia's Department of National Parks and Wildlife (DPNW) introduced another male lion to Liuwa Plain from Kafue National Park. The lion bonded with another in a boma for two months, and were then released. Lady Liuwa died of natural causes on August 9, 2017. Birds and reptiles 334 bird species, including various species of birds of prey, bustards, cranes (including grey crowned cranes and the endangered wattled crane), pelicans, pratincoles, and storks, have been recorded in Liuwa. Raptors include the bateleur, greater kestrel, martial eagle, palm-nut vulture, and Pel's fishing owl, as well as African fish eagles. Recorded water birds include the marabou, open-billed, saddle-billed, and yellow-billed stork, as well as the blacksmith lapwing, egrets (including the slaty egret), the grey heron, pygmy geese, the spur-winged goose, and the three-banded plover.
