Bird Land indoor tropical garden and aviary, Daejeon O-World (대전오월드 버드랜드)

Bird Land is one of the four zones of the O-World park, in Sajeong-dong (Jung-gu district), on the lower slopes of Bomunsan. The complex began as a zoo: after works started in November 1999 and ran for two years and five months, the "Daejeon Zoo" opened on 5 May 2002 with amusement rides. On 1 May 2009 the creation of the Flowerland garden gave the site the name O-World. Bird Land opened on 30 September 2016; the city of Daejeon's monthly magazine (May 2021) then gives the park a total area of 776,986 m², of which 608,283 m² is the zoo, while Korean Wikipedia states 783,897 m². The park is operated by the Daejeon Urban Corporation (대전도시공사).

The same magazine presents Bird Land as the largest indoor bird park in the country, open in any season and any weather. Korean Wikipedia notes that a greenhouse is among the facilities of Flowerland, opened in 2009. According to the official page, entering Bird Land carries no extra charge, and its hours, shorter than the park's, vary with the weather "for the protection of the animals".

The official plan, drawn in isometric view, lines up eight numbered markers: the hanging garden (행잉가든) near the entrance and ticket booth, the open-air emu enclosure (에뮤동산), the tropical garden (열대정원), a swan pond ("백조의 꿈"), the bird adventure zone (버드어드벤처존), the "exciting" bird zone (버드익사이팅존), the water lily garden (수련정원) and a block of facilities. The rooms appear joined to one another around a block of facilities.

Photographs published by the operator on its own site show roofs of translucent panels on a light frame above the hanging baskets and aviaries, a wall of many small panes in white frames behind the flamingo pool, artificial rockwork around the penguin pool, a rock wall pierced by dark openings in the hanging garden, where the official page mentions a tropical aquarium, and a painted rainforest backdrop in the parrot hall. The whole forms an indoor garden that can be visited in any weather.

On the plant side, the official page announces uncommon tropical plants, succulents and hanging baskets of trailing plants: the hanging garden combines these baskets with a rockwork setting, a tropical aquarium and a café area, and an official photograph also shows columnar and barrel cacti in a room with large glazed bays. The water lily garden presents tropical water lilies, lotus plants and tropical fish; the city's magazine describes it as an artificial pond where birds nest.

On the animal side, the route brings together Humboldt penguins, whose Peruvian and Chilean origin the city blog recalls, flamingos (유럽홍학), black-winged stilts (장다리물떼새), toco toucans, macaws (스칼렛매커우, 청금강앵무), grey parrots, lorikeets (오색청해앵무), conures (썬코뉴어, 몽크앵무) and cockatiels (왕관앵무). Outside, emus have their own enclosure. Talks on the birds' ecology accompany the feeding of the penguins and the parrots, according to the municipal blog of 2022.

The route follows the order of the official page: hanging garden at the entrance, tropical garden and penguins, adventure zone with flamingos and toucans, bird zone with the large parrots, water lily garden; the emu enclosure is outdoors. Entry is included in the O-World ticket at no extra charge, and the hall opens for shorter hours than the park, with extended opening on some evenings. The rules forbid pets, bicycles, balls and scooters, as well as jewellery and accessories the parrots might damage; they ask visitors to give only the food provided, not to handle the birds and to avoid sudden movements in the adventure zone.

The city blog advises checking the times of the talks in advance. The visit can be extended, within the same park, by the zoo, whose African safari is toured by bus, and by the Flowerland gardens, where the municipal magazine mentions a tulip festival in spring, a lily festival in summer and a chrysanthemum festival in autumn.
