2016 'Beaver' by the German Professional Association of Zoo Keepers
The exhibit for Humboldt penguins replaces a former penguin enclosure in the same area that was no longer suitable for keeping and presenting this species. The new exhibit is located in front of the zoo’s rainforest hall and fits its South America theme.
The walk-through exhibit is covered by a net. The outer exhibit barrier is made of small grid woven wire mesh. The back wall is designed with artificial rock resembling the rock structures in the penguins’ natural habitat. Nesting holes for the penguins and Inca terns are built in the rocks. Large natural stones are placed in the exhibit and in the visitor area.
The front of the exhibit is dominated by the planted land surface and includes a stream. On the right of the visitor path, there are the nesting holes in the back wall. Further back, the water basin extends along the left side of the path up to the fence with built-in underwater viewing windows.
The overall enclosure is about 1000m², thereof 250m² water surface and 750m² of land area that the visitors can partially access.
Space allocation in square meters:

The exhibit was funded by the Friends of the Zoo Association. One third of the construction process was carried out by zoo staff.
FEATURES DEDICATED TO ANIMALS:
A 250m² large water basin with varying depths and several stream jets is available for the penguins. The complete land area including the visitor path can be accessed by the animals. The birds can swim or dive underneath the visitor bridge to reach their nesting holes on the other side of the path. The wooden nesting boxes are integrated in the rock wall so that they are well-ventilated and dry quickly. Nesting places for the terns are mounted higher on the wall so the penguins cannot reach them. They can also breed undisturbed in the indoor area.
FEATURES DEDICATED TO KEEPERS:
The keepers can open the nesting boxes from outside the exhibit. A ladder is needed for the elevated nests of the terns.
FEATURES DEDICATED TO VISITORS:
The visitors can enter the exhibit through a double door system. The path has guide ropes on both sides and leads along the artificial rock wall across the penguins’ land area so the animals can be observed from a close distance. A wooden bridge crosses the water basin. In front of the South America house, there is a sheltered area with a bench. Here, visitors also have views into a large aquarium inside the house.
The visitor area is lowered in front of a large panorama window by two stairs. From this place outside the aviary, the birds can be seen swimming.
The species kept in the exhibit are presented on individual signs. Large panels give information on the penguins’ adaptions to their aquatic lifestyle, their role in the marine food web, the breeding behavior, the conservation efforts for the Humboldt penguin and the function of the reed filtration system. The visitors can get to know the penguins of the world in size comparison based on models of the different species.
To give the animals times of quiet, the exhibit can only be entered by visitors between 11 am and 4 pm.
The water basin is cleaned from large algae by voluntary divers once a week (particularly during summer).
Water jets 20 to 40 cm below the water surface are activated several times during the day. They channel surface particles to the spillway and suspended particles to the floor drain in the middle of the pool. The floor drain can be manually opened by the keepers. During long lasting low winter temperatures the jets prevent freezing of the water surface by swirling the water. The penguins like to swim with and against the flow that the jets create.
Krefeld zoo participates in the European conservation breeding programs for Humboldt penguin and Inca tern. The zoo also supports the Sphenisco organization – Save the Humboldt penguin.
The water from the penguin basin is ecologically cleaned by a reed filtration system next to the exit of the South America house and additionally disinfected by ozone.
