Using gland regions on their heads, warthogs mark poles and other objects for self-orientation. Males often mark during the mating season. The male also sprays urine when searching for and inspecting sleeping cavities.

The arousal behavior of the warthog is shown. Also explained is the muzzle fight between boars and females.

Short film about the movement patterns of protozoa

Experiments on the crystallization of various inorganic substances: crystallization from solution, crystallization from melt and vapour phase, mixed crystal formation, oriented growth, change from a metastable into a stable phase.

Short film on the mating behaviour of donkeys

The film shows birds and mammals of Spitzbergen: The snow bunting, Phalaropus fulicarius, Stercorarius parasiticus, the red throated loon, the arctic gull, the puffin, the black guillemot, the loon and the common guillemot are photographed at the hatching place. In addition reindeer, arctic foxes and musk oxen are shown. The voices of seven kinds of animals are heard.

Bonobos show a particularly pronounced sexual activity and an extraordinarily broad spectrum of sexual contacts for primates. These also extend to non-reproductive life phases and partner combinations. For example, homosexual contacts and sexual contacts between young animals or with adults are frequent, and females are ready to mate throughout the menstrual cycle. Bonobos use sexual contacts not only for reproductive purposes, but also in the context of social conflicts, where they have a clear tension-reducing or peacemaking function.

The film shows the spatial distribution and the behaviour of the Mediterranean demoiselle Calopteryx haemorrhoidalis on typical reproduction waters. The great importance of suitable perches becomes obvious. These perches, e. g. single rush stems, are used by immature, hunting individuals as well as by reproductive males that are controlling territories from these sites. The latter chase all other individuals, the result being a spatial segregation between immature and reproductive specimens during the day. Typical behaviour, such as threatening, courting, copulation, and oviposition is shown in different film speeds.

Gliding flight, soaring flight and flapping flight are presented as basic types of bird flight. The development of lift and propulsion are explained in the animation. Special features of shaking flight, take-off and landing are shown for different types of birds.

The Entlebuch is a rural pre-alpine area of Central Switzerland, known for its backwardness and isolation. This film deals with the contemporary life of the inhabitants of the region, between tradition and modernity. The protagonists' accounts of their own lives show the wide range of attitudes and offer insight into the valley's regional identity.

During the ewing-period the shepherd has to take especially care of the flocks. He has to assist the ewes in ewing, to control the feeding of the lambs, and to switch orphaned and abandoned lambs to ewes that have lost their lamb. This is still done by the traditional method of skinning: The dead lamb's skin is slipped on the abandoned lamb to deceive the mother ewe. At this time the shepherd must also warm newly-born, supercooled lambs inside the house and feed them artificially.

Calopteryx cornelia only occurs in one color morph and shows the typical dragonfly behavior. Species of the genus Mnais form different color morphs. Males with intensely colored wings are dominant over males with hyaline wings.

A portrait of the German city of Ulm and it's social activities, fassades, court building. Also about the role of the district court during National Socialism.

Documentary on how the osprey catches its prey. The film shows the search for prey, the launch maneuvers, take-off maneuvers and the fights with the fish.

Short film about the life cycle of a moon jellyfish

On display are the movement structures of Heliozoa, the expulsion of food remains, plasmogamy, separation and temporary bridging, "phobia".

Before shearing, done with electric devices and hand shears, lambs are separated from the flock. The lambs are not yet shorn but dipped in a disinfectant, parasiticidal liquid prescribed by law. For the auction, held in autumn, the sheep for sale are loaded on special trucks and transported from the pasture to the public sale.

The film documents the tobacco season of 1993/94 from the planting of the tobacco through the harvest and sale until the sowing for the next season - using some small planters from the villages around Schwedt on the Oder and a large farm, the former Agricultural Co-operative in Vierraden in an exemplary manner. It describes the transformation in the technical and agricultural fields. Different planters and representatives of the Tobacco Grower's Association discuss the situation of tobacco planting in the GDR compared to current conditions and answer questions on their self-organisation and on the future of tobacco cultivation in the Uckermark.

Zebra finches and Japanese gulls are shown, as well as the rearing of young zebra finches by Japanese gulls. Despite considerable differences in the appearance of the nestlings, the gulls provide their own and the foreign young with food equally. The male zebra finches raised by the foreign species later direct their courtship behavior exclusively towards the stepparent species, i.e. they are sexually imprinted on the foreign species.

The courtship behavior of Great Bustards is studied. The male Great Bustard is considerably larger than the female. This impression is reinforced during courtship when the male dances in front of the female, showing the light undersides of its wings and inflating its throat pouch.
