Die Entstehung der persönlichen Beziehungen zwischen Jungvogel und Eltern

Summary

During incubation and rearing of young, colonial breeding birds are safe-guarded from conspecific interference not only by special isolation of the breeding pairs, but also by particular behaviour patterns. In the guillemot (Uria a. aalge Pont.) the mean inter-brood distance is 0-50cm. Here there is no spacing-out, therefore the development of specific behaviour patterns is of special importance for the undisturbed raising of offspring. The members of one family are kept together by inter-individual auditory ties, which simultaneously isolate them from their cliff-ledge neighbours.

  1. The relationship between adult and young before hatching
    • a) Hatching activity
    • b) Influence of the chick in the egg on the parents
    • c) Influence of the parent on the chick in the egg
    • d) Experimental investigation of the learning capacity of the chick in the egg
    • e) Learning phases
  2. Relationship between adult and young after hatching
    • a) Behaviour of the chick towards the parents and stranger birds under "normal" conditions
    • b) Experimental evidence of the specific effect of parental calls on newly hatched young
    • c) Behaviour of "orphans" towards stranger birds
    • d) Experimental evidence of the learning capacity of chicks for new calls
  3. Capacity for differentiating auditory stimuli
  4. Learning of visual stimuli associated with food and shelter
  5. Effectiveness of visual vs auditory stimuli

Zusammenfassung

Durch Artgenossen unbeeinträchtigtes Brüten und Aufziehen der Jungen ist bei Koloniebrütern, außer durch örtliche Isolierung Brutpaare, auch durchbesondere Vergaltensweisen gesichert. Ausgesprochen eng beieinander brü Trottellummen (Uria a. aalge Pont.). Daher ist die Ausbildung besondere isolierund wirkender Verhaltensweisen für die Aufzucht bei dieser Art besonders wichtig. Vor allem durch individuelle Lautbeziehungen werden die Glieder einer Lummenfamilie zusammengehalten und zugleich von allen anderen Artgenossen auf demselben Gesimse getrennt.

In der vorliegenden Arbeit wurde untersucht, wie und wann das Küken seine
