Abstract:In the present paper, an example of the communal use of one and the same nest by two "pairs" of the Bengalee, Lonchura striata var. domestica, was described. There was no marked aggressiveness between the pairs. Six eggs laid by the two females were indiscriminately incubated. The eggs did not hatch, but a nestling inserted as replacement for the eggs was normally cared for by every member of the four. Shortly speaking, these birds performed all activities including nest building, incubation, and brooding as an individual of a flock consisting of four birds, rather than as a member of a pair. The availability of only one ready-made nest in the cage was considered one of the most important causes of this curious outcome, in combination with the gentle temperament of the species in general. /// Die vorliegende Arbeit beschreibt, wie zwei Bengali-Pärchen (Lonchura striata var. domestica) dasselbe Nest benützten. Es gab keinerlei auffallenden Unfrieden zwischen den beiden Paaren. Alle vier Vögel brüteten normal und unterschiedslos auf den von den beiden Weibchen gelegten 6 Eiern. Die Eier schlüpften nicht, aber ein untergeschobener Nestling wurde von allen vieren normal gefüttert und gehudert. Kurz, sie taten alles, Nestbau, Brüten und Brutpflege, nicht als ob sie zwei Paare wären, sondern wie Schwarmgenossen. Ausser der ungewöhnlichen Verträglichkeit dieser Art sprach vielleicht die Tatsache mit, dass nur ein einziges Korbnest im Käfig vorhanden war.
