Kurze Mitteilungen

Summary

In forest of the Brasilian Amazon, the Black-eared Fairy (Heliothryx aurita) uses a gliding fall, similar to that movement presented by the fall of a dead leaf, when leaving the nest. This behaviour may protect adult or nest against forest hawk predators.

Zusammenfassung

Der KolibriHeliothryx aurita zeigt beim Verlassen des Nestes eine Flugweise, die einem herabfallenden Blatt sehr ähnlich ist. Wie beiH. barroti ist zu vermuten, daß die Imitation fallenden Laubes als Schutz vor Nesträubern zu interpretieren ist.
