Dynamic risk assessment: does a nearby breeding nest predator affect nest defence of its potential victim?
Original language description
There is growing evidence that birds are able to discriminate different types of nest intruders and adjust their nest defence behaviour according to intruder dangerousness and distance from the nest (the dynamic risk assessment hypothesis). Here, we tested whether birds' decisions about nest defence may additionally be affected by an increasing familiarity with a particular nest predator. We tested nest defence responses of great reed warblers Acrocephalus arundinaceu to a nest predator, the little bittern Ixobrychus minutus. Great reed warbler nests located close (B7 m) to synchronously breeding little bitterns were ''neighbour'', other nests were ''solitary''. Great reed warbler specific aggression towards a little bittern dummy was much lower (*5-times) at neighbour than solitary nests. In contrast, generalised responses to a control innocuous intruder (the turtle dove, Streptopelia turtur) were statistically identical at neighbour and solitary nests. These patterns are in line with
