The behaviour of most animals has evolved in a communication network
environment, in which signals produced by senders are perceived by many
intended and unintended receivers. In this study, we tested whether the
corncrake (Crex crex), a nocturnal rail species with innate (non-learned)
calls, is able to eavesdrop on the interactions of conspecific males and
how this eavesdropping affects subsequent responses by the eavesdropper to
territorial intrusion. In the first step, simulated aggressive or neutral
interactions between male dyads were presented to a focal male. In the
second step, the calls of winning, losing or neutral males from the first
step were played within the territory of the focal male. We measured
behavioural and vocal responses of focal males. We found that corncrakes
eavesdropped on signal exchange between rivals. Males often began
responding to distant aggressive interactions during the eavesdropping
phase, and they responded strongly during the intrusion phase of the
experiments. The response was significantly weaker to playback of males
from neutral interactions than to those involved in aggressive
interactions, and we found no differences between the responses to Winners
and Losers entering a focal male territory.
Wojas et all_Corncrake eavesdroppingData was collected during three
seasons of field work (2013, 2014, 2015) in Upper Nurzec River Valley in
Northeast Poland. To create this data we used Avisoft SASLab Pro 5.2.x
(Avisoft Bioacoustics, Berlin, Germany), STATA v. 14.2 (StataCorp, College
Station, TX, USA) and IBM SPSS Statistics v. 24 (IBM Corp, Chicago, IL,
USA). The final version is created in Microsoft Excel file. Column heading
are describe in worksheet called ‘legend’.
