Figure 1From: The effect of hunger on the acoustic individuality in begging calls of a colonially breeding weaver birdDFAs on different hunger stages. Correct assignment rates for DFA on part 1, part 2 and both parts combined on calls from four different time intervals during the treatment (mean ± SE). Note that assignment rates increase with increasing hunger and the assignment rates for both parts together are almost twice as high as for single parts.Back to article page
