Contrasting effects of egg size and appearance on egg recognition and rejection response by Oriental reed warblers
<p>Among potential hosts, the rejection of foreign eggs, which is a common and effective strategy to counter brood parasitism, depends on egg recognition. Multi-modal and multi-component recognition cues of brood parasitic eggs, which include both tactile (size, shape, and texture) and visual (size, shape, color, and maculation) cues, are potentially involved in the perception and discrimination of foreign eggs by hosts. An egg rejection experiment on the host with different types of model eggs can help to accurately assess the relative contribution of different components on egg recognition and constraints to rejection, in which videos can help identify the method of host rejection. Here, we assessed egg recognition and rejection responses by Oriental reed warblers (<i>Acrocephalus orientalis</i>), one of the most common hosts of common cuckoos (<i>Cuculus canorus</i>) which breed in eastern China. We designed six groups of model eggs for rejection experiments in which sensory cues included three grades of size and two categories of visual mimicry. Our experiments confirmed that the multi-modal traits, which included variation in size, were significant predictors of egg rejection: we detected significantly higher rejection rates of mimetic spotted model eggs than of non-mimetic blue eggs. However, large model eggs did not yield higher rejection rates and, instead, these were less likely to be rejected and more likely to be deserted compared with smaller eggs. Further video-recording data showed that there was no significant effect of egg size on the egg recognition rate (percentage of nests with evidence of egg-pecking). No evidence that the egg appearance had an effect on the method of egg rejection (ejection or nest desertion) was found. Only visual signals, such as color and maculation, contributed to the recognition of foreign eggs by Oriental reed warblers as recognizable clues, but not the egg size. The egg size had an impact on the type of egg rejection. It was less feasible for the warblers to eject large eggs and that is why they opted more often for desertion as the mean of model egg rejection. The significantly lower egg rejection rate of large eggs suggested that although some of them were recognized as foreign eggs, hosts failed to reject these eggs and finally the eggs were assumed to being accepted by the commonly-used nest-checking methods.</p>
