Patterns of call communication between group-housed zebra finches change during the breeding cycle.

Gill LF, Goymann W, Ter Maat A, Gahr M - Elife (2015)

Bottom Line: Using on-bird microphone transmitters, we recorded the vocalisations of individual zebra finches (Taeniopygia guttata) behaving freely in social groups, while females and males previously unknown to each other passed through different stages of the breeding cycle.As birds formed pairs and shifted their reproductive status, their call repertoire composition changed.Call-type combinations of vocal interactions changed within pairs and were associated with successful egg-laying, highlighting a potential fitness relevance of calling dynamics in communication systems.

ABSTRACT
Vocal signals such as calls play a crucial role for survival and successful reproduction, especially in group-living animals. However, call interactions and call dynamics within groups remain largely unexplored because their relation to relevant contexts or life-history stages could not be studied with individual-level resolution. Using on-bird microphone transmitters, we recorded the vocalisations of individual zebra finches (Taeniopygia guttata) behaving freely in social groups, while females and males previously unknown to each other passed through different stages of the breeding cycle. As birds formed pairs and shifted their reproductive status, their call repertoire composition changed. The recordings revealed that calls occurred non-randomly in fine-tuned vocal interactions and decreased within groups while pair-specific patterns emerged. Call-type combinations of vocal interactions changed within pairs and were associated with successful egg-laying, highlighting a potential fitness relevance of calling dynamics in communication systems.

Mentions: When housed together in social groups in large aviaries (Figure 1—figure supplement 1), female and male zebra finches that were equipped with individual on-bird microphones (Figure 1) (Video 1) and that were previously unknown to each other, formed pairs and started to breed after nesting material had been added (Figure 2). At the same time, the call repertoire (Figure 3) of individually recorded birds changed (Figure 4, Figure 4—figure supplement 1), and vocal interactions in the group became increasingly pair specific (Figure 5, Figure 5—figure supplement 1). In within-pair calling interactions, the combination of call types involved changed (Figure 5), and was related to successful egg-laying (Figure 6).10.7554/eLife.07770.003Figure 1.Position of on-bird microphones on freely behaving zebra finches.
