“…Specifically, we observed 255 that zebra finches are biased to produce short-duration vocalizations as INs, approximately three times 256 before their songs, regardless of their tutoring experiences during development. Interestingly, INs are 257 also seen before the start of song in suboscine birds [13,15,17] where song is not learned and before 258 advertisement calls in other vertebrates that produce unlearned vocalizations including frogs [4] and 259 toadfish [5]. These data support our findings showing the presence of biological predispositions in IN 260 production even before learned vocalizations, like birdsong.…”

9Introductory gestures are present at the beginning of many animal displays. For example, lizards start 10 their head-bobbing displays with introductory push-ups and animal vocal displays begin with 11 introductory notes. Songbirds also begin their vocal displays by repeating introductory notes (INs) 12 before producing their learned song and these INs are thought to reflect motor preparation. Between 13 individuals of a given species, the acoustic structure of INs and the number of times INs are repeated 14 before song varies considerably. While similar variation in songs between individuals is known to be a 15 result of learning, whether INs are also learned remains poorly understood. Here, using natural and 16 experimental tutoring with male zebra finches, we show that mean IN number and IN acoustic structure 17 are learned from a tutor, independent of song learning. We also reveal biological predispositions in IN 18 production; birds artificially tutored with songs lacking INs still repeated a short-duration syllable, 19 thrice on average, before their songs. Overall, these results show that INs, just like elements in song, 20 are shaped both by learning and biological predispositions and suggest multiple, independent, learning 21 processes underlying the acquisition of complex vocal displays. 22

“…Males were not banded, but if a male was using the same singing perches during subsequent weeks we considered it as the same individual, based on the high improbability that different males would use exactly the same perch week after week in a single territory (Barrantes et al 2008;Fitzsimmons et al 2008). After territory establishment, we searched for a female within each male's territory for 30-40 min each week for up to 4 weeks.…”

In song-learning birds, male song shows a large inter-individual variation that frequently plays an important role in intra-and inter-sexual selection. In other bird groups, such as Galliformes, song learning is absent, and inter-individual song variation is small and expected to play a minor, if any, role in sexual contexts. In the Spot-bellied Bobwhite (Colinus leucopogon) we found that many males have a unique set of song features, and our results suggest that female mate choice in this species is based in part on male song traits. Most paired males in our study had longer songs. In addition, these males established territories in the middle of the breeding season, soon after the onset of the rainy season when increases in herbaceous cover and food resources would likely increase offspring and adult survival.

“…Lekking favours the development of secondary sexual traits, and differences in sexual signals among individuals can be highly important. Although sparsely studied (rare examples include Westcott 1997;Fitzsimmons et al 2008), such systems provide an ideal framework to study individual signature, as learning and recognition of signals can be favoured by the repeated interaction between individuals.…”

Individual Signature in a Lekking Species: Visual and Acoustic Courtship Parameters May Help Discriminating Conspecifics in the Houbara Bustard

Selection pressures acting on both intrasexual competition and intersexual relationships may lead to the emphasis of individual variation and might thus lead to the expression of individual signature. This is particularly true in lek mating systems, where providing information on identity and/or quality to potential mates or congeners of the same sex can be essential for individuals to optimize their reproductive success. Visual and acoustic signals produced during the courtship of the lekking North African Houbara bustard (Chlamydotis undulata undulata), based on field data from wild birds, are investigated here for the first time. Results show that the vocal signals, called booms, are characterized by a very low frequency, a rare phenomenon in birds which should allow booms to propagate over long distances. Results also show that both visual and acoustic signals are individualized and stereotyped between males. Using three methods of analysis, we highlight the acoustic parameters likely to support vocal individual signature and show that such information mainly relies on frequency parameters.
