“…Not only species but also conspecific individuals can differ in how they organize their song elements sequentially, as it has been shown in common nightingales ( Luscinia megarhynchos ) at the song sequence level ( Kipper et al 2004 ) and in Cassin’s vireo ( Vireo cassinii ) at phrase sequence level (where phrases are defined as the smallest repeated discrete units separated by 1–2 s long pauses in this species, Arriaga et al 2016 ). Such among-individual differences can reflect a neutral variation, but also can be linked to individual quality, whereby the sequential organization of song elements can fulfill signaling functions.…”

“…Despite the importance of repeatability calculations from the statistical and the biological perspectives in terms of the accuracy of measurements and the function of traits in the communication, respectively ( Zsebők et al 2017 ), according to our knowledge, previous studies have not provided estimates of repeatability for sequential organization. However, an extreme example for the coding potential of sequential organization was shown in the Cassin’s vireo ( Arriaga et al 2016 ), where individuals had unique sequences implying high repeatability.…”

Sequential organization of birdsong: relationships with individual quality and fitness

Many vocalizing animals produce the discrete elements of their acoustic signals in a specific sequential order, but we know little about the biological relevance of this ordering. For that, we must characterize the degree by which individuals differ in how they organize their signals sequentially and relate these differences to variation in quality and fitness. In this study, we fulfilled these tasks in male collared flycatchers (Ficedula albicollis). We characterized the sequential order of syllables with a network analysis approach and studied the consistency of network variables on distinct time scales (within day, between days, and between years), and assessed their relationship with such quality indicators like age, body condition, arrival date, and fitness related proxies like survival to the next year and pairing success. We found that the syllables were associated nonrandomly with one another and both the frequency differences of consecutive syllables and the number of motif types were higher in the original than in randomized syllable sequences. Average degree and small-worldness showed considerable among-individual differences and decreasing repeatability with increasing time scale. Furthermore, we found relationships between male age and average degree among and within individuals. Accordingly, older males produce syllable sequences by using common syllables less often than younger individuals. However, the network variables showed no relationship with fitness-related variables. In conclusion, the sequential organization of birdsong has the potential to encode individual-specific characteristics, which thus could be used as signal in social interactions and thus potentially could be subject to sexual selection.

“…I recorded birds opportunistically by approaching a known breeding territory and recording the singing male until he either stopped singing or flew too far away to be recorded. In 2013, males were identified based on their association with known breeding territories, and identifications were then confirmed from recordings based on the observation that birds possess individually distinctive repertoires that are organized into diagnostic sequences [ 48 , 49 ]. In May 2014, males were captured and marked with unique colored leg bands, which helped identify the birds during subsequent recordings.…”

Complexity, Predictability and Time Homogeneity of Syntax in the Songs of Cassin’s Vireo (Vireo cassinii)

Many species of animals deliver vocalizations in sequences presumed to be governed by internal rules, though the nature and complexity of these syntactical rules have been investigated in relatively few species. Here I present an investigation into the song syntax of fourteen male Cassin’s Vireos (Vireo cassinii), a species whose song sequences are highly temporally structured. I compare their song sequences to three candidate models of varying levels of complexity–zero-order, first-order and second-order Markov models–and employ novel methods to interpolate between these three models. A variety of analyses, including sequence simulations, Fisher’s exact tests, and model likelihood analyses, showed that the songs of this species are too complex to be described by a zero-order or first-order Markov model. The model that best fit the data was intermediate in complexity between a first- and second-order model, though I also present evidence that some transition probabilities are conditioned on up to three preceding phrases. In addition, sequences were shown to be predictable with more than 54% accuracy overall, and predictability was positively correlated with the rate of song delivery. An assessment of the time homogeneity of syntax showed that transition probabilities between phrase types are largely stable over time, but that there was some evidence for modest changes in syntax within and between breeding seasons, a finding that I interpret to represent changes in breeding stage and social context rather than irreversible, secular shifts in syntax over time. These findings constitute a valuable addition to our understanding of bird song syntax in free-living birds, and will contribute to future attempts to understand the evolutionary importance of bird song syntax in avian communication.

“…Budka et al [8] selected the pulse-to-pulse duration (PPD) of the call as individual-specific feature of the Corncrake(Crex crex), a high percentage of 98 % was achieved when the number of individuals is 122. Arriaga et al [9] used an ensemble of learners to identify individual Cassin's Vireo from the structural properties of their vocalizations. The ensemble achieved 96% accuracy identifying 13 individual birds within the same year and 95% for 8 individual birds across two years.…”

High Accuracy Individual Identification Model of Crested Ibis (Nipponia Nippon) Based on Autoencoder With Self-Attention

As the population and the distribution of Crested Ibis (Nipponia nippon) become larger, it is necessary to propose a highly efficient census method to estimate the population size of the Crested Ibis. Passive acoustic monitoring (PAM) has a very good prospect for the Crested Ibis monitoring. To realize the automatic census of the Crested Ibis with PAM, the automatic individual identification method based on the vocalization is the key technology. A novel individual identification model was proposed in this paper, which built the autoencoder based on LSTM to obtain the meaningful latent representation from the raw recording directly, further, embedded self-attention and putted forward a combined training mode to achieve distinctive latent representation. With this model, nine Crested Ibis individuals were identified accurately, the highest accuracy is 0.971, and the average accuracy reaches 0.958. As for other three species, Little owl (Athene noctua), Chiffchaff (Phylloscopus collybita) and Tree pipit (Anthus trivialis), the better performances were achieved than the existing method, which means the proposed model can provide an alternative method for the individual identification of other bird species.
