Duetting is a collective behavior and might have multiple functions, including joint territory defense mate guarding. An important step toward understanding the adaptive function of bird song to determine if how singing varies seasonally. However, seasonal patterns for duetting species are different from pattern described in which only male sings, because may vary according sex, role (initiator vs responder) level duet organization (individual pair). We investigated whether variation depends...
Abstract Although hissing is a common strategy of defence used by snakes, especially the Phytonidae and Boidae families, few studies have described in detail acoustics components this behaviour. Here we gathered eight recordings from six different boas Brazil extracted acoustic measurements their sounds. We also examined potential our to encode individual identity using discriminant function analyses (DFAs) correlate with body length linear mixed models (LMMs). Boas produce four 12 hisses...
Abstract Vocal individuality is essential for social discrimination but has been poorly studied in animals that produce communal signals (duets or choruses). Song overlapping and temporal coordination make the assessment of more complex. In addition, selection may favor accurate identification pairs over individuals by receivers year-round territorial species with duetting long-term pair bonding. Here, we individual vocal signatures polyphonal duets rufous horneros Furnarius rufus, a...
The weekend effect hypothesis predicts that weekly cycles of human activity impact animal behaviour and physiology. This has been supported in the context recreational natural environments but it is unknown whether also applies to urban animals. We tested this by comparing sentinel (territorial vigilance), foraging vocal behaviours an urban‐dwelling bird, Rufous Hornero Furnarius rufus, between weekdays weekends (and holidays) within a university campus central Brazil. level (noise, traffic...
Abstract Animals can encode information within acoustic signals, particularly, bird songs be remarkably complex and indicate individual identity quality. Two main sets of hypotheses attempt to explain the evolution increased birdsong complexity across large-scale geographic ranges: 1) larger space availability, 2) greater sexual selection intensity, both which would favor more at higher latitudes, seasonal and/or species-poor environments. However, few studies have assessed patterns song for...
Gray-hooded Gull, Chroicocephalus cirrocephalus (Vieillot, 1818), is distributed across South America and considered a resident, with individuals in their non-breeding period able to disperse over long distances. We report the first records of this species from state Espírito Santo, only on Brazilian coast without previous records. suggest that geographical distribution expanding along coast, accordance what has been previously suggested for Gray-hooded Gull.
