Abstract Passive acoustic monitoring (PAM) is increasingly popular in ecological research, but recording and analyzing large amounts of data still a critical bottleneck for the long‐term multiple species. We evaluated how temporal spatial sampling effort affects species diversity estimates using set 14,045 1‐min recordings from various neotropical birds anuran communities. Our goals were to evaluate (i) daily vocal activity cycle anurans, (ii) effect structure (e.g., number minutes listened...
The sensory basis of the navigational map remains one most important and intriguing questions in animal behaviour. In birds, odours have been hypothesized to provide primary source information. Convincing tests shown that experienced homing pigeons rely on information obtained at sites where they are exposed natural odours, even if subsequently released (without additional olfactory information) a different site. These findings interpreted as support for hypothesis. Using this...
Migration is a widespread phenomenon among birds and likely to be subject strong selective pressures. Birds' annual routines behaviors might expected change during their different life history stages, resulting in different, age-related migration patterns. However, although has been the of many publications, differences have received little attention. The present study examined changes individual habits lesser black-backed gulls, Larus fuscus. We analyzed data from 10-year (1998–2007)...
Young animals in a broad range of taxa solicit care from their parents with begging displays, which are used at least partly for competition among brood or litter mates. The effect other offspring on an individual's own display varies across studies, however, increasing its intensity some, but not changing, even decreasing it, others. One possible reason this discrepancy is that the potential pay-off more intense depends only how intensely littermates begging, also long individual has been...
Some animals migrate long distances to exploit important seasonal food resources in the northern regions of hemisphere, whilst avoiding winter starvation. Changes individual's age and navigational skills are likely affect migration, which turn influences geographic distribution individuals. Processes such as sexual maturation abilities affected by age, is thus a key factor understanding migration patterns differences ranges. In present study, we investigated effects on population Lesser...
The dorsolateral area of the hippocampal formation birds is commonly assumed to play a central role in processing information needed for geographical positioning and homing. Previous work has interpreted odour-induced activity this region as evidence an 'olfactory map'. Here, we show, using c-Fos expression marker, that neuronal activation pigeons primarily response odour novelty, not spatial distribution sources would be necessary olfactory map. Pigeons exposed odours had significantly more...
ABSTRACT Nestling calls play a major role in parent-offspring interactions, especially as recognition signals or of need. However, nestling birds undergo developmental changes that are likely to influence their vocalizations. In this study, we investigated Spanish sparrows Passer hispaniolensis during the period between hatching and fledgling, attempted identify specific call features associated with changes. We recorded nine individual nestlings at 2 (n = 8), 4 9), 6 8 8) 10 5) days old....
SUMMARY When travelling in groups, animals frequently have to make decisions on the direction of travel. These can be based consensus, when all individuals take part decision (i.e. democratic decision; social information), or leadership, one member a minority members despotic personal information). Here we investigated whether decision-making navigation small flocks is decisions. Using individual and flock releases as experimental approach, compared homing performances pigeons that fly...
ABSTRACT Nestling begging behaviour has long been seen as a signal by which nestlings solicit care from parents and most of the existing evidence provides some support for it being an honest signal. Begging is multicomponent in both sound vision components are usually important. Although known that encodes information about nestling hunger present knowledge specific behavioural features convey still scarce. The aim this study was to describe calls Iberian Azure-winged Magpie Cyanopica...
The preservation of historical and contemporary data safeguards our scientific legacy. Bioacoustic recordings can have as well value should be assessed for their conservation requirements. Unpreserved bioacoustics are generally not referenced frequently at high risk loss by material degradation and/or misplacement. In this study we investigated the status sets natural sound made in Portugal from 1983 until 2010 inclusive. We evaluated on basis rate loss, degree to which unpreserved could...
The role of odors in the long-distance navigation birds has elicited intense debate for more than half a century. Failure to resolve many issues fueling this is due at least part absence controls variety non-specific effects that have on navigational process. present experiments were carried out investigate whether olfactory inputs are involved only "activation" neuronal circuitry or also playing providing directional information. Experienced adult pigeons exposed controlled stimuli during...
Vocal communication is fundamental to regulate the social interactions in most gregarious species especially after dispersal movements for foraging or predator escape. A common acoustic signal may be beneficial group members and critical that disperse large distances like parrots. In this study, we investigated whether parrots flight-calls carry species-specific characteristics tested its variability within across species. We also assessed hypothesis of relationship between similarity...
The migration is energy-demanding and expected to greatly affect the distribution of individuals over species range condition choice migratory routes. We investigated wintering distributions flyways use geographically contiguous populations Lesser Black-backed Gulls ( Larus fuscus ) difference in population winter age structure between flyways. Recoveries metal ringed pulli from Denmark, Sweden, Finland were used. results showed that can have distinct patterns More importantly, we found...
Capsule Single-female nests had lower parental expenditure but higher effort than those of paired-females.
Temperature plays a central role in the life of birds, especially during egg incubation and nestling thermal brooding.I investigated nest temperature variation relative to ambient an enclosed nest-builder species (Spanish sparrow Passer hispaniolensis) open-cup (Iberian azurewinged magpie Cyanopica cooki).The data for empty nests showed that structure acted as buffer which reduced impact night-time within nest.The effect was increased at dawn.The presence adult difference between...
No médio-baixo curso do rio Piracicaba (MG), afluente Doce, na região Sudeste país, está instalada a Usina Hidrelétrica Guilman Amorim (140MW). Entre as atividades da gestão ambiental usina, tem sido realizado o monitoramento qualidade água desde 1995, antes de se iniciar obras sua construção. Neste estudo, foram selecionados dados sete parâmetros monitorados ao longo um período 20 anos (1995-2015). Os avaliados por meio estatísticas descritivas e testes não paramétricos para detecção...
