The metabolic costs of animal movement have been studied extensively under laboratory conditions, although frequently these are a poor approximation the operating in natural, heterogeneous environment. Construction "energy landscapes," which relate locality to cost transport, can clarify whether, what extent, and how properties attributable environmental heterogeneity. Although behavioral responses aspects energy landscape well documented some fields (notably, selection tailwinds by aerial...
Organic waste can be considered a food subsidy which represents an important source of energy for different species that exploit it. However, it could produce contrasting impacts, both positive and negative. We reviewed terrestrial vertebrates (birds, mammals, reptiles amphibians) rubbish dumps, the impacts produces on them. analysed 159 articles including 98 are present in dumps. Studies come from all over world (including Antarctica), but mainly Europe, North America Africa. Impacts...
Abstract A major barrier to advancing ornithology is the systemic exclusion of professionals from Global South. recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed long-standing pattern highlighting individuals, knowledge, views North, while largely omitting perspectives people based within Neotropics. Here, we review current strengths opportunities practice ornithology. Further, discuss problems with assessing state...
We describe the evolution of outbreak Highly Pathogenic Avian Influenza (HPAI) A(H5N1) in sea lions (Otaria flavescens) South America. At least 24,000 died Peru, Chile, Argentina, Uruguay, and Brazil between January–October 2023. The most plausible route infection is cohabiting with or foraging on infected birds. However, we urge a detailed evaluation actual source given that concomitant massive wild bird mortalities registered Pacific Ocean did not occur Atlantic Ocean.
Abstract The tortuosity of the track taken by an animal searching for food profoundly affects search efficiency, which should be optimised to maximise net energy gain. Models examining this generally describe movement as a series straight steps interspaced turns, and implicitly assume no turn costs. We used both empirical‐ modelling‐based approaches show that energetic costs turns in terrestrial aerial locomotion are substantial, calls into question value conventional models such correlated...
Abstract Understanding the distribution of biodiversity across Earth is one most challenging questions in biology. Much research has been directed at explaining species latitudinal pattern showing that communities are richer tropical areas; however, despite decades research, a general consensus not yet emerged. In addition, global patterns being rapidly altered by human activities. Here, we aim to describe large‐scale richness and diversity terrestrial vertebrate scavenger...
Significance Flapping flight is extremely costly for large birds, yet little known about the conditions that force them to flap. We attached custom-made “flight recorders” Andean condors, world’s heaviest soaring documenting every single wingbeat and when how individuals gained altitude. Remarkably, condors flapped only 1% of their time, specifically during takeoff close ground. This particularly striking as birds were immature. Thus, our results demonstrate even inexperienced can cover vast...
Summary Although drones are becoming very common in the skies, most concerns about their use not focused on possible impact wildlife. We used information available from scientific literature effects of wildlife and complement it with Internet (YouTube) to evaluate whether recreational activities using produce behavioural responses Scientific papers specifically evaluating scarce but increasing. Nonetheless, we found abundant videos which many species different taxonomic groups multiple...
The effects that microorganisms (bacteria, viruses and fungi) have on their hosts remain unexplored for most vulture species. This is especially relevant vultures, as diet consists of carcasses in various stages decomposition, which are breeding grounds potentially pathogenic microorganisms. Here we review current knowledge bacterial, viral mycotic present wild vultures. We consider potential to cause disease vultures whether this poses any population‐level threats. Furthermore, address the...
We report a massive mortality of 5,224 sea lions (Otaria flavescens) in Peru that seemed to be associated with highly pathogenic avian influenza A(H5N1) virus infection. The transmission pathway may have been through the close contact infected wild birds. recommend evaluating potential among lions.
ABSTRACT We report a massive mortality of more than 3,000 sea lions ( Otaria flavescens ) Peru associated with Highly Pathogenic Influenza Virus (H5N1). The transmission pathway H5N1 may have been through the close contact infected wild birds. cannot rule out direct among lions.
The highly pathogenic avian influenza H5N1 is an emerging and unexpected threat to many wild animal species, which has implications for ecological processes, ecosystem services conservation of threatened species. International collaboration information-sharing essential surveillance, early diagnosis the provision financial technical instruments enable worldwide actions.
Abstract The development of conservation strategies to protect viable populations scavenging birds requires the existence adequate and safe food supplies in wild. Early reports on Andean condors Vultur gryphus diet recorded guanacos rheas, dominant herbivores since Pleistocene, as their main Patagonia. However, past century, guanaco rhea have notably decreased a consequence introduced livestock, other exotic mammals colonized region. We study spatial temporal variation condors' determine...
Abstract Understanding the factors underlying species coexistence is a major focus in community ecology. When dealing with competition between native and exotic species, competitive exclusion of ‘weaker’ can have consequences for biodiversity conservation. We examined interspecific interactions during foraging black vultures Coragyps atratus Andean condors Vultur gryphus Southern Argentina. Previous studies suggest facilitatory them. However, most parts their distribution ranges, these did...
Despite the fact that parrots (Psitacifformes) are generalist apex frugivores, they have largely been considered plant antagonists and thus neglected as seed dispersers of their food plants. Internal dispersal was investigated by searching for seeds in faeces opportunistically collected at communal roosts, foraging sites nests eleven parrot species different habitats biomes Neotropics. Multiple intact seven five families were found a variable proportion from four species. The mean number...
Accelerometry has been used to identify behaviours through the quantification of body posture and motion for a range species moving in different media. This technique not applied flight same degree, having only distinguish flapping from soaring flight, even though identifying type could provide important insights into factors underlying movement paths birds. may be due complexities interpreting acceleration data, as aerial environment influenced by phenomena such centripetal (pulling-g)....
