Previous research, predominantly employing human surrogates, has consistently shown that urban-dwelling prey exhibit greater tolerance for the approach of human beings compared to their counterparts in rural or suburban habitats. However, it is essential for urban animals to retain sensitivity to genuine predators despite their habituation to non-lethal human presence. In this study, we investigated the escape behavior of three bird species (<i>Pica pica</i>, <i>Streptopelia orientalis</i>, and <i>Spilopelia chinensis</i>) in response to both human and genuine cat predators. We compared the flight initiation distance (FID) and distance fled (DF) when approached by one person, one person with a cat, and two persons in urban and suburban environments. Our findings reveal that urban birds exhibit heightened tolerance (habituation) to approaching predators in urban environments. However, contrary to our expectations, urban birds showed similar FID and DF when approached by one person with a caged cat compared to one or two persons, suggesting a lack of distinction between human and cat predators or reluctance to make different escape decisions. In addition, DF was significantly influenced by the distance to refuge but did not differ between urban and suburban habitats. Our study supports the general risk-taking hypothesis, indicating similar reactions to different predators, and underscores the appropriateness of using human surrogates to study escape behaviors, even in habituated urban environments.</p>","PeriodicalId":54895,"journal":{"name":"Journal of Ornithology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present results regarding long-term (eleven breeding seasons) impact of nest parameters on breeding characteristics in Great Tits (<i>Parus major</i>) and Eurasian Blue Tits (<i>Cyanistes caeruleus</i>) in a deciduous forest and an urban parkland study area. Our findings indicate that in Great Tits and Eurasian Blue Tits the number of fledglings (and in Eurasian Blue Tits also clutch size tended to be) was positively associated with lining mass and was influenced by the study area, with higher values observed in the forest. Additionally, there was a relationship between lining mass and higher hatching success in both tit species. We also demonstrated that both clutch size and number of fledglings were higher in Great Tits in the forest and in Eurasian Blue Tits the number of fledglings was higher in the forest. The study site also impacted hatching success, with Great Tits showing higher rates in the forest, and fledging success for Eurasian Blue Tits being higher in the forest. The number of fledglings differed between years in Great Tits and hatching success and fledging success differed between years in both Great and Eurasian Blue Tit species.

However, there is no consensus on how life-history traits associate with migration, and on migrant’s position at the slow–fast continuum of life history. Birds subject to different selective pressures are likely to show distinct patterns from each other. We used data from egg collections to investigate the relationship between reproduction and migration by assessing clutch size and egg size of 58 migratory and non-migratory tyrant flycatchers breeding in South America. We first compared clutch size and egg size of migrants and non-migrants, and then we assessed how migrants balance these reproductive traits with migration distance. Despite energy expenditure faced by migrants during their journey, migratory behavior was not a factor influencing clutch size and egg size of migrants and non-migrants. On the other hand, migration distance positively correlated with clutch size in migrants. Our study provides evidence that migration distance may constrain migrants in terms of costs and pressure reproduction in the direction of a faster life-history strategy, while migratory behavior per se may not be a determinant to place migrants in the slow–fast continuum of life history. Thus, among tyrant flycatchers breeding in South America variation in migratory strategies might be more important than migratory behavior in interacting with life-history traits.

There have been many investigations of vocal behaviour and its important role in territory defense and mate attraction in birds; however, the effect of the density of conspecific neighbours on avian communication has received little attention. In this study, we reviewed the literature on the influence of local density on vocal communication in birds, exploring how the number of conspecific neighbours influences avian vocal behaviour, by conducting a literature review following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in two databases: Web of Science and Scopus. We also included additional articles from a more flexible search in Google Scholar. We found 19 studies of birds that included data on vocal behaviour in relation to the number of conspecific neighbours. The majority of these studies (14 of 19) showed that local density influences avian vocal behaviour. Overall, these studies revealed an effect of local density of conspecifics on song rate (expressed as song rate, syllable rate, solo song rate, or singing rate). Other vocal behaviours that were shown to vary with local density included song-type switching, song duration, peak frequency, and song variation. Most studies focused on temperate-zone species where males are the predominant singers. Our results reveal a bias towards the study of male songs in the context of local density, with very few studies on female song; this corresponds with a historical geographical focus on temperate birds. We present experimental design suggestions for future investigations, including predictions for males and females of tropical and temperate species. Finally, we argue that more research on this topic is needed, and that investigations of vocal communication will benefit from further study of the influence of density on avian vocal behaviour.</p>","PeriodicalId":54895,"journal":{"name":"Journal of Ornithology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying where, when, and how these impacts may happen is key to understanding, and planning for, the population-level effects of climate change. This study assesses how climate change will impact the breeding and non-breeding areas of the European Bee-eater <i>Merops apiaster,</i> a long-distance migratory bird, by combining correlative species distribution models with recent tracking data to account for population connectivity between breeding and non-breeding sites. The three populations studied (Iberian, German, and Bulgarian) demonstrated different levels of exposure to climate change, as well as different patterns of connectivity. The Iberian breeding population showed high exposure to climate change in both its breeding and non-breeding sites, which may result in significant, interacting impacts on this population. In contrast, breeding populations in Germany are likely to benefit from climate change, both in their breeding and non-breeding range. Connectivity also varied; while most populations demonstrated extremely high connectivity between breeding and non-breeding sites, the Iberian population was substantially more behaviourally flexible, indicating there may be some adaptive capacity of this population to change non-breeding sites if some become less suitable due to climate change. Incorporating breeding and non-breeding areas into species distribution modelling highlights how the impacts of climate change may combine into multiplicative impacts across a species’ annual cycle, and how combining methodologies and data sources can provide greater insight into the impact of climate change on migratory species and, in turn, inform conservation action.</p>","PeriodicalId":54895,"journal":{"name":"Journal of Ornithology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can be particularly relevant during the breeding season when disturbance by researchers can affect birds on various aspects, including nest and chick survival, physiology, and chick body condition. Researcher effects on the chicks’ body condition have been shown in some species, but were apparently absent in others. Here, we investigate whether varying levels of handling influences the body condition of Eurasian whimbrel (<i>Numenius phaeopus</i>) chicks, using data collected on 88 individuals handled up to 11 times, during two breeding seasons. We found that neither the handling event (ordinal occasion when a chick was handled) nor the handling interval (period between two consecutive handling events) affected the chick’s body condition, but we found evidence that body condition is individually consistent during development. Hence, the levels of handling in our study did not have an apparent effect on Eurasian whimbrel chicks’ body condition.
