This range expansion is not aligned with changes in climatic conditions or the distribution of their historic prey (P. paludosa). The Eltonian Noise Hypothesis (ENH), which posits that interactive (biotic) factors have stronger effects on species’ distributions at local scales, predicts that non-interactive (abiotic) factors are generally more relevant at geographic extents. However, in this study, we explore the R. sociabilis range shift as a potential counterexample of the ENH. Under the biotic-abiotic-mobility (BAM) framework, we explore the role of biotic and abiotic factors in the northward range expansion of this endangered species. Over the past 15 years, R. sociabilis have begun consuming the more-abundant invasive snails more often, while increasing in bill size, expanding ~175 km northward from previous range limits in the Kissimmee River Valley. We developed ecological niche models using 3 algorithms (Maxent, GLM, ellipsoids) and found stability in climatic suitability between past and present models. Moreover, although native snails occur in northern Florida, R. sociabilis have had a historically patchy northern distribution due in part to the availability of appropriate wetland conditions. We found a strong latitudinal cline, with bill length increasing with latitude at least through 2020, suggesting that this morphological change broadened the species’ biotic suitable area and distributional potential. The interplay between changes in phenotype and biotic interactions has been poorly documented in distributional ecology, given a lack of rich occurrence datasets. Here, we highlight a case in which a biological invasion and subsequent changes in morphology and diet have facilitated expansion of a specialized predator into areas that were unsuitable until recently.","PeriodicalId":19617,"journal":{"name":"Ornithology","volume":"54 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141110761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over 4 billion dollars are spent by hobby bird feeders in the United States each year alone. However, there is mixed evidence whether wildlife feeding is beneficial, including when it is implemented as a conservation management tool, a targeted experimental design, or an avocation. Much of the current evidence suggests that providing supplemental food is advantageous to the reproductive output and general survival of focal taxa. However, many of these studies are limited in scope and duration, leaving possible negative impacts unaddressed. This is particularly true regarding passive backyard feeding, which describes the majority of supplemental feeding, including the immense effort of millions of public enthusiasts. Here we show that winter supplemental feeding prior to reproduction had no significant impact on a range of reproductive parameters in a resident, montane passerine species, the Mountain Chickadee ( Poecile gambeli ). This population resides in an intact natural environment with no exposure to supplemental food beyond our experimental treatments, and individual birds were tracked across six years using radio frequency identification technology. Our results add to the growing evidence that supplemental feeding alone, isolated from the effects of urban environments, may have little to no impact on the population dynamics of some avian taxa.","PeriodicalId":19617,"journal":{"name":"Ornithology","volume":"11 1","pages":"1 - 1"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73971081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The biotic and abiotic drivers of timing of breeding and the consequences of breeding early in changing world","authors":"A. Sutton, Nikole E. Freeman","doi":"10.1093/ornithology/ukad017","DOIUrl":"https://doi.org/10.1093/ornithology/ukad017","url":null,"abstract":"Abstract The decision of when to breed is an important determinant of individual fitness. However, despite a multitude of studies investigating the intraspecific relationship between timing of breeding and reproductive performance, less is known about why the strength of this relationship varies between species. Furthermore, environmental change has the potential to alter the relationship between lay date and fitness, but there is still a limited understanding of what mechanisms drive these differential responses to change environmental conditions. We propose that the potential effects of environmental change on the relationship between timing of breeding and fitness are dependent on 2 primary factors: (1) the potential constraints imposed by breeding early and (2) the drivers of higher fitness of early breeders. We first summarize multiple hypotheses proposed to explain why breeding early, either based on absolute date or relative to conspecifics, increases fitness. We then summarize the factors that may constrain when individuals initiate breeding, including limits on the ability to advance their lay date or extend the length of their breeding season under favorable conditions. Understanding constraints on the timing of breeding allows for the identification of obligate (single-brooded species that do not attempt to breed after a specific date) and facultative (predominantly multi-brooding species that have long breeding seasons) early breeding species that are likely differently affected by climate change. Finally, we propose a simple mathematical formula that incorporates the costs and benefits associated with early breeding to quantify how climate change could influence the benefits of early breeding and either mitigate or exacerbate the costs. Our cost-benefit approach provides a clear framework to predict how species may shift the timing of their breeding to maximize fitness in a changing world. LAY SUMMARY When individuals breed has important impact on reproductive performance and individual fitness. We synthesize the literature on why breeding early is beneficial and why not all individuals can breed early. Environmental change will alter the benefits of breeding early and may impact some species more than others. We propose a cost-benefit framework to determine how environmental change influences fitness and to predict future responses to a changing world. We also provide guidance on how data could be extracted from existing datasets to apply our cost-benefit framework to bird species in the wild.

{"title":"The adaptive significance of off-lek sociality in birds: A synthetic review, with evidence for the reproductive benefits hypothesis in Long-wattled Umbrellabirds","authors":"H. L. Anderson, Jorge Olivo, J. Karubian","doi":"10.1093/ornithology/ukad021","DOIUrl":"https://doi.org/10.1093/ornithology/ukad021","url":null,"abstract":"ABSTRACT Anecdotal evidence suggests that lekking birds exhibit considerable variation in form and degree of sociality away from the lek, yet this phenomenon has received very little theoretical or empirical research attention. Here, we provide the first synthetic literature review of off-lek sociality in birds and develop a conceptual framework for the potential adaptive function of off-lek sociality across lekking taxa. We then present a case study of the Long-wattled Umbrellabird (Cephalopterus penduliger), where we find support for the hypothesis that off-lek sociality is primarily driven by male reproductive incentives for coordinating lek attendance during the breeding season. During periods of high lekking activity, male umbrellabirds depart the lek in highly coordinated groups and maintain larger off-lek social groups relative to periods of low lekking activity. These seasonal differences in off-lek sociality do not occur in females, are not explained by patterns of foraging behavior, and are expected to confer individual-level benefits for participating males. Both the literature review and empirical study of umbrellabirds suggest that off-lek interactions and behavioral strategies may shape sexual selection processes at leks in important ways. Further research into this historically understudied area of lekking species' behavioral ecology will likely deepen our understanding of the evolutionary dynamics of lek mating. LAY SUMMARY Social behavior away from the lek may influence and interact with sexual selection processes in important ways, yet this component of lekking species' behavioral ecology remains very poorly known. A synthetic literature review suggests considerable diversity in the form and degree of off-lek sociality among lekking birds, both within and between species. Potential adaptive explanations for the function of off-lek sociality in a given species include foraging enhancement, predation avoidance, and mating benefits. In Long-wattled Umbrellabirds, we find that the size and coordination of male off-lek groups increases during the mating season. This pattern is not observed in females and is not related to the proportion of fruit in the diet. We suggest that off-lek sociality in umbrellabirds enables males to synchronize foraging and display periods, which is expected to confer individual-level reproductive benefits.

We confirm previous results of the Crested Shrikejay (Platylophus galericulatus) as comprising its own taxonomic family and find strong support for its sister relationship to laniid shrikes. We also find strong support that the African-endemic genus Eurocephalus, which comprises two allopatric species (E. ruppelli and E. anguitimens), are not “true-shrikes.” We propose elevating the white-crowned shrikes to their own family, Eurocephalidae. LAY SUMMARY Understanding how species are related (systematics) and classified (taxonomy) is important to the study of the world's biodiversity. Recent work has raised doubt about the phylogenetic placement of the Crested Shrikejay (Platylophus galericulatus) and Eurocephalus, the white-crowned shrike genus, traditionally considered within the crow and jay family, Corvidae, and the shrike family, Laniidae, respectively. We collected a genome-wide dataset for all genera of shrikes, crows, and jays to determine their evolutionary histories with phylogenetic methods. We confirm that the Crested Shrikejay constitutes a family-level lineage most closely related to Laniidae, not Corvidae. We show for the first time that Eurocephalus also represents a family-level lineage separate from shrikes and more closely related to crows and jays. We propose a new avian family, Eurocephalidae, the white-crowned shrikes, for these two African-endemic birds.
