Abstract

Biodiversity knowledge gaps, which limit scientific research and conservation planning, are especially acute for the most poorly known organisms. Citizen science offers a powerful and effective means to fill these gaps. The recent growth of citizen‐science platforms has resulted in near‐complete coverage of global avian diversity (~11,849 species). Because shrinking knowledge gaps increasingly reveal meaningful absences, we evaluated the potential of citizen‐science data to establish "lost" bird taxa: those without documentation for more than 10 years. Collating more than 42 million photographic, audio, and video records returned 144 bird species (1.2%) as lost, the majority of which (62%) are in danger of extinction. The higher the coverage by citizen scientists and the longer the interval since their last documented record, the more likely that lost birds are to be imperiled. Our approach provides a data‐driven and reproducible method to identify lost species and elucidates high‐priority knowledge gaps to inform future conservation action. [ABSTRACT FROM AUTHOR]

Abstract

The Kangean islands are a biologically poorly known archipelago situated in the Java Sea, Indonesia, 120 km directly north of Bali and 124 km off East Java. These islands host an avifauna comprising at least 13 endemic subspecies, two of which have by some sources recently been considered species. We combine historical published literature with our own surveys of the archipelago in 2007-2008, 2010 and 2023 to produce an updated list of the islands' birds (n=140 species) and their distribution across the islands. We evaluate in more detail the conservation status of all endemic taxa, as well as several others we consider to be of concern. Despite its current listing as Vulnerable on the IUCN Red List, the endemic Kangean Tit-babbler Mixornis prillwitzi is common in highly degraded habitats, including scrub, and is probably one of the islands' least threatened birds. However, because of trapping, the archipelago's endemic taxon of Red-breasted Parakeet Psittacula alexandri kangeanensis, and its populations of Green Junglefowl Gallus varius and Common Hill Myna Gracula religiosa are likely at risk of extirpation. The endemic taxon of White-rumped Shama Copsychus malabaricus nigricauda, sometimes afforded species rank as 'Kangean Shama', may already be (at least functionally) extinct in the main archipelago, with no record since 2007-2008. We recommend longer and more detailed surveys of the islands' birds, and that an effective protected area is established on the main Kangean island, which hosts the largest area of remaining forest in the archipelago and most of its endemic taxa.

7. Equivocal support for the climate variability hypothesis within a Neotropical bird assemblage.

Author

Abstract

The climate variability hypothesis posits that an organism's exposure to temperature variability determines the breadth of its thermal tolerance and has become an important framework for understanding variation in species' susceptibilities to climate change. For example, ectotherms from more thermally stable environments tend to have narrower thermal tolerances and greater sensitivity to projected climate warming. Among endotherms, however, the relationship between climate variability and thermal physiology is less clear, particularly with regard to microclimate variation—small‐scale differences within or between habitats. To address this gap, we explored associations between two sources of temperature variation (habitat type and vertical forest stratum) and (1) thermal physiological traits and (2) temperature sensitivity metrics within a diverse assemblage of Neotropical birds (n = 89 species). We used long‐term temperature data to establish that daily temperature regimes in open habitats and forest canopy were both hotter and more variable than those in the forest interior and forest understory, respectively. Despite these differences in temperature regime, however, we found little evidence that species' thermal physiological traits or temperature sensitivity varied in association with either habitat type or vertical stratum. Our findings provide two novel and important insights. First, and in contrast to the supporting empirical evidence from ectotherms, the thermal physiology of birds at our study site appears to be largely decoupled from local temperature variation, providing equivocal support for the climate variability hypothesis in endotherms. Second, we found no evidence that the thermal physiology of understory forest birds differed from that of canopy or open‐habitat species—an oft‐invoked, yet previously untested, mechanism for why these species are so vulnerable to environmental change.

Subjects
multispecies groups, mixed flocks of birds
Abstract

The literature on mixed-species flocks references a wide variety of bird associations. These studies, however, have used an array of unstructured characteristics to describe flocks, ranging from the temporal occurrence of flocking to the identity and behavioural features of constituent members, with little consensus on which key traits define and characterize a mixedspecies flock. Moreover, although most studies report species-specific roles, there is no clear consensus about what these roles signify nor how to define them. This lack of consistency limits our ability to compare flocks from different habitats, regions, and species pools. To unify this sizable body of literature, we reviewed and synthesized 538studies on mixed-species flocks.We propose 13 categories to classify mixed-species flocks using behavioural and physical traits at the flock and participant level, as well as the habitat where the flock occurs. Lastly, we discuss the historical terminology for different species roles and propose definitions to clarify and distinguish among nuclear, leader, sentinel, and flock-following species.We envision that these guidelines will provide a universal language for mixed-species flock research, paving the way for future comparisons and new insight between different regions and systems.

17. Supplementary tables and figures to support the main text from Long-term changes in avian biomass and functional diversity within disturbed and undisturbed Amazonian rainforest

Abstract

Recent long-term studies in protected areas have revealed the loss of biodiversity, yet the ramifications for ecosystem health and resilience remain unknown. Here, we investigate how the loss of understory birds, in the lowest stratum of the forest, affects avian biomass and functional diversity in the Amazon rainforest. Across approximately 30 years in the Biological Dynamics of Forest Fragments Project, we used a historical baseline of avian communities to contrast the avian communities in today's primary forest with those in modern disturbed habitat. We found that in primary rainforest, the reduced abundance of insectivorous species led to reduced functional diversity, but no reduction of biomass, indicating that species with similar functional traits are less likely to coexist in modern primary forests. Because today's forests contain fewer functionally redundant species—those with similar traits—we argue that avian communities in modern primary Amazonian rainforests are less resilient, which may ultimately disrupt the ecosystem in dynamic and unforeseen ways.

Abstract

How are rainforest birds faring in the Anthropocene? We use bird captures spanning > 35 years from 55 sites within a vast area of intact Amazonian rainforest to reveal reduced abundance of terrestrial and near‐ground insectivores in the absence of deforestation, edge effects or other direct anthropogenic landscape change. Because undisturbed forest includes far fewer terrestrial and near‐ground insectivores than it did historically, today's fragments and second growth are more impoverished than shown by comparisons with modern 'control' sites. Any goals for bird community recovery in Amazonian second growth should recognise that a modern bird community will inevitably differ from a baseline from > 35 years ago. Abundance patterns driven by landscape change may be the most conspicuous manifestation of human activity, but biodiversity declines in undisturbed forest represent hidden losses, possibly driven by climate change, that may be pervasive in intact Amazonian forests and other systems considered to be undisturbed.

Abstract

The article focuses on the first records of European-banded Lesser Black-backed Gull Larus fuscus in America on November 16 and 20, 2002 in Rio Grande de Arecibo, Puerto Rico and on October 7, 1997 at Cold Spring Harbor in Long Island, New York. The sighted gulls were banded in Iceland and the Netherlands. Data from the Christmas Bird Counts (CBC) show that the number of sightings of Lesser Black-backed Gulls in North America has increased rapidly from 1990 to 2005. The contribution of British birds to the American wintering population is explained. It recommends color-banding of wintering birds in America and of birds breeding in Iceland and Greenland.

Across approximately 30 years in the Biological Dynamics of Forest Fragments Project, we used a historical baseline of avian communities to contrast the avian communities in today's primary forest with those in modern disturbed habitat. We found that in primary rainforest, the reduced abundance of insectivorous species led to reduced functional diversity, but no reduction of biomass, indicating that species with similar functional traits are less likely to coexist in modern primary forests. Because today's forests contain fewer functionally redundant species-those with similar traits-we argue that avian communities in modern primary Amazonian rainforests are less resilient, which may ultimately disrupt the ecosystem in dynamic and unforeseen ways.
