Article
Full-text available
Understanding species-environment relationships is key to defining the spatial structure of species distributions and develop effective conservation plans. However, for many species, this baseline information does not exist. With reliable presence data, spatial models that predict geographic ranges and identify environmental processes regulating di...
Article
Climate change is expected to have a profound impact on species distributions, contracting suitable climate space. Biodiversity areas are important to mitigate these negative effects but are static by design and thus do not account for future projections of species distributions. The Harpy Eagle Harpia harpyja has a broad range across lowland Neotr...
Article
Accurately demarcating distributions of biological taxa has long been at the core of ecology. Yet our understanding of the factors defining species range limits is incomplete, especially for tropical species in the Global South. Human-driven threats to the survival of many taxa are increasing, particularly habitat loss and climate change. Identifyi...
Article
Individual diet specialization is known to occur in populations of generalist predators, where specific individuals develop specialist feeding strategies. Diet specialization has been reported in many raptor species and it may be an important driver of intraspecific population structure. Here, we quantify the diet of Peregrine Falcons Falco peregri...

Full-text available
Quantifying home range size and habitat resource selection are important elements in wildlife ecology and are useful for informing conservation action. Many home range estimators and resource selection functions are currently in use. However, both methods are fraught with analytical issues inherent within autocorrelated movement data from irregular...
Article
Quantifying habitat use is important for understanding how animals meet their requirements for survival and provides information for conservation planning. Currently, assessments of range-wide habitat use that delimit species distributions are incomplete for many taxa. The Harpy Eagle (Harpia harpyja) is a raptor of conservation concern, widely dis...
Preprint
Full-text available
Knowledge gaps regarding distribution, habitat associations, and population size for rare and threatened range-restricted taxa leads to uncertainty in directing conservation action. Quantifying range metrics and species-habitat associations using Species Distribution Models (SDMs) with remote sensing habitat data can overcome these setbacks by esta...
Preprint
Full-text available
A current biogeographic paradigm states that climate regulates species distributions at continental scales and that biotic interactions are undetectable at coarse-grain extents. However, recent advances in spatial modelling show that incorporating food resource distributions are important for improving model predictions at large distribution scales...
Preprint
Full-text available
Quantifying resource partitioning between co-occurring species has important ecological and evolutionary implications. Yet, few studies compare resource overlap in both geographic and environmental space. We test whether the habitat requirements of two closely related Neotropical forest eagles, the crested eagle (Morphnus guianensis) and harpy eagl...
Preprint
Full-text available
Many range-restricted taxa are currently experiencing population declines yet lack fundamental information regarding distribution and population size. Establishing baseline estimates for both these key biological parameters is however critical for directing conservation planning for at-risk range-restricted species. The International Union for the...
Article
Full-text available
Most raptor populations are declining and nearly a fifth are threatened with extinction; thus there is a need to increase collaboration to ensure efficient and effective research, management, and conservation. Here, we introduce the Global Raptor Impact Network (GRIN; www.globalraptors.org), a tool to enhance collaboration and conservation impact o...

Individual diet specialization is known to occur in populations of generalist predators, where specific individuals develop specialist feeding strategies. Diet specialization has been reported in many raptor species, and it may be an important driver of intraspecific population structure. Here, we quantify the diet of five breeding pairs of Peregri...

Article
Full-text available
Determining a species’ geographic range is important for conservation planning, yet this information is lacking for many raptors. In rapidly changing environments, defining current and predicting future distributions can help define priority areas for monitoring and research. The Laggar Falcon (Falco jugger) is a rare and understudied raptor reside...
Article
Accurate species distribution data across remote and extensive geographic areas are difficult to obtain. Here, we use bioclimatic envelope models to determine climatic constraints on the distribution of the migratory Saker Falcon Falco cherrug to identify areas in data‐deficient regions that may contain unidentified populations. Sakers live at low...
Article
Full-text available
Among true falcons (Falco sp.), the lanner falcon (F. biarmicus), due to its rarity, has always been viewed as an ‘oddity’, even the name has a contorted history, with both common and scientific names being subject to debate. Unfortunately, the Latinisation of the common name for taxonomic purposes (F. lanarius) produced further confusion. Indeed,...

Full-text available
Explaining species distributions and identifying environmental constraints on species’ ecological niches is a central goal in conservation biogeography. A current paradigm in biogeography states that climate regulates species distribution at macro-scales and that biotic interactions are unimportant due to the large extent and the inherent noise in...

Defining bird distributions across remote and extensive geographic areas is a difficult and challenging task. The migratory Saker Falcon (Falco cherrug) is an endangered raptor with a broad Palearctic range, but with poorly-known distribution across core range states in Asia. Sakers live at low densities, across large ranges in remote regions, maki...

Accurate species distribution data across remote and extensive geographic areas are difficult to obtain. Species Distribution Models (SDMs) address distribution knowledge gaps by correlating environmental conditions from known occurrences, and predicting new areas of habitat suitability. SDMs can direct population surveys, and are an effective tool...
Article
Full-text available
Individual diet specialization occurs in many populations of generalist predators, with specific individuals developing specialist strategies in their feeding behaviour. Intraspecific resource partitioning is hypothesised to be common amongst species in higher trophic levels where competition for resources is intense, and a key driver in breeding s...
Article
Full-text available
Dense island sub-populations of Peregrine Falcons Falco peregrinus are common around the British Isles. Lundy offers a unique opportunity to study this specific area of Peregrine ecology. Manx Shearwaters Puffinus puffinus comprised a significant proportion of the prey spectrum; other important prey included: Herring Gulls Larus argentatus, Domesti...
Article
Full-text available
Previous research into the diet of Peregrine Falcons Falco peregrinus in the British Isles has focused on the north of the country and urban areas. Little is known of prey of pairs breeding on the coasts of South West England, despite an increase in the population. We need to know what these birds are eating, as their diet may affect their breeding...

Eurasian Kestrels (Falco tinnunuclus) are experiencing population declines throughout their range in the UK. In response, we aim to explore the spatial ecology and diet of the kestrel population across southern England with recommendations for raptor conservation.
Project
Determine the global distribution for the Critically Endangered Philippine Eagle and estimate breeding pair population density throughout their known range. Our overall goals are to map potential habitat throughout the Philippine Eagle range, and estimate breeding pair density within predicted habitat. Further, we will conduct an assessment of the proportion of predicted habitat within protected area networks, and perform a gap analysis for new protected area designations.

The Global Raptor Impact Network (GRIN) is a collaborative platform to support the global science of raptor ecology and conservation by collecting, storing, analyzing, and distributing information about nocturnal and diurnal raptors.
