Abstract

Calls for urgent action to conserve biodiversity under global change are increasing, and conservation of migratory species in this context poses special challenges. In the last two decades the Convention on the Conservation of Migratory Species of Wild Animals (CMS) has provided a framework for several subsidiary instruments including action plans for migratory bird species, but the effectiveness and transferability of these plans remain unclear. Such laws and policies have been credited with positive outcomes for the conservation of migratory species, but the lack of international coordination and on-ground implementation pose major challenges. While research on migratory populations has received growing attention, considerably less emphasis has been given to integrating ecological information throughout the annual cycle for examining strategies to conserve migratory species at multiple scales in the face of global change. We fill this gap through a case study examining the ecological status and conservation of a migratory raptor and facultative scavenger, the red kite (Milvus milvus), whose current breeding range is limited to Europe and is associated with agricultural landscapes and restricted to the temperate zone. Based on our review, conservation actions have been successful at recovering red kite populations within certain regions. Populations however remain depleted along the southern-most edge of the geographic range where many migratory red kites from northern strongholds overwinter. This led us to a forward-looking and integrated strategy that emphasizes international coordination involving researchers and conservation practitioners to enhance the science-policy-action interface. We identify and explore key issues for conserving the red kite under global change, including enhancing conservation actions within and outside protected areas, recovering depleted populations, accounting for climate change, and transboundary coordination in adaptive conservation

18. Extracting reproductive parameters from GPS tracking data for a nesting raptor in Europe.

Abstract

Understanding population dynamics requires estimation of demographic parameters like mortality and productivity. Because obtaining the necessary data for such parameters can be labour‐intensive in the field, alternative approaches that estimate demographic parameters from existing data can be useful. High‐resolution biologging data are frequently available for large‐bodied bird species and can be used to estimate survival and productivity. We extend existing approaches and present a freely available tool (‘NestTool') that uses GPS tracking data at hourly resolution to estimate important productivity parameters such as home range establishment, breeding initiation, and breeding success. NestTool first extracts 42 movement metrics such as time spent within a user‐specified radius, number of revisits, home range size, and distances between most frequently used day and night locations from the raw tracking data for each individual breeding season. These variables are then used in three independent random forest models to predict whether individuals exhibited home range behaviour, initiated a nesting attempt, and successfully raised fledglings. We demonstrate the use of NestTool by training models with data from 258 individual red kites Milvus milvus from Switzerland tracked for up to 7 years, and then applied those models to tracking data from different red kite populations in Germany where detailed observations of nests and their outcomes existed for validation. The models achieved > 90% accurate classification of home range and nesting behaviour in validation data, but slightly lower (80–90%) accuracy in classifying the outcome of nesting attempts, because some individuals frequently returned to nests despite having failed. NestTool provides a graphical user interface that allows users to manually annotate individual seasons for which model predictions exceed a user‐defined threshold of uncertainty. NestTool will facilitate the estimation of demographic parameters from tracking data to inform population assessments, and we encourage ornithologists to test NestTool for different species.

19. Verantwortungsart Rotmilan: Ermittlung von Dichtezentren des Greifvogels in Sachsen-Anhalt.

Abstract

The red kite (Milvus milvus) is the only German breeding bird species of which more than half of its world population lives in Germany. The federal state of Saxony-Anhalt is in turn a main focus of distribution within Germany. To be able to target protective measures on areas of high population densities, the mainpopulation centres of red kite in Saxony-Anhalt should be determined. For density calculation, the method of kernel density estimation (after Silverman 1986) was preferred to a grid fieldbased calculation.A search radius of 10km around each eyrie can be established by telemetry data. In the calculated density map, the density centres are areas with significantly increased settlement density. To delineate the density centres, an absolute threshold was initially tested (four breeding pairs per 34km², as used in Baden-Württemberg), but this was rejected as non-transferable to local conditions. For Saxony-Anhalt, a threshold is proposedthat refers to the average population density of the state and which exceeds this by 50%. The density centres determined with the aid of this relative threshold are mapped and their temporal stability is discussed. [ABSTRACT FROM AUTHOR]
