“…It is possible that a larger number of raptor species have temporarily visited areas they were not (routinely) using before the pandemic, in response to changing levels of human activity, such as urban parks, beaches, or waste management centers during operating hours. A recent example from a seabird colony in the Baltic Sea revealed a previously unknown human ‘shielding effect’: the absence of tourists in 2020 from the island was associated with a sevenfold increase in the presence of white-tailed eagles ( Haliaeetus albicilla ), which in turn appeared to cause a 26% reduction in common murre ( Uria aalge ) productivity compared to the long-term average ( Hentati-Sundberg et al, 2021 ). This provides a striking example of how seemingly benign tourist activity can render a potentially attractive foraging area unsuitable for a raptor.…”

“…populations (Hipfner et al, 2012 ). In a natural experiment, Hentati‐Sundberg et al ( 2021 ) confirmed this and also reported a previously concealed guarding effect by tourist groups on an iconic seabird colony in the Baltic Sea. Triggered by the COVID pandemic, a halt of visiting tourists in 2020 led to a strong increase in presence of white‐tailed eagles but facilitated egg predation from herring gulls ( Larus argentatus ) and hooded crows ( Corvus cornix ).…”

This study aims at supporting the maintenance of representative functional habitat networks as green infrastructure for biodiversity conservation through transdisciplinary macroecological analyses of wet grassland landscapes and their stewardship systems. We chose ten north European wet grassland case study landscapes from Iceland and the Netherlands in the west to Lithuania and Belarus in the east. We combine expert experiences for 20–30 years, comparative studies made 2011–2017, and longitudinal analyses spanning >70 years. Wader, or shorebird, ( Charadrii ) assemblages were chosen as a focal species group. We used evidence‐based knowledge and practical experience generated in three steps. (1) Experts from 8 wet grassland landscapes in northern Europe's west and east mapped factors linked to patterns and processes, and management and governance, in social‐ecological systems that affect states and trends of wet grasslands as green infrastructures for wader birds. (2) To understand wader conservation problems and their dynamic in wet grassland landscapes, and to identify key issues for successful conservation, we applied group modeling using causal loop diagram mapping. (3) Validation was made using the historic development in two additional wet grassland landscapes. Wader conservation was dependent on ten dynamically interacting ecological and social system factors as leverage points for management. Re‐wetting and grazing were common drivers for the ecological and social system, and long‐term economic support for securing farmers’ interest in wader bird conservation. Financial public incentives at higher levels of governance of wetland management are needed to stimulate private income loops. Systems analysis based on contrasting landscape case studies in space and over time can support (1) understanding of complex interactions in social‐ecological systems, (2) collaborative learning in individual wet grassland landscapes, and (3) formulation of priorities for conservation, management, and restoration.

“…They hypothesized that cormorants switch foraging grounds when the preferred type or size of prey is more easily available there. In waterbodies with strong anthropogenic activity regarding traffic, recreational use, or hazing, birds might temporarily also move to less‐disturbed waterbodies (Velando and Munilla 2011, Chatwin et al 2013, Hentati‐Sundberg et al 2021). In addition, young birds, non‐breeders, and roosting birds are reported to roam a region and visit several waterbodies (King 1996, Rutschke 1998, Leib 2009).…”
