Chapter
This chapter collates the scope and limitations of technology and methods to quantify the density, identity, flight height and behaviour of bats and birds in the offshore environment, including both seabirds and migratory landbirds such as passerines and waterfowl. Such information is needed because offshore wind-farm development has reached the in...

Departure decisions of how and when to leave a stopover site may be of critical importance for the migration performance of birds. We used an automated radiotelemetry system at Falsterbo peninsula, Sweden, to study stopover behaviour and route choice in free-flying passerines departing on flights across the Baltic Sea during autumn migration. In ad...
Chapter
Most birds migrate at night and may be at risk of colliding with artificial structures that protrude into the open airspace. Collision risk assessments concerning offshore windfarms have been routinely based on discontinuous observations from ships. Dedicated avian radar systems installed close to the operational offshore windfarm alpha ventus, how...

... Out at sea, there are several methodological, technical, and/or logistical challenges to monitor bird migration (Molis et al. 2019). One major challenge particularly concerning songbirds, is their predominantly nocturnal migration (e.g. ...
... Several radar systems have been used in the context of bird detection at wind turbine installations. A first example is the bird scan radar proposed in [4] which is used to monitor bird migration through a wind farm. In addition, Wasserzier et al. [5] demonstrated bird monitoring in wind farms. ...
... In conclusion we would like to emphasize that our data and the data of other studies Taylor et al. 2011;Smolinsky et al. 2013;Mitchell et al. 2015;Deppe et al. 2015;Sjöberg et al. 2015;Dossman et al. 2016;Brown and Taylor 2017;Wright et al. 2018;Gesicki et al. 2019) show that before crossing ecological barriers and on coastal areas at least some songbird migrants perform regional-scale movements, not necessarily in the migratory direction. Involvement of migrants in such movements may strongly vary between the species, and also between age groups within the species, and also be conditiondependent. ...
