Offshore wind - birds on migration in Scottish waters: strategic review
A report detailing the migratory routes of bird species around the UK and Ireland which have the potential to be impacted by offshore wind developments. This forms part of the strategic study of collision risk for birds on migration and further development of the stochastic collision risk modelling tool work package one.
Glossary
Abmigration: A summer migration made by a bird that did not make the reverse journey the previous autumn. In Europe this is usually a northward migration. It is observed most frequently in duck species, e.g., when resident birds pair up with wintering birds from elsewhere and then migrate with them.
Airspeed: The speed of a bird relative to the air. This will be the speed of the bird once corrections have been made for wind speed and direction.
a.s.l: above sea level.
Geolocation Tags: Tags which estimate the location of a bird using daylength to estimate latitude and time of mid-day relative to Greenwich Meantime to estimate longitude.
GPS (Global Positioning System) Tags: Tags which record the location of birds at regular (or in some cases, irregular) intervals with reference to the Global Positioning System. These data are stored by the device and recovered either through retrieval of the tag or, through transmission to a base station or over the mobile phone GSM network.
Groundspeed: The speed of the bird relative to the ground, i.e., the time taken for a bird to travel between two xy points, regardless of wind speed and direction.
PTT (Platform Transmitting Terminal): A satellite tag which is a small transmitter and sends messages to a dedicated satellite system
