Terns, (Sterna spp. and Sternula albifrons), especially when on their breeding grounds, have emerged as sensitive receptors in many consented and planned OWF projects. To date, information on the interaction of terns with OWFs has remained scant due to a lack of understanding of the foraging ecology of terns especially at specific sites and the inability of standard assessment tools to define the relative use of specific areas by foraging terns. The current project aimed to advance the use of a series of methodological and assessment tools, some of which were initially developed in the Greater Wash SEA area (funded by Centrica/AMEC) with others developed specifically in this project. In essence, this involved a move towards an individual-based approach.

In essence, this involved a move towards an individual-based approach. Techniques included: 1) the development of visual tracking of foraging birds from colonies using a high-powered rigid-hulled inflatable boat (RIB – Fig. A), 2) use of both observation at colonies and boat-based colony transects immediately offshore of a colony to estimate flight bearing and passage rate of outbound and inbound birds, 3) development of individual-based simulation modelling to determine foraging patterns of birds derived from flight bearing and distance relationships, 4) detailed observation of type and rate of provisions delivered to chicks, 5) development of a energy balance model to predict the optimality of different provisioning strategies for both chicks and adults and how far adults could travel from colonies in energetic terms and 6) the use of data generated by visual tracking in collision risk modelling.
