Daniel is a Research Ecologist and part of the Wetland & Marine Research Team. His work primarily involves fieldwork and data analysis contributing to seabird tracking and monitoring projects.
Interests & ResponsibilitiesDaniel has a broad interest in marine ecology with particular focus on the response of seabird species to changes in the marine environment. Within BTO, Daniel has worked on tracking projects assessing seabird behaviour and distributions in relation to environmental covariates and marine renewable energy devices. He has a particular interest in the impacts of novel marine renewable devices, including tidal stream turbines, on the marine environment and diving seabirds. He has a keen interest in improving the management of Marine Protected Areas (MPAs) targeted for seabirds, through improved knowledge of seabird foraging behaviour. He also has a background in using camera traps and visual observations to investigate seabird diet, kleptoparasitism, and nest predation.

A crowded ocean: the need for demographic and movement data in seabird conservation
To implement effective conservation actions, locally and globally, we need to quantify the importance of the multiple, often interacting, threats to seabird population growth rates.
