Dr. Kees Camphuijsen

Senior Scientist

Birds and mammals as part of a large jigsaw puzzle

Marine ecologist Kees Camphuysen obtained his PhD for his long-term research into the herring gulls and lesser black-backed gulls in colonies on the island of Texel. ‘These birds’ lives are strongly related to commercial fishing activities on the North Sea. The development of the chicks is synchronised with commercial fishing efforts in the vicinity. For example, the chicks scarcely grow on a Saturday or a Sunday, and cannibalism is high if the fishing boats are in harbour during weekends. Alternative sources of food, of which there are many, are insufficient to stave off this weekly recurring starvation. For the herring gull, there is a strong relationship with food supplies in cities. Since we have covered up landfill areas, somewhere in the 1990s, herring gulls turned their attention to our villages, towns and tourist centres. Natural resources are insufficient to maintain the populations which increased so strongly in the past. Consequently, the number of herring gulls has been decreasing for many years.’

Nuances of the North Sea

‘Ultimately, this sort of puzzle is just a small part of a far bigger picture. Research into birds requires a proper understanding of their environment, but also of their relations with other species. In our current research in the North Sea, we are trying to map and quantify all of those complex connections. This concerns interactions between species – many birds and sea mammals are mutually dependent in their search for food – but also the characteristics of the areas they forage in. Not everything that floats on the North Sea is water. Salt concentrations, depth, currents, seabed fauna and visibility are just a few of the factors that determine why one location can be highly suitable for a species, while another is not.’

Using birds to take a look below the surface

‘It is highly tempting for a biologist to use transmitters and other high-tech equipment to study not just one species but even a limited number of individuals. However, you then risk losing sight of the bigger picture, notably the species interactions. By no longer viewing bird research independently of the environment and the interactions between different species, we understand more about the impact of human interventions, such as the construction of offshore wind parks or offshore islands. As research below the water surface is relatively difficult, we combine seagoing research of the clearly visible birds and seals, for example, with demographical studies in their colonies or roosts on land. By simultaneously measuring their “performance” on land (e.g. survival, number and growth of the young), we hope to learn more about the quality of their living environment at sea.’

Interests

Research interests

Marine studies and research interests (1984-present) include at-sea work in the Atlantic Ocean, studying offshore distribution patterns, ecological interactions and interactions with fisheries of charismatic megafauna (whales, dolphins, turtles, seals, large predatory fish, and seabirds). Areas of research include the Greenland Sea, Norwegian Sea, North Sea, Atlantic Ocean, NW African shelf waters, SW African shelf waters, South Georgia, South America, and the Antarctic Peninsula.

Seabird colony studies on the foraging ecology, demography and migratory movements of Herring Gull Larus argentatus and Lesser Black-backed Gulls Larus fuscus. Colony work commenced in 2005, colour-ringing programmes and diet studies since 2006, and GPS tracking since 2008.

Studies of marine oil pollution since early 1970s through systematic beached bird surveys within The Netherlands and impact assessments of major oil spills throughout Europe.

Recent research interests in collaboration with the Netherlands Institute for the Study of Crime and Law Enforcement (NSCR) focus on Illegal, Unreported and Unregulated fisheries worldwide.
