Chris Hewson

Senior Research Ecologist

Chris is a Senior Research Ecologist in International Research Team where he works on the ecology and conservation of Afro-Palaearctic migratory birds and of forest birds across the world. Projects primarily focus of population changes, habitats and migration strategies of these species.

BSc (Hons) Geography, Nottingham University, 1989 – 1992 MSc Advanced Ecology, University of Durham, 1993 – 1994 PhD ‘Interactions between resident tits and migratory warblers in an English broadleaved woodland’, Dept. of Zoology, University of Cambridge, 1996 - 2000

Interests & Responsibilities

Chris is involved in all aspects of research projects on the status, ecology and conservation of Afro-Palaearctic migratory birds and forest birds across the world. Current and recent projects include tracking the migrations of Common Cuckoos through satellite-based radio telemetry, using geolocators to reconstruct the migrations of individual Common Swifts, Nightingales, and Pied Flycatchers, large-scale field surveys of migratory birds across a broad latitudinal transect from the Sahel to the moist tropical forest in West Africa, detailed studies of the winter ecology on migrants in tropical Africa and assessment of the biodiversity value of forests in western Siberia. Previously he has been involved in large-scale studies monitoring the population trends and habitat use of woodland birds in Britain, as well as smaller studies examining a range of processes thought to affect birds in woodlands, such as nest predation by Grey Squirrels and grazing by deer.
