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.
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.

Combining remote sensing and tracking data to quantify species’ cumulative exposure to anthropogenic change
The results showed that although the actual amount of change had been greatest on the breeding grounds, cumulative exposure to changes in direct mortality risk and climate were highest during the Cuckoos’ autumn migra
West African stopover determines timing of Cuckoo arrival
The authors use 11 years of satellite tracking data from 87 male Cuckoos, tagged at 11 sites across the UK, to examine variation in migratory timing throughout the annual cycle and its potential consequences.
