I am using statistical modelling to try to understand the demographics of the roseate tern metapopulation in northwest Europe.
This involves using data on colony counts, breeding productivity and capture-mark-recapture (resighting) to estimate rates such as survival and movement between colonies and how these vary with age.
As part of the same overall project, I am also analysing tracking data collected by GPS tags and visually tracking terns by boat.
I have also investigated the effect of changing food availability on northern wheatear behaviour, productivity and survival with field experiments and run a monitoring and research programme on red and grey squirrels.
