We are interested in how parents manage interactions between the family and other species, and how these interspecific interactions drive selection on each member of the family.

We have a longstanding interest in the coevolutionary interactions between avian parents and brood parasites like cuckoos and cowbirds (Kilner & Langmore 2011).

But we are also interested in how parental diet during offspring provisioning can change key features of their developing young (Thorogood et al 2008, Thorogood et al 2011), which can persist into adulthood (Walker et al 2013a). For some species, this has important implications for their conservation (Walker et al 2013b).

Much of our current work focuses on how parents manage the microbial population that flourishes around the family (e.g. Cotter & Kilner 2010a, b) and whether associations between parents and phoretic mites and nematodes persist for this purpose (Cotter et al 2010).
