My research relates to the timing of seasonal events, such as breeding and moult, in avian annual cycles and the consequences of environmental change on this. Birds need to time their breeding attempts to coincide with the annual peak in food abundance. Breeding seasons can vary widely between species both in timing and duration and with latitude within species. Gonadal maturation needs to be timed appropriately. The annual cycle in photoperiod is the major environmental cue that birds use to control the time gonadal maturation and regression, yet breeding seasons are rarely, if ever, symmetrical with change in photoperiod. Moult also needs to occur when food is relatively abundant, but not at the same time as breeding or migration. Discovering the neuroendocrine and endocrine mechanisms involved is a key theme of my research. Understanding these processes is important when assessing the potential consequences of environmental change and the viability of mitigation strategies, such as moving to higher latitudes.
