Phenology is the study of the seasonal timing of life cycle events. You are studying phenology when you record the date a certain plant grows, a tree's leaves emerge, an insect hatches, or a migratory bird appears on its nesting grounds. Factors such as daylength, temperature, and rainfall influence the dates on which events occur each year.
