In forests on the Southern Tablelands of New South Wales seasonal events within the avian community were tied to the annual cycle of cold winters and warm summers. Insect, carbohydrate and seed abundance changed with the seasons and were tracked by the avifauna. Superimposed were events determined on a larger regional scale. Irruptions of birds from the arid interior and drought caused significant, if transitory, changes in the forest avifauna. This has implications for the conservation and management of forest ecosystems
