Effects of mast seeding on forest bird communities

Forest habitats are frequently characterized by synchronized and intermittent production of a large seed crop (mast seeding). These “resource pulses” trigger a cascade of direct and indirect effects that permeate throughout forest ecosystems and have critical consequences for forest communities, including birds. We investigate how ecological and life-history traits affect the way birds respond to mast seeding, and how mast seeding affects nest predation in forest songbirds.
