Plenary Lectures are keynote addresses by outstanding ornithologists.
Symposia are aimed at the general ornithologist and will provide the widest-possible coverage of current ornithological studies. Each symposium will feature five papers invited by the conveners. Oral contributions will be selected by a Review Panel of the Scientific Program Committee from the abstracts submitted. Round-Table Discussions are a forum for discussion on specialist topics, covering new scientific findings, and new directions in a particular field, methods, techniques and hypotheses. Special Interest Groups may arrange to meet during the Congress.
