Symposia provide an opportunity to bring together invited experts to share their results and experience related to a new or timely topic in ornithology. The talks within a symposium should be focused around a central theme and allow for thorough coverage of that theme. Organizers may request half- or full-day sessions; morning sessions include six 15-min timeslots, afternoon sessions include twelve 15-min timeslots, and all-day symposia include eighteen 15-min timeslots. Talks should be multiples of 15-min and each symposium may include a summary or panel discussion in its final 1–2 timeslots.
Lightning Symposia consist of pre-timed 5-min invited talks that address a common theme/question in ornithology. The organizer(s) of a lightning symposium will ensure that all talks are preset to 5-min with slides advancing automatically.
