Conference Volunteers

We are looking for a dedicated group of volunteers to help make the American Ornithological Society & Society of Canadian Ornithologists/Société des ornithologistes du Canada (AOS & SOC–SCO 2023) a spectacular success! We are asking volunteers who are planning to attend the conference to work at least 10 hours total (including any required training) in exchange for $120 off of registration to AOS & SCO–SOC 2023. Learn more about this opportunity here!

Student Travel Awards

The AOS and SCO–SOC provide travel awards for students (undergraduate, master’s, and doctoral) as well as postdocs to help defray travel expenses associated with attending our annual meetings. Learn more about these awards programs. The application period for Travel Awards closed on 15 March 2023

Caregiver Grants

The AOS and SCO–SOC are offering grants to offset the extra costs incurred by caregivers (such as parents of young children or those providing elder-care) to attend the annual meeting. Any conference registrant is eligible, although priority will be given to presenters and early-career researchers. Applicants can apply for travel awards as well as Caregiver Grants. The application period for Caregiver Grants closed on 15 March 2023.

Funds may be used in any manner to support dependent care—to cover the cost of travel to the conference venue for an accompanying adult caregiver, the cost of dependent care at the conference venue, the cost of additional dependent care at home during the conference, etc. Applicants may also request caregiver grants to cover the Companion/Guest registration fee, which would allow the caregiver to attend all regular events at the conference. Funds cannot be used for conference registration or travel for the applicant.

Workshops & Training Opportunities

Workshops and training opportunities are scheduled on Tuesday (8 August). These fee-based sessions offer opportunities both for hands-on learning exercises, where participants engage in a mix of lectures and activities, and for panel discussions on a wide range of timely topics highlighting exciting advances in ornithological research, management, social justice, education, and conservation. Sign up for these workshops during the registration process.


Registration fees do not include accommodations. The AOS has reserved blocks of rooms at the DoubleTree London and the Delta London Hotel Armouries. To receive group rates, reservations should be made by the deadlines listed on the Accommodations & Travel Resources website page, which lists locations, details, rates, and cancellation policies for each of these hotels. Cancellation of hotel reservations and other accommodations are subject to the specific policies and booking deadlines for each hotel. Local transportation options are listed on the Transportation page of the conference website.

Field Trips

This year’s exciting field trips are being planned by the Local Planning Committee. We have organized birding field trips in the local area. Tours are available before, during, and after the conference. Registration for these field trips is open only to AOS & SCO–SOC 2023 Conference registrants; registration for field trips will be available soon. For details on these opportunities, visit our Field Trips page on the conference website (available soon).

Cancellation Policy

If you find it necessary to cancel your registration, we are able to refund your conference fee costs (less a $75 USD processing fee) if we receive notice on or before 30 June 2023. Refunds on registration fees will not be issued for cancellations received after 30 June 2023, except in cases of a documented positive test for COVID-19 in which the required self-isolation period precludes travel to or attendance at the conference. More information about this policy is available on our COVID-19 Information page. Current Government of Canada/Gouvernement du Canada guidelines and COVID-19 Travel guidelines will be followed for determining the required self-isolation period. Refunds will not be issued for “no-show” registrants for any reason. All refunds will be processed at the time of cancellation.

Cancellation Procedures. If you registered online, you can cancel your registration by submitting a cancellation request via the Google form. If you have questions about cancellation processing, please send an email to with the subject line: ‘AOS & SCO–SOC 2023 Cancellation Request.’
