Thank you for your interest in competing in the BirdSO Invitationals! This year, we will be hosting two Division B/C tournaments, a Mini Tournament and a Satellite Tournament. The Mini Tournament, which takes place from the comfort of your own home, will run from December 11–18, 2021. The Satellite Tournament, which takes place at your school under the supervision of your coach, will run February 12–19, 2022.

Mini Tournament: December 11–18, 2021
Satellite Tournament: February 12–19, 2022

Regardless of which tournament format you choose to participate in, we strive to deliver the same high quality competition experience for which BirdSO is known.


Registration for the Mini and Satellite Tournaments opened on September 17, 2021, at 3:00 PM Pacific Time. Registration for the Mini Tournament will close on December 7, 2021 at 11:59 PM Pacific Time, and registration for the Satellite Tournament will close on February 8, 2022, at 11:59 PM Pacific Time. All teams registering after we have reached capacity will be placed on a waitlist for that tournament.

To register, please have your coach fill out the Google Form linked below that corresponds to the tournament(s) you are interested in. (If you are interested in both Mini and Satellite you must fill out both forms.) We will follow up with the coach whose contact information is provided to complete sign-up on the Scilympiad platform.

Payment of the registration fee is not required to secure your spot in a tournament but is required to compete. The instructions and deadlines for payments are listed below; we encourage you to pay at your earliest convenience to get logistics in order as early as possible.
