GOS is a charity. Donations are welcome and it is only £12 to join (for which you get the annual bird report, email updates concerning events and an invitation to attend all of our walks / field trips free of charge). Walks are £5 for non-members. We welcome members and non-members alike to the free online talks. For in-person talks there is a nominal fee of £1 on the door to help cover room hire.

We encourage all to join the society and contribute to the bird recording and conservation initiatives GOS promotes.
