'Bird' chapters were formed with lone travellers in mind, but under the constitution of the CMCA any member may join. They are similar to the Solos Network in nature, but they are locally based, whereas the Solos Network is nation-wide. The bird chapters (usually) have monthly gatherings, lunches, and morning teas, while the Solos Network has just two rallies per year.

They are all named after birds, because :

To be a Solo is to be as free as a bird.
