Maison Budgerigar got an extension today. I bought a new cage, took out the sides, and joined the two cages together to form an extra long flight cage. Zumbador and Elmore spend most of their days out of the cage, but sometimes that's not possible and now at least they can stretch their wings a bit.
Zumbador, true to his dim but adventurous little self, was the first to explore the new space. Now the more cautious Elmore has settled in as well and they both seem contented. Lots of commentary from both, of course.
