Many of us often complain about excessive byrocracy related to breeding of animals. Fortunately, we are still not told in how big cages our birds should be kept. In Germany, breeders have to respect such law since 90s and the rule is specific for every region. Aviaries should always have the ratio of length and width 2:1 so birds have enough space to fly. The second important parameter of this regulation is minimal size of the inside and outside part.

In the following table you can check sizes of aviaries which are required by law in German region Thüringen. This information come from the regulation which has been effective since 2005. Authorities consider even the case when more species are bred in one aviary or when fledged youngers share the cage with their parents. When you want to add an extra bird to your aviary then it’s necessary to enlarge the space about the certain size (see the chart). For example when you want to add one extra macaw then the enlargement of 9 square meters is necessary. Minimal size for a breeding pair of budgies is 3 x 1,5 x 2 m (length x width x height). Bigger macaw species like Hyacinth macaws require 6 x 3 x 2,5m.
