Griwuni Tumbler
The Griwuni tumbler, also seen under Grivun or similar spellings, is an eastern European tumbler pigeon name with Russian and German references in the fancy. It belongs to the tumbler and highflyer group rather than to owls or croppers. The name is associated with regional type and markings, and English documentation is uneven, so origin details should be treated cautiously.
Practical keeping depends on whether the family is flown. Performance-oriented Griwuni need careful settling, regular exercise, and selection for stable, recoverable action. Exhibition lines should still be kept active and healthy, with attention to color, head, body balance, and feather condition. Because transliterations vary, breeders should keep source notes and photographs. A buyer should not assume that a similar marked tumbler is the same breed without knowing the line's history.
