🔥 MEET OUR NEW G&H CALIS ACQUISITIONS
Elite Dutch performance blood — proven at national & Olympic level
Some bloodlines don’t follow trends.
They define them.
With these new acquisitions, Burggraaf Global strengthens its foundation with direct performance genetics from G&H Calis — a loft that, in record time, stormed to the absolute top of Dutch pigeon racing.
National championships.
Olympiad pigeons.
A dynasty built on results — not reputation.
Between 2019 and 2024, Gerard & Harold Calis created one of the most dominant performance periods in modern Dutch racing, producing an extraordinary series of National Ace Birds, Olympiad representatives, and mass winners at the highest level. Their pigeons didn’t just win on their own loft — they became cornerstones on leading lofts across Europe.
At the heart of this success lies a powerful breeding base:
Sangers × Koopman × Verbree, reinforced by elite influences such as Staron (Gebr. Leideman) and, above all, the legendary Vale Bulck — direct from Marcel Sangers’ immortal Angelina.
A hen that shaped generations of NPO winners, National Ace Birds, and Olympiad pigeons.
What we selected is not volume —
but genetic certainty.
These are pigeons bred from winners, proven through generations, and selected to carry performance forward.
