Rusenski siv (mavija)
Blue Tumbler Rousse – or also known as: Maawi de Russé Culbutant, Russer Blauer Tümmler, Capitombolante di Russé Blu, РусиаСинийТурман – is a variety that comes from the Rouse region (northeastern Bulgaria), which was known before the 18th century . Varieties belonging to this type of Tumbler initially had very good flight ability, but were informed that the cultivation touches made so far had exacerbated the ability to fly. Actually this variety is quite popular, but it seems only limited in some countries around Bulgaria. Now, this variety is more commonly known as pigeon display.
