12Habitat and BiologyGreat Bustard seeks a mate...Great bustards do not live in pairs, but in breedingcommunities (internationally know as “leks”).This can consist of up to 130 animals and take ina area of between 30 to 80 square kilometres.Outside the breeding period the adult bustardstend to live in groups split by gender, but theyoung of the last brood remain with the femalegroups. Males and females find one another primarilyin the courting period.The birds return to the same place every year forcourting; as a rule these are spots that have beenused for generations.Cocks skirmishingat the edge of thecourting ground.
Habitat and Biology13The courtship is an incredible sight. The cocktransforms himself into a large, white ball of feathers– to do so, he turns the brown, patterned flight feathersout so that the white underside and the whitefeathers of the elbow face upwards. The tail flipsup to the back and shows only the white down feathers.The long beard feathers stand straight up. Thetransformation is swift and complete. The puffed upneck makes the cock seem even bigger. Easily visiblefrom afar the cocks attract receptive females at agreat distance. In small, isolated groups the hens flyover 10, sometimes even 30 kilometers, to reach thecocks at the next breeding ground. To brood theyreturn to their familiar territory, as the cocks haveno duties during the brooding and upbringingtimes whatsoever. It was previously thought that thehens usually bred within a five kilometre radius ofthe mating ground. According to the latest resultsfrom Spain, the breeding grounds are on average8 kilometres from the mating ground, but can beup to a maximum of 54 kilometres away.The choice of partner is made by the hens. Theychoose one of the strongest cocks for the fertilizationof their eggs. For this reason the older hensare more likely to procreate.Did you know...during the courtshipthe heart rateof the cocks canreach 900 beatsper minute?
