Résumé : | Bearded Vultures Gypaetus barbatus began supplying material to their nests on average 111 d (range 91-126 d) prior to laying . Males were signifr icantly more active that females. Heavy material (branches) was transported indistinctly in the talons or in the bill while lining (wool) was generally transported in the bill . 71% of the wool was recycled from remains fallen ; from other nests, probably due to the scarcity of this material in relation to its importance for insulating the egg and chick from the low winter temperatures . No inter-sexual differences were observed with regard to the type of the material selected or how it was carried to the nest . The early nest-building behaviour and the fact that the males were the most active builders are discussed in the context of maintenance of the pair-bond and female selection. After laying, material for nest-maintenance was only rarely supplied, suggesting high solidity of the structure at its location at protected sites . (Résumé de l'éditeur) |
