Abstract
The uropygial gland fat from the jackdaw, the carrion and the hooded crow are shown to be ester waxes. Chemotaxonomically the latter two are undiscernible. Their uropygial waxes consist of 4- and 6-monomethyl-, 4.6-, 4.8-, and 4.10-dimethyl- and 4.6.10- and 4.6.12-trimethyl- substituted fatty acids and n- (59.7%) as well as monomethyl-branched alkanols with branches in 4-, 6-, 10-, and 14-position. In contrast to the jackdaw they show no relation to the earlier investigated rook. The uropygial gland fat from the jackdaw is composed of n- (35.7%) and 2-methyl-substituted fatty acids (64.3%) and w-(87.5%) and 2 methyl-substituted alkanols (12,5).Keywords
