Abstract
The fatty acid and alcohol composition of the uropygial gland wax from four species of birds of the order Laro-limicolae was investigated. Compounds were identified by GLC-MS and the major components were found to be mono-, di and tri-methyl-branched fatty acids and n-, mono- and di-methyl-substituted alcohols. The wax patterns of the three species of the family Scolopacidae ( Tringa totanus L., Calidris canutus L., Calidris alpina L.) were shown to be closely related and different from that of the oystercatcher ( Haematopus ostralegus L.) by the occurrence of trimethyl-substituted fatty acids and dimethyl-substituted alcohols. In contrast to the species of Scolopacidae, the substituents in the monomethyl-branched alcohols of the oystercatcher are exclusively located in postions near the aliphatic end of the molecule. There are some relationships in uropygial gland wax composition between the Scolopacidae and the Alicae and Laridae.
