Аннотация: Fatty acid (FA) contents and compositions in the pectoral muscles of 18 bird species from Novosibirsk, Volgograd, and Yaroslavl oblasts were studied. Three groups of birds that had significantly different FA compositions were distinguished based on a multivariate statistical analysis: Passeriformes, Columbiformes, and a group of waterfowl and waterbird species (Charadriiformes, Anseriformes, Podicipediformes, and Ciconiiformes). The highest content of physiologically important docosahexaenoic acid (22:6n-3, DHA), which is considered a marker of aquatic food, was surprisingly found in the biomass of Passeriformes, which are terrestrial feeders, rather than in the biomass of waterfowls and waterbirds. It was suggested that Passeriformes species had the ability to synthesize large quantities of DHA from short-chain omega-3 FAs, which is rare among animals. © 2016, Pleiades Publishing, Ltd.
