Results of a comparative geographic analysis of 3 dimensional characters (in males) and of plumage (in both sexes) in sympatric populations of the House sparrow, Passer domesticus, and of the Spanish sparrow, Passer hispaniolensis, collected in February and March in western Algeria. Tail length shows a significant geographic variation in males of both sparrows, and wing length in males of Spanish sparrow. Coincidence of geographical variation in feather dimensions of the two taxa suggests a parallelism, owing to common environmental pressures. Plumage colour of the House sparrow varies geographically : on that account the specimens collected in Bechar oasis differed from those examined in northern localities.
