Counts of galaxies within radii of 400 and 800 kpc around 13 head-tail radio sources located in the directions of rich clusters of galaxies are presented and used to search for a possible correlation between the galaxy distribution within the cluster itself and the orientation of the tail without the need for a well-defined cluster center. The overall galaxy counts are examined together with the locations of individual bright galaxies. It is concluded that there is little positive evidence in favor of a preferred orientation of the tails of head-tail sources with respect to either the cluster galaxy distribution or the location of nearby neighbors. These results are shown to be consistent with models for head-tail sources in which the parent galaxies ejected radio-emitting clouds while moving at high speed through the intracluster medium in directions that appear random in projection.
