We have investigated the stellar content of the blue compact dwarf galaxies (BCDG) Tol 0610-387 by combining near infrared and optical images, complemented by spectroscopic data. The color maps, combined with the Hα image allowed us to identify clusters possibly dominated by red supergiant stars (RSG) associated with the current ongoing starburst episode. The analysis shows that the local colors and Hα emission, when compared with the predictions from population synthesis models, are consistent with an aging stellar population of around 10-15Myrs dominated by red supergiant stars. This galaxy could therefore become a preferred target for the spectroscopic confirmation and analysis of its RSG population. Since the presence of such stars in BCDGs is seldom observed, we discuss the implications of RSG detection for the study of the starburst dynamics and evolution.
