  We present multicolor photometry of bright star cluster candidates in the
nearby starburst galaxies NGC 3077 and NGC 5253, observed with the Hubble Space
Telescope Wide Field and Planetary Camera 2 in both broadband (F300W, F547M and
F814W) and narrowband (F487N and F656N) filters. By comparing the photometry
with theoretical population synthesis models, we estimate the age and mass of
each star cluster, which provides constraints on the recent star formation
histories of the host galaxies. We compare the star cluster populations in
these dwarf starburst galaxies to those of the nuclear starburst in the barred
spiral M 83, and discuss implications for our understanding of the nature and
evolution of starburst events.
