We present an analysis of 109 moderate-luminosity (41.9~0.8 preferentially have bluer (rest-frame U-V2.5) galaxies have the highest fraction of AGN (21%) in our sample. We explore the scenario that the evolution of AGN hosts is driven by galaxy mergers and illustrate that an accurate assessment requires a larger area survey since only three hosts may be undergoing a merger with timescales <~1 Gyr following a starburst phase
