  <dc:description>Color of Black-crowned Night-Heron (Nycticorax nycticorax ) eggs of known laying order was quantified  in a Wisconsin colony. Eggs were of greener intensity on the day of laying and one day thereafter than earlier  laid eggs within a clutch. Egg color can be used to identify clutches within one day after clutch completion and to  assign laying order within clutches during this period.</dc:description>
