Abstract
Color of Black-crowned Night-Heron (Nycticorax nycticorax) eggs of known laying order was quantified in a Wisconsin (USA) 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.
