Hi Greg, > I know I wasn't invited but I peeked anyway. Were these two birds of opposite sexes? I don't see any difference between the two birds. Do you or did John notice any difference? They certainly cooperated well for the reflected UV shots. Yup ... that was the hope of the owner of the birds - a devoted caique parrot owner. But, alas, there sure did not appear to be any difference under any lighting/visualization "regime" between one bird and the other. Maybe if you looked at the photos wearing sunglasses you might see a difference! :) cheerio, andy
