Abstract
Basic external morphometric characteristics, along with a detailed colorimetric analysis, were studied in the eggs of eight Phasianidae species reared as ornamental birds in Bulgaria: Temminck's tragopan (Tragopan temminckii Gray, 1831), Satyr tragopan (Tragopan satyra Linnaeus, 1758), Golden pheasant (Chrysolophus pictus Linnaeus, 1758), Lady Amherst's pheasant (Chrysolophus amherstiae Leadbeater, 1829). Silver pheasant (Lophura nycthemera Linnaeus, 1758), Reeves's pheasant (Syrmaticus reevesii Gray, 1829), Grey peacock-pheasant (Polyplectron bicalcaratum Linnaeus, 1758), and Common pheasant (Phasianus colchicus Linnaeus, 1758).
