Given the rarity of available researches on this bird species. The present study was aimed to assessing and comparative characteristic differences for important part of the respiratory system between males and females in indigenous Peacock (Pavo cristatus) through investigate and describe the anatomical features of the trachea in both sexes. In this study twelve healthy adult peafowl (6 peacocks & 6 peahens) were used after collecting them from a commercial market (Dyalla, Abo-Gareeb and Baghdad), to investigate and describe the anatomical and histomorphological features of the trachea in these bird species. The mean live weight was (3.49 kg. for female & 3 kg. for male). After euthanized they were killed by cutting of the major neck blood vessels and let them bleeding until death, trachea identified (shape, position, dimensions and general description of each specimen) and the measurement were recorded in male and female peafowl. The trachea looked as empty cartilaginous tube extend from cricoid cartilage of the larynx (rostrally) to the first tracheosyringeal cartilage caudally (syrinx), and composed of serial overlapping complete circular cartilages, each ring contained mostly two notch due to growth and overlapping. There were two paired of skeletal muscles that associated with the trachea (Sternotrachealis and Trachiolateralis. There is a significant difference in Tracheal length between male and female. This study was done at the department of anatomy and histology of the college of veterinary medicine, University of Baghdad/Abo-Gareeb.
