Morphological characterization and the significance of sexual differences in size among Lipochromic Mosaic Canary bird raised in the Wilaya of Tlemcen Northwest of Algeria

The lipochromic mosaic canary is a cage bird breed present with different coat colors, red, and yellow, this presents significant sexual dichromatism. Dichromatism in canaries explained by differential carotenoid degradation the integument, rather than sex-specific variation physiological functions such as pigment uptake or transport. Males have an intense color compared to females especially at shoulders head. We studied size dimorphism (SSD) because study aimed investigate whether gender has impact on thirteen body measurements which are (Head Length, Head Width, Distance Between Eyes, Beak Chest Circumference, Body Wing Sternum Upper Tarsus Lower Tail Length) 40 native (19 males 21 females) raised Wilaya of Tlemcen Northwest Algeria. results showed that there were differences between genders for three characters CC (Chest Circumference), BL (Body Length), WL (Wing Length). had more developed measurable traits females.
