The present work was particularly designed to study the comparative anatomy of the skull of three different feeding Aves species inhibiting in Egypt. This study demonstrates that both size and shape are important components in the morphological differentiation of the skulls of carnivorous Kingfisher (Halcyon smyrnensis), insectivore Hoopoes (Upupa epops) and Omnivores Chicken (Gallus gallus domesticus) which clarify the relationship between size, shape of the skull and the type of feeding behavior. This paper presents a morphometric analysis of Kingfisher, Hoopoes and chicken skulls. Analyses are performed using traditional analytic and morphometric methods.
