The present study was conducted on the os coaxe of adult Indian eagle owl. The os coxae of Indian eagle owlconsisted of 3 bones namely ilium, ischium and pubis. All the three bones were fused and the space between the pelvicbones was occupied by lumbo-sacral mass. Ventrally, the bones did not unite with each other leaving pelvis open. Iliumwas divided into pre-acetabular and post-acetabular parts. The dorsal surface of pre-acetabular part was concave whereaspost-acetabular part was small and slightly convex. A very sharp and prominent crest was observed dorsally on eitherside of the lumbo-sacral mass. Anteriorly, the ventral surface of the ilium was flat and posteriorly, it presented renal fossafor the lodgment of the kidneys. The ischium was flat and somewhat triangular in outline. It formed a large sciaticforamen with ilium and a small obturator foramen with pubis. Pubis was a thin rib-like elongated bone situated along theventral border of ischium and formed ischio-pubic incisures with the ventral border of ischium. There was no pectinealprocess at the anterior end of the pubis. The acetabulum was circular in outline and in the form of a foramen. A largetriangular shaped anti-trochanter was observed in the caudo-dorsal aspect of acetabulum for articulation with trochantermajor of the femur.
