Gross anatomical structure of pelvic bone in conure bird was studied. The shape of the pelvic girdle was in the form of inverted blade and consisted of ilium, ischium and pubis, constituting the two pelvic bones of which the ilium was largest and between the two pelvic bones, the rhomboid shaped lumbosacral mass was observed. Above the level of acetabulum ilium was separated by a small bony ridge as pre and post acetabular part. Posterior end of ilium had a slender, linear and extended part and had a straight process which projected ventrally. There was no ilioneural canal. Ilium, ischium and pubis formed the acetabulum. The caudodorsal rim of acetabulum presented a triangular facet an anti-trochanter. Ischium was a thick and triangular bony plate below the level of posterior rim of the acetabulum. Ventral border of the ischium had an obturator foramen with broader caudal end. Ilium formed synostosis with pubis and ischium and a large ischio-pubic notch were also formed. Pubis was thin , slender bone extended behind the medial border of ischium. Ischium was bent posteromedially. Pubis was not fused with ischium to form obturator foramen, but formed a notch-like structure. The pectineal process was less developed.
