Abstract: The gathering and analysis of field data on various facets of bird life is thought to be essential for the advancement of ornithological study. The Oriental Magpie-Robin is renowned for its distinctive and beautiful vocalizations, although research on it is extremely underdeveloped. This study aims to comprehend the gross and microscopic anatomy of the tropical songbird Oriental Magpie Robin (Copsychus saularis). It is the national bird of Bangladesh. It is a medium-sized passerine bird where males have a white and black combination of plumage and in females, the black part is replaced by grayish brown. This study showed that it is smaller in size and weight. Some similarities and dissimilarities have been found with other birds throughout the whole study. Some important organs like the trachea, lung, heart, small intestine, large intestine, and ovary were emphasized during the study period. This study also provided proof of its having syrinx on the base of the tracheal bifurcation for which it is known as a songbird. Investigation of lungs, and heart showed similarities of histological aspects with other birds like chickens, Iraqi pigeons, etc. Ovarian follicles provided information on atretic follicles that matched with the data found on laying hens. Aspects of histology of the intestine showed a resemblance with the data found on the English sparrow which is also a passerine bird. This work may mark the start of a new phase in the study of Oriental Magpie Robins. It can largely assist our doctors and conservationists in taking further actions for the diagnosis of diseases and observing the conservation of this species. If not, the population of the species will begin to decline, which may lead to an ecological imbalance.
