sometimes oviduct is used interchangeably with follaopian tube. Here they are different - the oviduct connects the gonad to the outside in a variety of animals. The mammal-class fallopian tube is derived from the mullerian duct and connects the gonads/infubdibulum to the uterus

A passage through which ova leave the maternal body or pass to an organ communicating with the exterior of the body. [TFD][VHOG]

In all remaining vertebrates (i.e., coelacanths, lungfishes, amphibians, reptiles, birds, and mammals), the oviduct arises in ontogeny as a longitudinal, groovelike invagination of the coelomic epithelium on the lateral surface of the mesonephros.[well established][VHOG]

in birds divided into infundibulum, magnum, isthmus, uterus, and vagina, The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity. The fish eventually extrudes the eggs through small genital pores towards the rear of the body[WP]
