The ontogeny of this species was divided into three phases: Embryonic development of Columba livia Aves: Th is paper describes the changes and cellular events involved in the formation of the follicles of Columba livia. Post-ovulatory females were found from March to June and most females had oocytes at different stages of maturity, with abundant post-vitellogenic oocytes from August to December.

The species showed sexual dimorphism in body mass, with females larger than males. We analyzed the histological constitution of testicles of embryos from the stage E. During ovarian ontogeny of birds can recognize five key events: Th e knowledge of these events is crucial for the interpretation of the processes involved in the diff erentiation of female gametes.

Stage II is characterized by the initiation and meiotic arrest of prophase and primary oocytes. The late phase stages shows the overall embryo growth, the final organization of the conetitucion pattern and growth of feather germs, as well as final consumption of the yolk, and hatching.
La ontogenia de dicha especie fue dividida en tres etapas: In stage I the oogonia nests are grouped surrounded by a layer of pre follicular cells.
