Sumario:Seasonal variations of the structure of the Spotted Tinamous ( Nothura maculosa ). Morphological data obtained by means of observation under optic microscope in ovaries of the Spotted Tinamous.(Nothura maculosa ), are presented. The characteristics of the ovaries in winter recess and in time of breeding activity are compared. In the first period it is noticed the very redueed size of the organ; small follieles; numerous masses of folicle atresia and groups of vacuolated cells (full of lipids). In the second period the ovaries are well developed, the rate of follicle growth has increased, and active vitellogenesis takes place a minor number of atresic follicles and of masses of cells full of lipids are observed. These characteristics and some less relevant ones are described and its significance is briefiy discussed.
