Resumo
Numida meleagris (Linné, 1758) is an african bird that was brought to Brazil. As the bird adapted to the climate of this new habitat and spread ali around the country, it is nowadays part of our avifauna. The present study continues topographic and morphofunctional researches on the female genital apparatus of this species, since it describes histological and histochemical aspects of magnum, a segment of oviduct. Magnum was dissected and processed according to routine and histochemical staining procedures to detect glycogen and mucous substances in the epithelial tissue and mucous glands. Besides focusing morphological aspects, the study compares the data obtained with those of other species aiming to contribute to the enlargement of the knowledge on reproductive biology of brazilian birds what may be important to make their biological control easier.
