Contribution à l’étude des paramètres de reproduction de Moineau hybride (Passer domesticus x P.hispaniolensis ) dans la région de Biskra

Abstract

SUMMARY: We followed the breeding of the hybrid bird in two different locations from Biskra, Ouled Djellal (Station 1), Lotaya (Station 2) We recorded the presence of 8 nest at the level of surface holes (first station) and 8 nest on different types of trees (Station 2). The height of the nest is between 1.30 - 4 m and the area ranged from 866 to 354 - 324,99 cm² while the average number of eggs between 3-62- 4.37 eggs and the period of ovulation extended from 15 March until 16 April, while the period of egg break from 12 April to 9 May .. There is a positive relationship between The area of the nest and the number of eggs. The wider nest, which is located on the trees, contains more eggs. There is a negative relationship between the date of ovulation and the number of eggs . Early arrival of the hybrid bird can choose the broader nest and put the largest number of eggs . There is a negative relationship between the date of ovulation and the number of eggs hatched where we found that a large number of eggs hatched are those who placed at the beginning of the breeding season.
