Eggs, appr. four (4) or five (5) : 28 x 20 mm, oval. The shell is smooth, glossy and particular to two colors, olive or buff; are rarely bluish; marked with small dots or splashes in different tints of brown, sometimes olive and dark brown. Incubation is assured by the female in the month of May and lasts between 17 and 18 days. The male nourishes the female. The young chicks are born altricial. Education of the young is assured by both sexes, but, it is the female that remains with the nest to protect the young. After five (5) days, the eyes open and after the 8th or 9th day, the feathers appear. They are ready to leave the nest approximately 17 to 21 days after hatching. They usually gain independence about 3 weeks later.
