Abstract :

The following traits of Zebra Finch nestlings were considered: body weight, body length, plumage
development stages, wing-formula and length of wing, beak, tail and primary remiges. The study
was conducted on 12 nestlings obtained from parents of different colour varieties. Observations
were conducted from hatching to week 12 of age, i.e. when the nestlings’ plumage was already
typical of the adult birds. During the research period 47 eggs were obtained, from which 16 nestlings were hatched. The highest number of clutches was noted in the summer and autumn months. The values obtained for zoometric traits, indicate that nestlings maintained in captivity, compared to those living in natural conditions, showed a higher growth rate as well as a quicker plumage development. In a majority of birds the length of the body, wing, primary remiges and beak reached adult dimensions in week 7 of life, while body weight and tail length - in week 8. In turn, on the basis of morphological changes, it proved possible to determine in what order individual traits appear, to determine the sex and age of birds and to determine the plumage type and the wing formula.
