Directional parameters determined in the single orientation experiments are the starting point in the modelling of the common directions in the group of birds. Bayesian statistical 3-step method of the common directions number and parameters estimation is presented. The method is based on the marginal probability distribution of the single-test directions. Maximum Likelihood and Bayesian Information criteria for the proper model selection are used in each step. Computer program for the orientation modelling aid is also presented.
