Multiple non linear regression model for the maximum number of migratory bird types during migration years

Since many years scientists have carried out researches about bird migration, but due to the large number of bird types estimated at around 10,000 in the world, it is not easy to predict the maximum number of migratory bird types through limited number of migration years. In this study, a multiple non linear regression model of maximum number probability function of migratory bird types has been obtained and can be used in the prediction of the maximum number of migratory bird types during any migration years.
