Sažetak

Using Maple V we compared the data of original bird-eggs given by Jacab with the theoretical results given by Wunderlich. It turned out that for the eggs of the bird Sterna hirundo the parabolic cubic and the Kirste profile seem to be almost identical, and their plots coincide with the curves drawn by oologists. But, for the eggs of the birds Sterna paradisaea and Sterna dougallii differences are greater.
