Totals of 115 pairs of Black-bmwd Mollymawk~Diomedea m mefanopbrys and about 20 pairs ofWhite-capped Mollymawks D. cautn steadi were estimated to be nesting. Based on previous counts from Bollons Island and population estimates horn other islands in the New Zealand region, we ~wnclude that numbers of D. m. melanopbtys have increased in his region, in contrast to D. m. impavida which has decreased. The few data on the population size ofD, cauta stead hint at a population increase in that taxon also.

Animal evolution is a kind of the accumulated memories of biological adaptions to the surrounding nature. Changing nature produces tremendous variations in biological kingdom.

Distribution patterns of such pores on ostrich (Struthio camelus) eggshells show remarkable variations in bird group. Eggshells preserved in the museum of New Zealand have long, superficial, winding grooves and ridges, with pores distributed densely in the bottom of grooves. Both the grooves and ridges that separate them are twisted. By contrast, the surfaces of eggs from farmed ostriches are mostly smooth, with only occasional, short grooves, and respiratory pores distributed more evenly. The cause of ridging and grooving of the surface of eggs from wild birds is unclear but may be due to the need for stronger shells and effects of environmental stresses. It appears that the arrangement of respiratory pores on ostrich eggshells seems to be changeable by surrounding stresses.
