IT also searched the Little Barrier Island for tuataras, but in vain. The 
large quantities of feral pigs living upon that island may easily account for 
their absence. There are also none on the Hen and the Guano Islands. Most 
frequently they were found by me on the large western Chicken Island. I 
believe that they are still more abundant on the smaller islands; however, 
although I tried repeatedly to land on them, the heavy surf would not allow 
me to do so.
