Mammals i The island was overrun with cats which were feeding on all small birds 
as well aw frigates and a few Rod-footed Boobies* We killed 211 or about 80 
percent of the population* 
Mummified mice were found in the building but evidently the cats have eliminated 
the mice or at least reduced the population to a very few individuals * 
Reptiles i A few gekkos were collected. These are uncommon, probably because 
of cat predation. Turtles were seen off shore on days of arrival and departure. 
Insects s Approximately 250 specimens of 19 insects species were collooted, 
as well as a number of other Arthropods. 6 Berlizi samples were run. 
Usual complete coverage of all habitats* 300 plus live ticks were collected £n
