c) Smithsonian Grid to Oahu 
After leaving the Grid on 21 August, diurnal observations and collecting 
of birds were carried on from the morning of 22 August until the evening of 
25 August* Honolulu was reached early the following morning (26 August)* A 
total of U6l miles and 5>0*2 hours were covered during these observations; 3,538 
birds of 2k species were noted* A brief stop was made during the afternoon of 
22 August to put a crew member of the SHEARWATER ashore on Johnston Island* 
21 specimens of 6 species were collected, 10 of these Pterodrcma * This phase 
of the cruise included slight deviations from a direct course to Oahu for the 
purpose of collecting specimens, especially petrels* All specimens collected 
during the cruise, except Newell’s Shearwaters and Pterodrona sp*, were prepared 
as skins during this time* These later were frozen for preparation in Honolulu* 
Pelagic Work Inside Grid 
Diurnal observations and collecting began at sunrise on 16 August and 
continued until sunset on 21 August# A total of 658 miles aid 75*5 hours were 
covered during these observations; 8U9 birds of 15 species were recorded* 23 
birds of 8 species were collected* Ectoparasites and blood sera samples were 
collected when appropriate on all specimens* Moderately rough weather combined 
with a scarcity of large flocks prevented the use of the small skiff for 
collecting* On the morning of 21 August (6th day in Grid) it became necessary 
to take a crew member of the SHEARWATER to Johnston Island* The westernmost 
leg of the Grid was not run* Instead, a direct diagonal course to Johnston 
was followed* The usual observations and collecting were continued while 
in the Grid area* 
Island Work 
Lays an 
Landed on island at 1530 on 5 August and set up camp* The nights of 5-H 
August were spent primarily on banding operations* A limited amount of diurnal 
banding was done* A total of Uii,l*i|2 birds of 8 species were banded; U0,00 of 
these were Sooty Terns* Succeedingly longer periods of bright moonlight each 
night of the survey seriously hindered banding operations* 29 returns of 7 
species (including 6 orange-streamered Sooty Terns) were recorded* 5U recoveries 
of Laysan Altatross chicks were collected. 97 blood sera samples of 9 species 
were collected on the night of 12 August prior to departure from the island. 
A total of 812 birds of 11 species were checked for tick incidence, of which 322 
were found positive (IJ 4 of these were Ixodes )* Nearly 9&% of the infested birds 
were Sooty Tern chicks* 210 Hawaiian Monk Seals were recorded during a con¬ 
centrated survey made on 6 August. Population estimates and breeding data were 
taken throughout the survey. 23 species of birds were recorded on the island; 
13 of which were in some stage of the breeding cycle. Special attention was 
given to counting Laysan Teal during the survey, but only about 15 birds (includ¬ 
ing two 3/k grown ducklings) were recorded. Berlese samples of the canmon 
breeding species were collected. House flies were encountered in great numbers 
over the entire island and seriously hindered diurnal operations# Party departed 
island at 2IDO on 12 August and boarded SHEARWATER.
