Lisianski Island
Landed on the island around 9 am in the Whale boat. Spent
until 1:30 p.m. making a complete island circuit with Jim +
Ernie in orde to census and tag seals + turtles. Returned to
camp and ate a quick lunch before shelving out to measure eggs.
The thick growth of Scaevola make walking a chore,
especially when combined with the large number of cheiranthus-petrel
burrows on the island. The soil on this island is the finest sand
I've encountered on any island and the burrow cave in easily. Normally,
as light as I am, I can skirt across the tops of burrows without
caring for many of them. This was not true on Taroa and certainly
isn't true on this island. About halfway across the island a
burrow caved in while I was measuring a Red-footed Booby egg and
I cracked my knee against one of the Scaevolas. The knee turned
black + blue almost immediately but didn't hurt very much.
Since it was we were scheduled to leave the island at 5:00 pm
there wasn't time enough for a complete survey of the island or
anything more than a cursory check of the various bird populations.
In the 3th channel I barely managed to run a fairly decent survey
of the southern half of the island.
Saw several seabirds but couldn't capture them - both
Red-footed Boobies.
The whaleboat returned at 4:30 pm instead of at 5 pm
as scheduled so I was unable to get one the 12 sets of Blue-
faced Booby eggs measured. During the 3 hours I was able to
get measurements of eggs + nest dimensions of: 17 Hawaiian Nody,
20 Great Frigates, 20 Grey-b. Tern, 18 Red-footed Bool., 13 Blue-
faced Booby and 1 Fairy Tern. Had to check over 200 nests for these
measurements. The majority of Red-footed Soobies were on nests but
only 18 kinds of 85+ nests chiled, had eggs. Had to check 60
Great Frigate nests to get 20 egg measurements.
As with other island populations, on the trip, we are a little
too early. Most birds are on fresh & barely incubated eggs. Sooty
Terns are swimming but not down during the day. The Blue-foot Boobies
are the exception to this statement. On Lisianski we found one large young
and four(4) small downy young in addition to four nests with
small naked chicks.

Lisianski Island
Vegetation was fairly lush. Erogrostis, Potalea and
Tribulus were all in full bloom. The Ironwood trees and
dense growths of Scaevola were in good condition as were the
two coconut trees (we drank the milk from two coconuts + planted
another).
During the island circuit we found several very small
turtles which we tagged. These turtles could be easily
picked up + carried by one man. Aside from the several we tagged
another five or six of similar size were observed in the water.
We saw no sharks around the inside reef nor did John and
Dick who did a great deal of diving in several areas. When we
returned to the ship we learned that there had been what they
described as "two hundred" around the ships. At least 25 had
been shot with an M-1 rifle and had been seen to sink. The
crew of the ships seemed to have enjoyed this.
We were back on the ship by 5:10 pm and heading for
Pearl + Hermes by 6 pm.
Sacked out at 8:15 p.m.
