POBSP Man-days spent on Lisianski : 1.1 
During our very brief survey of Lisianski the primary objectives of 
the party were to count, tag, and return Hawaiian Monk Seals and Green 
Sea Turtles. The POBSP observer tried to obtain credible population 
estimates and to determine, so far as was possible, the breeding status of 
the species occurring on the island. 
A nearly complete count of the Blue-faced Booby nesting population 
was obtained and pair data were obtained for 14-2 birds. Hopefully, this 
data, when analyzed in conjunction with similar data taken in March 1965 
and June 1967, will provide useful data on duration of pair bonds that 
will supplement similar data taken on Kure. 
Three specimens were collected: a Sanderling, a Glaucous-wingeci Gull, 
and a hybrid Black-footed x Laysan Albatross. Fifty*-two birds of 2 species 
were banded and 165 returns were obtained from 7 species. Thirteen of these 
returns were Ruddy Turnstones obtained by other members of the survey party. 
Of these 13 returns one was evidently from Laysan and two had been banded 
on Lisianski. 
Vegetation on Lisianski appeared to be considerably more lush than 
on Nihoa, French Frigate Shoals, or Laysan, which may account in part for
