Fifty-first Progress Report-Kure Atoll p 3* 
i 
Brown Booby- one adult bird from Pearl and Hermes Reef. 
Red-footed Booby- two from Midway* six from Sand- Johnston* and one 
banded on Kure but With an orange streamer* I believe that almost all the 
birds from Sand represent birds from the Kure population which roosted on Sand 
for a while and then returned. This can be seen from the bird banded here that 
had an orange streamer and another bird banded on Sand in February of this year 
that was found defending a nest here on 25 May. 
t 
Great Frigatebird- eight from Pearl and Hermes and one seen with an 
* 
orange streamer. Since the roosting areas for this species at Pearl and Hermes 
is very limited one would expect birds from there to travel. 
| 
Sooty Tern- seven from Midway including nne of Munro s 17 year lid birds 
three from Sand-Johnston, one from Pearl and Hermes, add one from Laysan. 
E. Population Discussion: 
The number of Laysan Albatross adults on the island has changed very 
little from last period. However, adult Black-footed Albatross are seldomed 
seen. Nestlings of both species are losing much of their down and starting to 
walk around a lot. Parents of the nestling are included in the population 
estimate, although they are seldom on the island. 
On 19 May I caught a Sooty Shearwater that was swimming in the lagoon. 
Its flight feathers were extremely well worn and it had little fat. Two more 
dead ones were found on the beach on 28 May. The last Bonin Island Petrel was 
heard on 25 May. No Christmas Island Shearwater nests have been found yet 
although they surely are present. 
The number of Red-tailed Tropicbirds over the island increased greatly 
this period with a maximum count of 473 on 21 May. Nesting activity also 
increased greatly. 
Nesting activity of Brown Boobies and Blue-faced Boobies increased
