the relatively more advanced nesting cycles found in several species. 
The Iribulus was blooming profusely and the Eragrostle appeared consider¬ 
ably greener than on Laysan 
Black-footed Albatross Estimated breeding population — 1500-2000 
These albatrosses were not very abundant and apparently preferred to 
nest on the more open beaches of the southern third of the island. Only 
downy young were present. 
Laysan Albatross Estimated breeding population -- 4000 
This species was also not numerous and also appeared to be more 
abundant at the south end of the island. A number of old eggs were found 
but all active breeders had downy young. 
Black-footed x Laysan Albatross No. collected - 1 
At 1145 on 20 March I collected a hybrid by hand at the south end of 
the island just north and east of the cutbank at the southeast corner of 
the island. The bird was standing near an adult Laysan Albatross and both 
were near a young Black-footed Albatross in a nest near the rim of the 
Scaevola . This area was about 100 yards from a mixed Blackfoot-Laysan 
colony. A series of photographs of the soft part colors was taken the 
following morning. 
The specimen (Field #40809) was a male with the left testis measuring 
20 x 10 mm. It weighed 3039 grams of which at least 366 grams were fat and 
was not molting in the flight or body feathers. The stomach was empty ex¬ 
cept for what appeared to be the distal half of a crab claw and a small 
amount of a greenish fluid. 
Wedge-tailed Shearwater 
- ?- 
None of these shearwaters was seen by me nor do I remember any other 
members of the party mentioning that they saw any. It is not impossible 
that a few may have been present but were overlooked due to the brevity 
and cursory nature of the survey. 
Christmas Shearwater Estimated population---- 100 
I saw several of these shearwaters north of the coconut trees in the 
interior of the island and others were doubtless present. I saw no evi¬ 
dence of breeding activity.
