The Black Noddies were decidedly more numerous in the higher Scaevola on 
other areas® About 50 of these noddies roosted in each of the three 
clumps of Casuarina . One of the birds handled was a partial albino 
(712-5008 o). Both of the innermost right tertials were white or partially 
white. The innermost tertial was pure white with a white vane while the 
feather next to it was mostly white with an elliptical dull grey-brown 
center»

Seventeen Black Noddies were examined to determine stage of molt in 
the primaries® Two (12$) had fresh primaries, one ( 6 $) had not yet begun 
1 to molt, and the rest ( 76 $) had some primaries in active molt. Twelve of 
the 13 molting birds showed a normal proximal-distal molt progression but 
| one, (923*19192 - a bird banded as an adult on Whale-Skate* French Frigate 
Shoals in August 1 966 ) had a discontinuity in the left wing and an 
apparently normal molt" in the right wing. 
The PMS scores obtained for the Lisianski Black Noddies clearly 
indicated that they had finished their nesting cycles some time before 
the birds on Laysan. The range of PMS scores and mean score for 13 birds 
in active molt on Lisianski was 20-94 and 57 whereas the range of scores 
and mean score for 9 in active molt on Laysan was 42-86 and 75® When all 
birds examined for molt on the two islands are included in the total 
(including birds that had finished or not yet begun molt) the resulting 
mean PM scores are 59 for Lisianski (n:l 6 ) and 86 for Laysan (n:l 6 ). 
On 4 September a Johnston streamered Black Noddy was 
captured as it roosted solitarily about two feet up in Scaevola, at the 
south end of the island. Two other returns were also interisland move¬ 
ments. One had been banded on Pearl and Hermes, the other on French 
Frigate Shoals. • *
