23 Feb. (cont.) in the area. This is a drop of about 
500 from our calculation earlier. Perhaps reflected 
in the figures is the highs: number of oirds that had 
been handled yesterday, birds xa that may still have 
been hanging around the area. 
After dinner I checked the NAF and SAF for the same ; 
thing, and found 71 of 232 birds counted painted. Shis 
is 31 per cent of those birds present. We have painted 
to date 817 birds in the area; sa calculation thus 
provides us with a figure of at least 2700 birds using 
the area. If these figures are anywhere near accurate, 
there may be 5,000 birds using the two areas, plus 
those S. of the runway and those ringing the north beach. 
I saw old Laysan inthe same part of the NAF today - 
the location he has always been in when seen. This 
is the bird with the checkerboard neck, caught originally 
in Dec. with an old worn band. 
Bob and Alan chased down more Laysans in SAF and NAF 
this evening, and banded an additional 61 birds. 
Rat trapping will continue tomorrow. I hope that 
I don't get bitten again. 
We saw three Fairy Terns flying over the NAF during 
the trapping. One injured Fairy Tern was found, its 
wing ripped off. It could not be bled. 
24 Feb. Rat trapping all Am., finished by 1135* We only 
caught 98 rats, and of these 17 were new, we are now 
up to 0143 on the new rats. There were very few in the 
A-B- area, more as we progressed East. The cloud cover 
we have been having finally brbka,and the last hour was 
in clear, warm weather for a change. 
After lunch we split up. Bob banding inthe Centraj.
