Head-tucked walk itself functions in hiding the bill. 
Rd-w features a swinging of the head from side to 
side through an arc the center of which is directed at 
the antagonist. However, just prior to attack the bill, 
I think, is directed at the antagonist. Could it be 
that Hd-w . represents a compromise in the aggressive 
and appeasment moods of the displaying bird e as the 
direction at the opponent is aggressive, while the 
swinging away is appeasing. To be looked for in further 
work. 
8 Fefe. A word about the overall pattern of Laysan 
returns and banding should be mentioned. All banded ana 
returns are being painted - all those found on chicks 
are given a horizontal line across the upper breast - al] 
those ix that are walkers are given a spot on the 
breast. The color schema for the island is as follows; 
Blue - to be used on birds on NE and NW beach only. 
Green - birds of central roost and its extensions — SW 
beach, north side of runwa y, and 3A2. 
Orange - birds of N roQst, NAF, and SAF. 
Copper Kettle - birds S. of runway, inc. SE beach. 
This AM went out and got returns on all birds we 
could find S. of runway - Copper Kettle territory. We 
marked 165 birds. This brings the total so far this 
period to 643 Laysan returns, 201 banded. Dennis and 
Bob have accounted for most of this. 
I managed to crank out another batch of recovery 
forms - we are getting about 10-15 Laysans found 
dead every week. The rats are busy. I found another 
young laysan killed by the rats. ‘ The young that I moved 
from nest 33 to nest 29 is thriving this PM. The 
young was fat and well fed - like a rubber balloon 
filled with oil. Rereading Feb. 7 notes I see I did not 
inciudethis info. On Feb **7 nest 33 was abandondoned by 
the male who had been on the nest since January 9, 1965* 
The female had not been to the nest in that time, and 
by Feb. 7 the male was uneasy. He left the chick, then 
II days old, and it was already thin when I found it in 
the nest looking all about. The chikc was attendee at 
1800 the 6th, so was p robably not abandoned until the
