have a dusky brown belly as immatures: Once they loose 
their down they are easily distinguished from Masked 
Chicks. 
Red-footed Boobys nest in the Scaveola tops. Adults 
have bright red feet and weigh 2 to three pounds. Chicks 
remain in the scaveola, and are greyish in color with 
greyish to greyish-red feet. 
Caught up on the banding schedules and collected 
another masked booby immature with a broken wing. It 
seems as though broken wings ( from collisions with 
the Loran Tower guy-wires ? ) are a major cause of 
juvenile mortality in this species. Of 13 non-flying 
chinks alive in area to the north of the LORAN tower 
three have had broken wings. Since they will eventually 
have died without contributing any offspring to their 
species, I have collected all three. All breads have 
occurred in the area of the wing from the distal end of 
the humerus to the middle of the radius and ulna indica¬ 
ting injuries during flight.

Surveyed and made maps of vegitation in the two 
shearwater study areas, and took a few pictures of the 
boobies nearby. Rain at 1000 and skinned booby in after¬ 
noon. Saw a dowitcher after dinner, but could not 
get close enough to collect it. 
IO- 3-63 
Heavhy rain all night and until 1200 today - seems 
as taough it will never stop. Skinned a booby this 
morning ( the third immature Masked with a broken 
wing ) and hunted in the afternoon, bagging a Short¬ 
billed Dowitcher in the process. There may also be 
a Phalarope here, but at 1900 when I saw him the light 
was too poor to be at all sure of this identification. 
In the evening we banded on the Shearwater plot 2, but 
found few birds above ground, although there were many 
moaning below ground. Apparently the bright light of 
the full moon and the wetness of the grass and ground 
O kept them in their borrows. Bill caught a lizard of 
a sort that I have never seen: This thing has an 
immense tail.
