II. Petrel and shearwater breeding areas on Green Island, Kure ^toll 
A. Study areas 
1. Two 200 foot square study areas have been staked out in 
areas of noted concentration of petrel and shearwater 
burrowing activity. The areas are primarily of grass- 
vine association bordered by Scaevola and with S caevola 
clumps scattered throughout. 
2. The vegetation pattern of these areas has been carefully 
mapped. 
3. Several banding trips have been made through these areas, 
and more will be made in an attempt to band as large a 
segment of the population as possible. 
4. The position of each burrow within the study areas is 
being plotted, and the condition of use of each burrow 
determined. 
B. Banding returns 
1. The burrowing Procellar!ids are presently at an ebb in 
their breeding cycle on Kure. Project personnel will 
check these areas closely each month to continue banding, 
and, hopefully, to obtain returns on our own birds, 
especially when the next breeding cycle begins. 
C. Growth and development 
1. Data will be kept on the growth ana development of as 
many young birds as possible when the population begins 
breeding again. 
2 . This collection of data wall include weights and measure¬ 
ments, photographs, and known age specimens. 
D. Burrows 
1. Data will be collected on the microenvironment of the 
burrow, including temperature and relative humidity. 
2. Burrows will be dug out and mapped, and carefully checked 
for insect commensals or parasites.
