A 16-ha site was studied on the Keauhou Ranch, Hawai'i, to<br />

determine the interrel<strong>at</strong>ionships between veget<strong>at</strong>ion type and<br />

presence <strong>of</strong> n<strong>at</strong>ive and exotic birds. The area was subdivided<br />

into 64 0.25-ha plots and the veget<strong>at</strong>ion sampled on each plot.<br />

On a twice-monthly basis, birds were system<strong>at</strong>ically mapped on the<br />

study site, and these d<strong>at</strong>a compared with the veget<strong>at</strong>ion samples.<br />

Birds were identified as to species, and when possible as to sex<br />

and age. One year <strong>of</strong> d<strong>at</strong>a has been collected and preliminary<br />

analysis shows inter-specific differences in habit<strong>at</strong> preference.<br />
