Ludwig, J. P. 1964 17 enough to hold head erect and call weakly]: both were on the point of the colony and may represent precocious breeding of 2 birds as these nests were located within 10 feet of each other. We also estimated 500+- 50 Adults on the roost, and 15+-5 immatures; still noted only 3 dark-phase, but there may have been more unseen in the poor light. After our banding, the birds seemed to be settling readily back on their nests, although some fighting and confusion was apparent. On the way in to Hanalei from Kilauea we saw 2 Barn owls along the road. One bird was watched for about a minute as it flew from fence post to post along the road. All 3 owls were noted in a 5 mile stretch of highway, suggesting a high density of owls in this district. February 27, 1964 Up at 7 to return to the Booby colony. We stopped on the way at the Taro Patches near the Hanalei River there seeing the following birds: black-necked stilt, black-crowned Night Heron, Golden Plover, Wandering Tattler, American Coot, Ballimule, Shoveller Duck. After 40 minutes we moved on to the Booby Colony where we counted the following numbers of nests and eggs. Nests with Eggs - 50 Nests with Chicks - 3 Nests without Eggs or Chicks - 71 Inaccessible Nests - 67 TOTAL-191 Nests Probably some 200 nests will be made and used here before the end of the season. We also found many wedge-tailed Shearwaters (+Bulwer's Petrel?)burrows along this ridge.
