Ludwig, JP 1964 22 Frigatebird was seen at Kilanea Lighthouse. I left Kauai at 1400 aboard an Aloah Aircraft arriving at Maui approximately 1600. Due to the lateness of the day I did not get a chance for further field work and spent the evening catching up on overdue Rest and Refueling. We stayed beyond Lahina at Napilee Beach at the Mauian Hotel - A ok. February 28, 1964 Maui, Kehei, Mud flats: About 1100-1245 accompanied by Dr. Fred Ludwig, I visited the Kehei Mud flats area. The flats were quite dried up compared to 4 weeks ago and the birds were mostly confined to the areas near the small river which feeds into the ocean here. There were definitely fewer stilts, but about the same numbers of Heron, Sanderling and Plovers. Increased numbers of Turnstones and Tattlers were noted. We photographed mostly today, but did note that the Stilts (seemed to be paired) were attached to a particular point of land. They seemed to already have staked out territory. However, only 3 stilts were seen all morning. The Herons represented all age-classes and I noted that each bird had its sacrosavent fishing territory which he defended against all comers. Age was not important so immatures defended successfully against adults as well as immatures. Approximately 50 percent of the birds are im- matures. Noted 2 Chuhais on the road to Kehei from Lahina. February 29, 1964 Maui, Kanaha Bird Sanctuary. This morning I visited the Sanctuary
