R.Clapp - 1964 Nov. 12 - Jaluit Atoll and At Sea Got up early in the morning and went over to Enybor with Binion, Ken, and Dave. The same flock of 15 Black-naped Terns was sitting on the smae sand spit as it was the other day. Intermixed with these birds and roosting with them were about 30 Common Noddies. Binion did the shooting, while I took care of the specimens. 3 sumatrana , one adult and two immature, were obtained as well as a Common Noddy and a Hawaiian Noddy. The immature Black-naped Terns were both in primary molt. Those feathers in the wing which had been already molted and regrown were much lighter in color than those immature feathers which they were replacing. The anterior portion and the anterior half of the posterior portion of the web were but a very faint, smoky gray which would appear in the field as white. The older, outer primaries, on the other hand were very dark gray to black in this area. Perhaps it might be possible to estimate age of young Black-naped Terns in the field by the amount of black showing in the wing in flight. These immature birds also varied from the adult plumage in that the feathers on the anterior, proximal part of the wing had a dark bar on them. In addition, I thought that there was a variation in gape color between young and old birds, with the younger birds having a distinctly more pinkish gape, while that of the adult tended to be salmon colored. However, the colors were too similar and the sample size too small for me to be sure of this. We went then to the island, off which the ship is anchored and where the missionary, Father Donohue, holds court. We were feted by yet another women's club. This group wore a uniform consisting of a dress with a pattern of red and white squares. Leis, of course, were the order of the day and they gave us a number of woven items including mats, cigarette cases , and some purely decorative items. When we returned to the ship Larry and I spent the rest of the day skinning while the others kept a largely profitless watch. Stopped skinning at six, watched Mary, Mary, and skinned until 2300.
