- 6 - This call given when males are pursuing females. Female flies to high bare limb and begins walking along a horizontal branch toward the protection of the foliage. The male flies up to her and gives this creaking note possibly just as he alights. He walks rapidly after her, following thru foliage, and by jumps to the other branches where the female goes. Then on to the next tree. Females very hard to find and to collect. Much less often seen in long flights. Collocalia inexpectata Saipan Present year around. Seasonal fluctuations noted to some degree. For instance in Jan and Feb, these swifts would gather in the area of AGF headquarters (open treeless area on the e slope Mt Tapochau) at dusk. Thousands of them all foraging low over the ground. This particular congregation not noted at that place other months. At a given season, both pairing and flocking can be found. One canyon had a pair that had a regular forage beat just like a pair of Rough-winged Swallows - generally at the level of the lower branches of the biggest trees. The round trip must have been about 75 yards, and they made it every minute or so. At the same time there was an entirely unrelated flock up above a nearby hilltop, which was milling around over the ridge. About 50 birds. No organized beats, no pairs. Very common on Saipan, but usually around canyons, steep hillsides, where plenty of large trees. Flight very slow for a swift, and faltering. Tinian Extremely rare. Seen only 3 times in 4 weeks, each time a single bird. Guam Nesting found in caves on cliffs by Dave Johnson. Lots of guano. Nest said to contain a lot of plant material and is there for inedible. Not-as-frequently- Occurence same as Saipan, altho they get into a lot larger flocks. Bigger island, more swifts, and much bigger flocks - up to thousands. -- Note very interesting stomach analyses in catalog -- Halcyon cinnamomina Guam This bird is so different in habits, calls, habitat, nesting, etc from chloris as to leave no doubt in my mind that they are different species. It is shy and retiring, is never seen on conspicuous perches in open country, never seen on phone wires, and is hardly ever heard to make a sound. It was a long time on 26 May before I found out what these uncanny weird sounds were. Finally tracked it down (through some of the densest jungle and undergrowth I have ever seen) to a large banyan type of tree where there was a nest hole about 20 ft up belonging to a pair of these kingfishers. Young were being fed and giving food calls but the strange ventriloquial wheezes and rolling calls (of unique timbre) were coming from the parents. Later on Guam, I finally heard a note suggestive of chloris, but greatly toned down, and somewhat mellow - a series of two syllable calls, the 2nd component of which very much higher than first [illegible] a parallel to a donkey's"hee-hoh". Always in pairs, or pairs with a few young around - in latter
