4 Numenius tahitiensis Guam 6 June 45: One shot as flew over slough at river mouth and lit on pole. Possibly one more seen that day out compared to total of about a dozen N. phaeopus. Heteroscelus Saipan Tinian Guam Seen from 7 Jan at least until 6 June 45 (Guam) always and exclusively on rocks at edge ocean. Saipan 26 Sept 45 2 fishing on h. Susupe . 1 coll - 4 gambusia Sterna albifrons Saipan 16 November 1945: Seen in channel foraging over open sea between Saipan and Tinian. Not certain but probably this sp seen on various trips over to Tinian. Sterna albifrons Anous stolidus Saipan Flocks seen in channel betw Saipan and Tinian on various ferry boat rides in Mch and Apr. Nesting or at least resting and flying to and from nitches in cliffs al along east side island. That is cliffs actually at the ocean's edge. Guam 31 May. One shot over jungle as chased a second, probably on some sort of mating flight which took them over the jungle. Gygis alba Saipan, Tinian, Guam Common, in fact on e of the most frequently seen and conspicuous birds around patches of timber on the two islands, Saipan and Tinian. Only one or two seen on Guam. Very rare there, or else just spread out more over the much larger island. On Saipan, one sitting all day long for a couple of weeks during February (I think) on high dea bare horiz branch of Breadfruit Tree near our lab. Found principally around large banyan trees especially on steep hillsides or overlooking gullies. Noisy at times - snarling and squawking. Hover a great deal over foliage and branches before alighting. Spend a lot of time flying ar und the trees and back and forth past the hillsides and cliffs where their chosen trees are located. Seems like an awful lot of useless activity - which is neither feeding nor mating(?). Timespent on the life history might show significance to this behavior. Typical courtship flight is pair zooming (close together) like swifts with wings held in crescent with 4" fish held crossinge in bill. 26 Sep 45 Saipan Ptilinopus roseicapilla Saipan Tinian Guam Found almost exclusively in the largest and densest and greenest braodleaved trees on all three islands. These trees incidently are must be in areas of extensive forest. Therefore, since Guam is proportionately more heavily forested, there are relatively many more doves there per acre. But they are quite common in suitable isolated patches of timber on Saipan, and to a lesser extent on Tinian. The/ only exception to finding them in that type of growth is at Saipan, Lake Susupe, where I found a couple in the Casuarina trees at the edge of the lake, a mile from any native forest. They are absolutely impossible to see in the trees, because they stay so hich and sit so still, except when actually eating a berry or walking about the twigs
