(69) The body was smaller and the formation of the bill around the nostrils different.Maybe a young plumage,but what about the iris?They feed in medium-sized trees that bear bunches of very small green berries,something like an elder.One of the natives discovered a nest afew feet off the trail at about 4500 feet.It was quite simple- a small flat pile of twigs and a little moss laid on a small,bare branch eight feet off the ground. Two eggs were present,well incubated.Unfortunately they were broken in the portage down to the camp. The smaller birds that inhabit the higher land are as follows: warbler,ashy fantail,thickhead,large white-eye,green parrakeet,curve-bill, small cuckoo,red-bellied flycatcher,small swift,midget,and black honeysucker.Of these the last five span the range of altitude in the area we are working from sea-level to 5500 feet.Of the little warbler not much can be said except that it possesses a true warble- high and clear;the song of the white-eye is longer but lacks the liquid quality.They are often seen in pairs and are primarily seed-eaters.On the whole it is much like the white-eye in its visible habits.The two are sometimes together- a dozen feeding in the matted liana leaves that blanket the trunks of the larger trees.However,they are not as common as either the white-eye or fantail. These three species hang together as a general rule;when you see one you will probably see another.In larger groups they attract attention by incessant calling and lively activity.The large white-eye and the curve-bill can be found most readily in the terrain from 2500-5500 feet.We have observed the latter taking nectar from blossoms;but several stomachs have revealed seeds and insects.They seem to be attracted to the thick,lower bush in the high elevations.When they have been suddenly disturbed I have mistaken them for thrushes on several occasions.The small cuckoo is one of the few birds that ranges at all elevations.Bougainville is the first island that has yielded such a large series.Its three note call of descending sharps is heard everywhere,particularly toward evening.The small, green parrakeet fans the air in the high treetops above 3000 feet,flying about in flocks and swift as arrows.They feed up there with much squeaking,mostly seeds and bark insects;we have also found the little berries (so favored by the long-tailed dove)in their crops.Of the rest-red-bellied flycatcher,small swift,midget,and black honeysucker I have nothing new to offer. Bougainville hawks present an interesting array of six species- black hawk,white-breasted hawk,striped hawk,blue-beaked,white-headed(fish)hawk,and the eagle-hawk.The last has been seen several times but has not been taken.The range of the hawk is so protracted due to its great cruising power that one cannot put any species in a category of altitude.Still,the black hawk is the only kind taken above 3500.And the white-breasted hawk.The others were collected below 3000.The eagle-hawk I have seen sailing around up about 4000 feet and it surely has the strength to fly over the mountains with ease.But it seems to favor the coast and is believed to nest on lonely,rocky islets a short way out to sea.I once saw one flying along the shore with a stout branch in its talons.G.R., got the only specimen of the beautiful black hawk somewhere around 5000 feet on a rainy afternoon.In its stomach we found the remains of a small bird,evidently a white-eye,also what looked like much-decomposed lizards and large insects.I was lucky enough to shoot the white-breasted one.It is a close counterpart of the one taken by me on Tulagi I.,when G.R.,and I first arrived.Mr.Beck took another on Tauno I.,off Fauro.They were smaller but like the Bougainville bird in every other detail- iris,straw-feet,yellow-beak,blackish grey,lightening toward the tip.Both of these
