- 11 - peewee. On a horiztwig, made of cobwebs, a very dainty and smoothly constructed thing. Sides vertical. These birds sing in a regular morning chorus at dawn, they are about the only birds that do this. The song is delightful, and is startlingly similar to that of the Long Billed Ant Wren of Central America. It is a descending cascade of thin whistled notes, each very distinct in spite of the rapidity of the notes - so they do not constitute a trill. Pitch is very high, but not quite as high as song of the GC Kinglet. Song often preceded by longer high call notes, which can also be used separately as call notes. Easily attracted by imitation of its song. Next to Zosterops, this is the most abundant bird on Saipan and Tinian. On Guam, it is the next most abundant to the Starling. (Ie on Guam, the Starling is exceedingly numerous, and Zosterops is relatively rare. Monarcha takatsukasae Tinian In about equal numbers with Rhipidura with-the- and in same type of habitat, with the addition that this is exceedingly abundant in tall cane and other dense growth in marshes. Two such spots are the forest around Lake Hagoi, and the tall cane marsh at Marpo Valley. In such strictly cane and marsh habitat, Rhipidura is absent. Monarcha is a more stolid, phlegmatic bird than Rhipidura, it ambles around in the foliage like a vireo, with the same occasional dashes after flying insects of hovering before a twig that vireos do. It is more often found on an exposed perch in the understory of the forest, sitting upright like a flycatcher and making insect-flights. Calls are loud harsh wren-like notes. Given often when birds are chasing each other. Song is beautiful , clear, and flutelike, a very pure tone. Usual form is three syllab lst 2 short grace notes , 3rd a beautiful"wheeeooo" of descending inflection. Dybas found a nest of this species in March. Like Rhipidura-the-birds-are-independent,-foraging-alone, but because of their great numbers, they are always coming into association with each other. Song especially heard in evening. Generally paired. Myiagra oceanica Guam Song consists also of a series of clear sweet whistles, this time a series of 7 notes, slightly inflected, all on the same pitch. Sounds exactly like one of the songs of the Plain Titmouse. A common species on Guam, tho not as numerous as the Fan-tail. Is more of a typical flycatcher in habits, foraging out from an exposed perch in the understory of the jungle. Call is a singel whistled tone. Found in larger trees, and higher up that Rhipidura. Also a rasping wren-like call. Come readily to imitated calls or squeeking. Almost always found inpairs . Absent from open forest on dry rocky gnd. In such a place, they will be found in the occasional dark-green trees with small leaves (resembling Canyon Live Oak). Otherwise, always in the lower tree levels of the densest and highest forests. Flycatching posture is upright.
