pairs or ^[[handwritten]] (IN THE BREEDING SEASON) IN [[/handwriting]] small family groups of parents with one brood of (one or two) )[[/strikethrough]] young. [[strikethrough]] in the breeding season. In the non-breeding season, individuals are usually alone. [[/strikethrough]] They usually do not associate with mixed flocks or individuals of other species during either the breeding or non-breeding seasons.

     The account in Skutch (1954) would suggest that the general social habits and habitat preferences of Streaked Saltators in Costa Rica and Colombia are much the same as in Panama.

     There is nothing very distinctive about the locomotory movements or intention movements of Streaked Saltators or any other species of the genus with which I am familiar.  They all perform ritualized Wing-flicking and Tail-flicking movements which are not significantly different, in form, from those of [[underline]] Ramphocelus [[/underline]] species or the Green-backed Sparrow [[underlined]](Arremonops conirostris) [[/underline]].  As in the latter species, Tail-flicking is often accompanied by fanning of the tail feathers.

      The unritualized and slightly ritualized hostile movements and postures of Streaked Saltators seem to be equally undistinguished in form, but comparatively very rare, under natural conditions.  Single individuals and mated pairs [[strikethrough]] of this species [[/strikethrough]] apparently maintain territories or exclusive home ranges.  The same individuals are found in the same areas for (at least) months on end.  But I never saw an actual fight, or even close  contact, between presumably territorial neighbors in the wild.  The most vigorous hostile reactions observed were performed by a captive individual during disputes with a Buff-throated Saltator.  Its hostility took the form of Gaping (sometimes silent, sometimes accompanied by Hoarse Notes --- see below) and “head forward threat” postures (sometimes with Gaping, more often without).

     Most of the displays of Streaked Saltators are vocal.  Among them are “Tsit” Notes, a variety of Hoarse Notes, Day Songs (including “Duh” Notes, Whistles, and Rattles), and Dawn Calling.

     “Tsit” Notes are sharp, thin, and not very loud.  They may be uttered singly or in irregular series.  They are uttered in a variety of circumstances, when
