then throughout the day.  The temporal distribution of these patterns is very reminiscent of the ”Rattle - Flourish Day Songs” of Brown-capped Bush-tanagers [[underline]] (Chlorospingus opthalmicus) [[/underline]].
     
     Some of the probable relationships between the individual components of Streaked Saltator Day Songs and vocalizations of other finches and tanagers will be discussed in more detail below, after the corresponding patterns of other Saltators have been described.  

      The Day Songs of Streaked Saltators in central Panama are quite stereotyped in form.  Only two variations are common.  Sometimes the terminal Rattle is omitted.  Sometimes an extra, fourth, introductory “Duh” Note is inserted before the Whistle.

     There may be considerable differences between the Songs of Streaked Saltators in different regions.  All the Song phrases of one individual studied near Cerro Punta on the Volcan de Chiriqui in western Panama were composed of introductory notes like those of the birds in central Panama, followed by one long Whistle, followed by one short Whistle, followed by another “Duh” Note.  The Whistles themselves had a faint rattling undertone, but there were no pure Rattles.  The only pattern of Costa Rican Steaked Saltators described by Skutch which might be closely related to part of the Songs of the Panama birds is “a refrain of four or five whistled syllables, forming an exquisitely modulated crescendo, and with the last syllable the longest”.

     All Panamanian Streaked Saltators utter their Day Songs from largely or completely unritualized erect sitting postures (see figures 1a and 1b).  

      The major ^[[handwritten]] TYPES OF [[/handwritten]] vocal patterns (or groups of patterns) of Panamanian Streaked Saltators are quite “discrete”.  They do not intergrade with one another to any appreciable request.  In this respect, Streaked Saltators resemble most other finches and tanagers and are very different from Yellow-rumped Tanagers.

     Three copulation attempts by Streaked Saltators were observed in central Panama.  Two of these began when the male flew straight on to the back of the
