Sounds and Vocal Behavior

The song of Blue Seedeater is described as "a pleasant warble, often ending in a little splutter, similar in quality to that of Slate-throated Redstart [Myioborus miniatus], ch'swee ch'swee ch'switto ch'seeu ptr-r-r, or a simpler, somewhat plaintive chi chi wee chee chee" (Stiles and Skutch 1989); as "variable, a high, slightly tinny to sweet warble suggesting [the song of] Passerina buntings, see see-wee-see si-si-wee or seet see-wee-see si-si-wee-su" (Howell and Webb 1995); and as "a brief, fast, somewhat jumbled warbling with a sweet quality, e.g., sweet-sweet-sweet-saweet" (Ridgely and Greenfield 2001b).
