The Great Non-Tufted CMMDR (domestic). Found nesting in crevices of slimily arranged Yellow post-its (2x3) and cramped piles of anything.
Call is single-noted shrill 'job-job-eneee-thing-job' or, when mating, a four syllable shriek "sahr--eee sah-ree".
Elders have lame foot, knee, arm and indigestion causing it to bloat.
(Natural enemy is Common EN-Sign (Judaic Family) with hairy grey bill. Solitary Bird with No Friends.)
