dc.description.abstractBETWEEN SEPTEMBER AND DECEMBER 1989 WE ANALYZED THE EFFECT OF FLOCK SIZE ON FEEDING AND VIGILANCE BEHAVIORS OF THE BLACK-FACED IBIS (THERISTICUS MELANOPIS). THE BLACK FACED IBIS FORMED SMALL SIZED FLOCKS DURING THE STUDY PERIOD. FLOCKS OF 5 TO 6 INDIVIDUALS REPRESENTED THE HIGHER PROPORTION OF ALL OBSERVATIONS. OUR RESULTS SHOW THAT FEEDING AND VIGILANCE VARIABLES WERE INDEPENDENT OF FLOCK SIZE. ONLY PECKING AND VIGILANCE RATE SHOWED POSITIVE SIGNIFICANT CORRELATIONS WITH FLOCK SIZE. HOWEVER, THE EXPLAINED VARIANCE OF THE FLOCK SIZE FOR ALL VARIABLES ANALYZED WAS MINIMAL. WE CONCLUDED THAT THE BLACK-FACED IBIS HAS PROBABLY DEVELOPED EFFICIENT VIGILANCE SYSTEMS WHICH PROVIDE SMALL FLOCKS A GREATER PROTECTION AGAINST PREDATORS AND EVENTUALLY GREATER TROPHIC BENEFITS.
