Ariel Ahumada — Province of Santa Fé

Official source account — 2021 annual report, printed page 10: Ariel Ahumada noticed an elongated form only when reviewing a landscape photograph. CIAE interpreted its unequal ends and wing-related motion pattern as the blurred passage of a bird. The camera had frozen that movement without a contemporaneous visual sighting. The agency classified this as a supported Type B conventional explanation, acknowledging that the brief event could not be recreated. The summaries distinguish reported observations from the agency’s proposed explanations. Source Type A/B ratings describe explanatory confidence and are not encounter classes.
