Graciela Jerez — Merlo, Province of San Luis

Official source account — 2020 annual report, printed page 94: Graciela Jerez described the photographed objects as drone-like but without legs. CIAE compared the two objects' colours and apparent anatomy, concluding that they were probably birds of the same species approaching the camera together. It suggested house sparrows or a similar species without treating that identification as certain. The agency classified the supported conventional explanation Type B. The summaries distinguish reported observations from the agency’s proposed explanations. Source Type A/B ratings describe explanatory confidence and are not encounter classes. The map uses an approximate GeoNames locality centroid, not the observation point.
