Rodrigo Astobiza photograph

Official source account — 2019 annual report, printed page 26: Rodrigo Astobiza found two apparent objects after reviewing a photograph taken on National Route 40 in La Rioja on 28 February 2019. CIAE compared their body and wing-like shapes with biological examples. It proposed two birds crossing the camera view and classified the account as Type B. The agency acknowledged that the brief passage could not be reproduced and cited the absence of a prior visual observation as supporting context. The summaries distinguish reported observations from the agency’s proposed explanations. Source Type A/B ratings describe explanatory confidence and are not encounter classes.
