Cropped version of the photo I tagged as habitat. Note the white head and throat and the white patch on the belly, that distinguish this plumage from adult female.
観察結果の詳細
A single female flew southward over Laguna Sur and then disappeared behind the hills. Jesús was the one that first spotted it, while the other group members were focussing on the birds in the lake. A large bird with a long thin tail, split into two streamers, and long wings and a long thin bill. It had a black belly that was well demarcated from its white breast. This species can only be confused with other frigatebirds, but Magnificent Frigatebird is the only one expected in Peru. Edit 3-Mar-2023: Further analysis of the photos reveals that this is not an adult female, but a juvenile of unknown sex. Its face is completely white and it also shows white on the belly. The black belly mentioned originally is in fact an incomplete black beast band, which coincides with the juvenile plumage as depicted in Birds of Peru (Schulenberg et al.).
