Figure 2: Egyptian Goose (Alopochen aegyptiaca) goslings in the mixed Crowned Eagle (Stephanoaetus coronatus) nest. The youngest gosling (left) has just completed hatching and remains damp, while the older gosling (right) had been first observed piping on 29 August at 16:27 and completed hatching overnight. Both goslings were subsequently brooded by the adult eagle alongside the unhatched eagle egg. Photo credit: Brendan Smith.

Figure 3: One Egyptian Goose (Alopochen aegyptiaca) gosling climbs onto the back of the adult Crowned Eagle (Stephanoaetus coronatus). Earlier that morning (07:55) the first gosling moved to the edge of the nest and jumped from the 30 m-high platform. In the following days, the eagle’s behavior shifted from tolerance to predation toward the remaining gosling. Photo credit: Brendan Smith.
