This image depicts an animal enclosure within the Sofia Zoo in Sofia, Bulgaria. The scene centers on a pond with greenish water, reflecting the bare trees of the background. In the midground, an artificial, low-lying island or concrete platform is situated within the pond. On this island, four white pelicans are present, all in a resting posture. Two pelicans are lying prone on the forward-left section of the island. One pelican is perched on a dark, bare tree branch lying horizontally on the left side of the island. A fourth pelican is seated on the right-rear portion of the island. A small, dark object, consistent with a turtle, is visible at the water's edge on the left side of the island, adjacent to the fallen branch. A slender, bare sapling with multiple upward-reaching branches stands upright on the right side of the island. The background features a dense forest of bare deciduous trees, indicative of late winter or early spring. Behind the pond's edge, a series of terraced concrete retaining walls ascend the bank, leading towards the treeline. A prominent, gray, rectangular concrete structure is situated centrally on the bank, behind the island. The lighting indicates bright daylight.
