The sand martin, also known as the bank swallow or European sand martin (Riparia riparia), is a small migratory bird found throughout Europe, Asia, and Africa. Recognizable by its brown upperparts, white underparts, and distinct chest band, it nests in colonies along riverbanks, cliffs, or man-made structures. Sand martins excavate nesting burrows in sandy or loamy soil, providing protection for their eggs and chicks. As insectivores, they contribute to insect population control by catching flying insects like flies and mosquitoes mid-flight. Sand martins are appreciated for their ecological importance in maintaining insect balance.

The black stork (Ciconia nigra) is a notable wading bird known for its black plumage with white underparts, complemented by a red bill and legs. It thrives in diverse wetland environments, preying on a variety of aquatic creatures and insects. Black storks exhibit monogamous behavior, building sizable stick nests in tall trees close to water sources. They undertake migratory journeys, with European and Asian breeding populations migrating to Africa during winter. While categorized as Least Concern, conservation initiatives aim to mitigate challenges like habitat degradation and disturbance during nesting periods.
