Hippolais olivetorum

Hippolais olivetorum, commonly known as the Olive-tree Warbler, is a large warbler species that migrates between Europe and Africa.

In Croatia, this bird is typically found in olive groves, dense scrublands, and other areas with Mediterranean vegetation during the breeding season. With its subtle gray-brown plumage, the Olive-tree Warbler may not be as visually striking as other species, but its strong, repetitive song makes it stand out.

As a ground-nester, it relies on dense vegetation for protection, highlighting the importance of preserving Croatia's Mediterranean ecosystems to support this species and others like it.
