Bearing in mind the diversity of the relief, type of bedrock, different microclimates and other circumstances, it is possible to distinguish many habitats arranged in a mosaic layout with various bird communities, which were zoned primarily with regard to plant communities. To date, as many as 167 bird species have been registered in Učka Nature Park and its contact area. In addition to various types of forest habitats, particularly important for birds are rocky habitats, because many birds of prey nest in such areas. Some of these birds are endangered, such as the golden eagle (Aquila chrysaetos) and the peregrine falcon (Falco peregrinus).

Although it used to nest here, the Eurasian griffon vulture (Gyps fulvus) today only flies over the areas of Učka and Ćićarija in search of carcasses. Among other protected bird species, particularly interesting are those living in grassland habitats, such as the ortolan (Emberiza hortulana) and the woodlark (Lullula arborea). For their protection it is necessary to preserve such types of habitats.
