But what
is most interesting in the valley is the presence during
the nesting season of some species from the southern
complex of passerines: Olive-tree, Olivaceous, Barred,
Subalpine, Orphean and Sardinian Warblers, Red-backed,
Woodchat and Masked Shrikes, Rock Nuthatch, Crag Martin,
Red-rumped Swallow, Cirl and Rock Buntings etc. It is
possible to see also the Great Spotted Cuckoo –
one of the most exciting and scanty Mediterranean bird
species, breeding in Bulgaria. |
