Abstract

Cestode fauna of wild birds in Bulgaria.

Abstract

Birds shot in mountain and coastal districts of Bulgaria were examined for cestodes. The 107 species found (including some recovered from birds that died in the Zoological Gardens in Sofia in 1955-1960) are listed with host(s), prevalence, intensity and locality. Numerous host and geographic records are listed and Raillietina sonini in Dendrocopus major, Monopylidium trigonocephalum in Pica pica, Sobolevitaenia moldavica in Turdus pilaris, S. similis in Prunella collaris and P. modularis, Vitta rustica in Muscicapa striata and Retinometra skrjabini in Anas querquedula were new host and geographic records. Most of the cestodes were Cyclophyllidea represented by 8 families. Hymenolepididae and Dilepididae were by far the dominant groups represented by 54 and 32 species respectively; the remaining families and Tetraphyllidea (Tetrabothriidae) were represented by one to 4 species. The study demonstrated that the fauna of high mountain birds in Bulgaria is rich and varied; it includes S. similis, a species that has never been so far recorded outside the Soviet Far East.
