RELATIVE ABUNDANCE OF NINE BIRD SPECIES OF THE ORDERPASSERIFORMES IN AGRICULTURE LAND OF ZLATIATA NATURA2000 SITEN.T. Kambourova, T.M. Michev, V. Katrandjiev, B. MichevCentral Laboratory of General Ecology, Bulgarian Academy of Sciences,2 Gagarin Street, 1113 Sofia; E-mail: larus@abv.bg, tanyo@abv.bgIn Zlatiata Natura 2000 site, a study was carried out on the relative abundance ofnine of the most abundant bird species which breed in different agricultural fields(Miliaria calandra, Emberiza melanocephala, Emberiza hortulana, Lanius minor,Lanius collurio, Sylvia communis, Motacilla flava, Alauda arvensis andCalandrella brachydactyla). The study was performed on the part of protectedzone Zlatiata in the framework of UTM squares GP03 and GP04. The transectmethod was used for determine the species composition of breeding passerine birdsand their relative abundance. We studied 35 transects, each 200 m wide and withdifferent lengths. Transects included the most widespread types of crops in theregion. The transects were visited two times during the nesting period (19-23.05.2008 and 10-13.06.2008). They were situated in the western part of theterritory of protected area Zlatiata Natura 2000 site (BG0002009). In wheat andbarley, the most frequently breeding species were the Skylark (Alauda arvensis)and Black-headed Bunting (Emberiza melanocephala); the former species occurredin all transects of this group. The Skylark is the most numerous bird species in alltypes of crops and has the highest relative abundance, 35.89 pairs/km 2 (mean for alltransects). The Skylark, Black-headed Bunting and Yellow Wagtail (Motacillaflava) were the most frequently breeding species in transects of sunflower. Intransects of maize, the most frequently breeding species were the Skylark andShort-toed Lark (Calandrella brachydactyla). The average height of Skylarksmating flight in the region is 41 cm.39ЗЕМНОВОДНИТЕ В ПОРЕЧИЕТО НА ДУНАВ (БЪЛГАРИЯ) -РАЗПРОСТРАНЕНИЕ И ОПАЗВАНЕБ. Наумов 1 , Н. Цанков 2 , А. Стоянов 2 , Г.
