This research was carried out during May-September, 2003. Zarrinkola and Marzoonabad are the important ab-bandans basis of area and species diversity in Mazandaran province. In both Ab-bandans, seven breeder bird species were observed: three resident species and four summer migratory species. Whiskered Tern (Chlidonias hybridus), Great Reed Warbler (Acrocephalus arundinaceus) and Little Grebe (Tachybaptus ruficollis) were breed in both Ab-bandans. Common Moorhen (Gallinula chloropus), Little Bittern (Ixobrychus minitus) and Penduline Tit (Remiz pendulinus) only breed in Zarrinkola Ab-bandan, whereas, Coot (Fulica atra) only breed in Marzoonabad Ab-bandan. Whiskered Tern (C hybridus) was the dominant breeder species in both Ab-bandans. It depended to Nymphaea Alba, whereas, Great Reed Warbler (A. arundinaceus) has high depended to dead Phragmites. Common Moorhen (G. chloropus) and Little Bittern (I minitus) were preferred Phragmites vegetations. Little Grebe (T ruficollis) and Coot (F. atra) was breed in regions with low and medium vegetation. Salix sp. was selected by Penduline Tit (R. pendulinus) among the marginal regions of Marzoonabad Ab-bandan. Natural and human threats have effects on the breeding habitats in two Ab-bandans. But, human effects have more intensity in Zarrinkola Ab-bandan.
