circus aeruginosus การใช้

Until recently two species were generally recognized : the marsh harrier ( " Circus aeruginosus " ) and the African marsh harrier ( " C . ranivorus " ).
The "'western marsh harrier "'( " Circus aeruginosus " ) is a large harrier, a bird of prey from temperate and subtropical western Eurasia and adjacent Africa.
Small hillocks ( though showing degraded condition ) in the lake show big trees; birds of prey such as " Milvus migrans lineatus " and " Circus aeruginosus " have been recorded on these trees.
Predators of darters are mainly large carnivorous birds, including passerines like the Australian raven ( " Corvus coronoides " ) and house crow ( " Corvus splendens " ), and birds of prey such as marsh harriers ( " Circus aeruginosus " complex ) or Pallas's fish eagle ( " Haliaeetus leucoryphus " ).
