此物種詳細資訊 Trinidad and Tobago 狀態: 原生 入侵: 出現紀錄: ????? 來源: Friedmann, 1929 此地點的物種說明: Shiny cowbird Molothrus bonariensis subspecies minimus is known to be present on these islands. 影響: 寄生: Molothrus bonariensis parasitises three main species in Trinidad and Tobago: the house wren (Troglodytes aedon), the red-breasted blackbird (Leistes militaris) and the yellow-hooded blackbird (Agelaius icterocephalus). There are also records of parasitism of the tropical kingbird (Tyrannus melancholicus). M. bonariensis does not appear to affect the reproductive success of any of these species (Cruz et al., 1995). 最後修改 : 3/07/2005 3:45:02 p.m.
