摘要
The Wedge-tailed Eagle Aquila audax preys upon a diverse range of species and employs an impressive repertoire of hunting behaviours in a variety of habitats (Marchant & Higgins 1993). The few published accounts of Wedge-tailed Eagles hunting in or at least pursuing prey into dense forests are difficult to interpret and none seem to be of rainforest hunting as described in this paper. Fawkner (1991) described a chase through 'quite dense forest' in the Marlborough area and Mooney's (1988) account of a Wedge-tailed Eagle chasing a currawong through the canopy alluded to a closed forest habitat. Gaffney & Mooney (1992) state that in Tasmania, Wedge-tailed Eagles prefer to hunt in forest. Wedge-tailed Eagles have also been reported flying over closed forest habitats in Bega and in south-eastern Queensland (Smith 1984; Czechura 1985) and are frequently seen soaring over rainforest in north Queensland. Wedge-tailed Eagles are known to nest in closed forest habitats. This behaviour is particularly common in Tasmania (Gaffney & Mooney 1992), and a nest-site in an emergent Turpentine tree Syncarpia glomulifera was pointed out to SB by forestry workers on the Mt. Windsor Tableland. Below we describe some observations of successful foraging in tropical rainforest of north Queensland by Wedge-tailed Eagles and four hitherto unrecorded prey species.
