Between 1996 and 1999 diurnal raptors were counted using roadside surveys in the Richmond River district in
north-eastern New South Wales. A total of 3 101 raptors of 17 species as recorded. Relative abundance of raptors (all
species), expressed in terms of individual sp er 100 kilometres travelled, was 10.75 birds per 100 kilometres, which was
markedly higher than had been reported for the area previously. Two species, Nankeen Kestrel
Falco cenchroides and
Black-shouldered Kite
Elanus axillaris, were most frequently recorded, comprising 56 per cent and 24 per cent
respectively of all raptors counted. Both species demonstrated marked seasonality associated with autumn-winter
movements into the area. lssues relating to vehicle-based surveying of raptors are discussed.
