Description
Harris' hawk (Parabuteo unicinctus) is distributed from the southwestern United States to southern Patagonia (Brown and Amadon, 1968; Couve and Vidal, 2003), inhabiting mainly vegetated open lands such as semi-arid deserts, shrublands, savannahs, open woodlands, and prairies, as well as agricultural areas with trees (Bednarz, 1995; Ferguson-Lees and Christie, 2001). According to studies conducted in North and South America, this hawk preys on a wide spectrum of prey including lagomorphs, small mammals, birds, reptiles, and insects (Jaksic et al., 1980; Whaley, 1986; Bednarz and Ligon, 1988; Jimenez and Jaksic, 1993; Bednarz, 1995). However, information on prey of Harris' hawks in South America is scarce with reports only from Argentina (Aguilar and Kowalinski, 1996), Brazil (Silva e Silva and Olmos, 1997), and Chile (Jaksic et al., 1980; Jimenez and Jaksic, 1993; Figueroa and Gonzalez-Acuna, 2006). Although diet of Harris' hawks is relatively well known for areas adjacent to the Andes Mountains (pre-Andean areas) of central Chile (Jaksic, 1997), no information is available from other geographic areas with potentially different prey. Here, we describe prey of Harris' hawks in a coastal area of central Chile. Our study was conducted in Reserva Oasis la Campana (2,500 ha), Valparaso region, central Chile. This reserve is adjacent to La Campana National Park (31[degrees]55'S, 71[degrees]08'W) in the coastal mountain range. The study site had uneven topography (elevation 300-1,800 m, slopes to 40[degrees]) and vegetation comprised of sclerophyllous forests and shrublands (Gajardo, 1994). Forests were composed mainly of Cryptocarya alba, Peumus boldus, Lithraea caustica, Schinus latifolius, and Quillaja saponaria that mostly covered ravines and lowest sites on south-facing slopes. Shrublands were composed mainly of Trevoa trinervis, Colliguaya odorifera, and Puya berteroniana, and extensively covered flatlands and hills. Climate is Mediterranean-arid (di Castri and Hajek, 1976) with mean annual rainfall and temperature of 109 mm and 20[degrees]C, respectively (Saiz et al., 1989; Pliscoff, 2002).
