THE FOOD STORAGE BEHAVIOUR OF THE NORTHWESTERN CROW by PAUL C. JAMES1)2) and NICOLAAS A. M. VERBEEK (Dept. of Biological Sciences, Simon Fraser University, Burnaby, B.C., Canada) (With 2 Figures) (Acc. 25-II-1983) Introduction ' Much attention has been focused on avian food storage behaviour, in terms of the various strategies shown by different species (BALDA & BATEMAN, 1971; BOCK, 1970; BOSSEMA, 1979; CHETTLEBURGH, 1952, 1955; COLLOPY, 1977; COWIE et al., 1981; HAFTORN, 1954, 1956a, b, c, 1974; KALLANDER, 1978; KILHAM, 1963; MACROBERTS, 1970, 1975; MACROBERTS & MACROBERTS, 1976; SHERRY et al., 1982; SWANBERG, 1951; TOMBACK, 1977; TURCEK & KELSO, 1968; VANDER WALL & BALDA, 1977), the evolution of the behaviour (ANDERSSON & KREBS, 1978; ROBERTS, 1979; TURCEK & KELSO, 1968), and the problem of how in- dividuals recover their caches (BALDA, 1980; BOSSEMA, 1979; KRUSHIN- SKAYA, 1970; SHERRY et al., 1981; TOMBACK, 1980; TURCEK, 1966).
