Hurly, Raleigh Robertson] Summary: To investigate variation in food storing behaviour within a population of red squirrels (Tamiasciurus hudsonicus) we intensively sampled the size and spatial dispersion of hoards. Single-item and large hoards were far more prevalent than expected by chance (Figs. 1 and 2) and appeared to be distinct components of the hoarding tactic employed in this population. Scattered single-item hoards represented more than half of all hoards constructed and approximately one-fifth of all cones stored. Large hoards (> 10 cones) comprised less than 15% of all hoards, and about 50% of all cones stored. In response to experimental manipulations, squirrels altered their hoarding behaviour in order to concentrate cones in the litter and brush heaps we provided, but still scattered a large proportion of their stores. We conclude that hoarding patterns in red squirrels are more variable and plastic than has previously been recognized, and discuss this variability in terms of adaptive explanations.
