Abstract
Sturz & Bodily [1] propose an alternative interpretation for the results presented by Kelly et al. [2], who trained pigeons and chicks in a rectangular environment to find food located in one of two geometrically identical corners. Once the birds were locating the food accurately, they were presented with a novel L-shaped arena. The L-shaped arena provides unique predictions of search behaviour for principal axis-, medial axis- and local geometry-based strategies. The patterns of search behaviour reported support that pigeons were showing primary reliance on the medial axis, whereas chicks showed a primary reliance on local geometrical cues with a secondary reliance on the medial axis.Pubblicazioni consigliate
