Fig. A1.1. Three representative examples of territories of male Dickcissels (designated by unique four-letter codes corresponding to their colored leg bands) that illustrate how a variable
smoothing parameter selected by the href function is better than one overall smoothing parameter for all birds, because the individual-specific href successfully avoids under- and over-smoothing by taking the location density of each individual into account. Shown are kernel densities of three birds with a smoothing parameter of h = 5, h = 10, and h = 15 as well as the selected smoothing parameter by the href function. Black dots indicate observation locations and dashed lines show a 100% minimum convex polygon overlaid on each kernel density estimate.
