Two dimensional searching paths exhibit fractal distribution that change with food availability (Normalized Difference Infrared Index, NDII)

•Temporal sequences of foraging searching paths are indicator of food availability.•Searching paths exhibiting a fractal distribution that changes with food availability.•When food is abundant searching paths distribution approaches to a random distribution.•When food is scarce searching paths approaches to an auto-correlated distribution.•Two dimension fractal distribution accurately characterize searching path complexity.
