Using the spectral entropy techniques of Powell and Percival, we demonstrate a significant decrease in the spectral entropy of systems defined by both the logistic and Lorenz equations, as the control parameter increases past the initial bifurcation. This decrease in entropy may be related to self-organizing processes and the formation of coherent structures in the laminar to turbulence transition
