The authors show by experiment that the bifurcation accompanying the vortex shedding behind circular cylinders is of the Hopf type, and that the Landau equation (with constants possibly depending on the spatial position) describes the post-critical behavior quite accurately. Typical Landau constant are determined. Finally, the sense in which absolute instability is relevant to the vortex shedding problem is examined.
