The European Starling at the upper right is molting from breeding to nonbreeding plumage. The starling still has the completely dark head of breeding plumage, but its bill is dark and it has the numerous white dots of nonbreeding plumage. The starling on the lower left looks like it has completely molted into nonbreeding plumage. August-September is generally when this molting takes place.
