The birds that dominate this scene in the swampy delta area around the village of Sakasai east of Edo have been accorded special attention, with their wing patterns executed in delicate karazuri embossing. Judging from the bushy crests and yellow bills, the birds are Chinese egrets—a species only rarely seen in the summer in Japan. Far more common was the little egret, with no crest and a black bill. The artist naturally preferred the more decorative species, whether it was to be found in the place or not.
