Many egrets are members of the genera Egretta or Ardea which also contain other species named as herons rather than egrets. The distinction between a heron and an egret is rather vague, and depends more on appearance than biology. The word “egret” comes from the French word “aigrette” that means both “silver heron” and “brush”, referring to the long filamentous feathers that seem to cascade down an egret’s back during the breeding season https://en.wikipedia.org/wiki/Egret

The Intermediate Egret is a medium sized white egret. It looks similar to the Great Egret, but is smaller, has a more rounded head and the orange bill is shorter and not so acute angled. The neck is about the same length as the body. In breeding plumage they have deep pink to red bill, blue-green facial skin and long breast plumes and long wing plumes extending beyond the tail.
