April, May and June are daughters of the sister of Daisy Duck and a duck, both unknown. He admitted that the father of Huey, Dewey, and Louie is the brother of Daisy Duck (a fact not confirmed on the family tree of Don Rosa, where the ducks are among the "family friends"). April, May and June would be cousins of Huey, Dewey and Louie.
Contrary to Huey, Dewey and Louie, who have been virtually adopted by Donald, April, May and June do not live together with the aunt, but simply to visit her occasionally. It can be assumed that they live not far along with their parents, which also do not know anything.
In the 1955 story, Donald and the race of the bridge, they join the female counterparts of Junior Woodchucks.
April, May and June appear in all respects as the female counterpart of Huey, Dewey, and Louie. Here; as Aunt Daisy, which are pretty much the childhood version, bring in the head of the flakes, of different colors together (usually green, blue and red). Their clothing is made from T-shirts, sometimes black, sometimes of colors equal to those of the flakes, and from half-heel shoes, which are also quite similar to those of Paperina.
Image classic April, May and June have no hair, but his head covered with feathers. But sometimes, in the latest stories, to mark most of their femininity, are drawn with blond hair, in which case the hairstyles are different (a door ponytail, another two pigtails on either side of the head, the third one short cut). Apparently, however, nor the colors of flakes or clothes or haircuts unequivocally distinguish the three ducks, which can be considered indistinct characters between them.
From the point of view of the character April, May and June appear undifferentiated. Three ducks intelligent, gentle and feminine, with a developed sense. Nevertheless, there are characteristics of "female" stereotype, such as vanity and love of beauty, which are often a source of conflict with the mentality "male" of Huey, Dewey, and Louie.
- Webby Vanderquack from the animated series DuckTales appears similar to April, May, and June, but has a distinct character and not to be confused with the triplets.
- It has been suggested that the names by which they are known in Italy are diminutives of Emiliana, Eleonora and Evelina; however no story seems to confirm this.
