Are there any calendars, birds or electronics in The Giver?
The supposed idyllic world of The Giver is characterized by "sameness." The sky is a greyish color when there really is no color; the climate is controlled. With no real sunshine or rain or weather changes, and certainly with no change of seasons, there is no possibility for the existence of many creatures. Birds, for instance, need insects for survival; in addition,without seasonal changes birds would not probably make nests and reproduce because they are gentically programmed for reproductive activities.
In Chapter 3, during the recreational period, the main character Jonas notices an apple that is being tossed changes shape:
Just for an instant. It had changed in mid-air, he remembered. Then it was in his hand, and he looked at it carefully, but it was the same apple. Unchanged.
The idyllic world in which Jonas lives is not real. Time, which is a creation of man in the first place as far as the measurement of minutes and hours, days, weeks, months, etc., has been altered, rearranged in order to fit the new world of "sameness." Such things as electronics which can tap into areas the controlled society wishes to exclude from the ken of its citizens, are excluded by the absence of mention in the narrative.
