Although the game is titled "Bird Week," the flow of seasons make it seem like virtual years are passing by (as opposed to virtual days of a [[week]]). There is no [[winter]] in the game because many of the game's enemies are that of the [[insect]], bird, and small [[mammal]] species. The animated woodland creatures would later provide the inspiration for the dancing daisies on the Super NES video game ''[[Super Mario World 2: Yoshi's Island]]''.<ref name="superfamicom"/>
