Forecasting methods can help estimate many such future aspects of a business operation. The goal of forecasting is to come as close to possible to an accurate picture of the future. But, as with other forms of fortune telling, it can never be fully accurate.
The cere is the fleshy band of tissue containing the nares. Young budgies of all colors start out with a pale bluish or light tan cere, depending on the budgieâs feather color. As they reach sexual maturity, the cere color will usually change.
When they mature, males will have BLUE ceres and when it is breeding season they will turn an even darker blue. Keep in mind that this is for NORMAL parakeets; not lutinos or albinos. In normal female parakeets, the cere can range in colors. The femal's cere may be brown, white, pink, and various shades inbetween. When a female enters breeding season their cere will get a crusty look and will be a dark brown. After breeding season has passed the cere crust will fall off. 8 people found this useful.
