### Budgerigar Color Expectation Tables

THE FOLLOWING table concerns the most familiar and therefore most important colors that can be established by the fancier. For instance: Table 1 gives all the possibilities in order to produce the Light Green Budgerigar; Table 2 for the Dark Green phase, etc. See below this table for how to read them. There are 28 varieties/colors to choose.
The "/" in the color means that the bird is split for that color. Light green/white means it is a light green bird split for white.

How to Use the Tables
Behind some of the crossings, percentages are presented: 100%, 50%, 25% and 33 1/3 %. Other percentages, however, are not given, as in such matters complicated theories must first be explained, such as crossing over type I and II. And because those percentages have no meaning for our tables-the correct results are only given behind the most important crossings-we will not go into these technical and often very complicated matters. In Table 1, for instance, you will find the crossing: dark green/white x light green/white; in other words: a crossing of two birds the first of which is dark green in external appearance (phenotype); the second bird light green; both however are split for the color white (or: carrying white as a recessive color). As all the given crossings in the tables are based on a percentage of 100 birds, it should be understood that this crossing only presents the possibility of obtaining a light green Budgie. But, also understandably, not for 100%, as you have a chance of getting young birds of the following colors as well:

```
1. dark green

2. light green/blue

3. dark green/blue

4. light green/yellow

5. dark green/yellow

6. light green/white

7. dark green/white

8. light yellow

9. dark yellow

10. light yellow/white

11. dark yellow/white

12. skyblue

13. cobalt

14. skyblue/white

15. cobalt/white

16. white/blue

17. white cobalt```

Hence: together with the light green bird, eighteen (18) possibilities exist altogether. The following crossing: dark green/white x dark green/ white; gives no less than 27 possibilities, as, besides the 18 just given.

```
19. olive green

20. olive green/blue

21. olive green/yellow

22. olive green/white

23. olive yellow

24. olive yellow/white

25. mauve

26. mauve/white

27. white/mauve```
The crossings with the given percentages present the quickest way to obtain the desired colors. From Table 3, for instance, it becomes obvious that all the young from light green x skyblue are for 100% light green/blue; the same applies when we pair a male skyblue with a light green hen. The second crossing of Table 3 is light green x cobalt; the outcome is 50% light green/ blue, and 50% dark green/ blue. The crossing dark green x light green/ yellow on the other hand presents only 25% dark green/yellow, and further 25% light green, 25% light green/yellow, and 25% dark green/yellow. A sample of crossing dark green x cobalt. Stated is that 33 1/3 % of this crossing will present dark green/ blue; the other possibilities are light green/blue, and olive green/blue, each, of course, for 33 1/3%.

YOU CAN USE THESE TABLES IN A DIFFERENT WAY AS WELL!

You have, for example, a pair of Budgerigars, one of which is light green, the other dark yellow. By checking ALL CROSSINGS light green x dark yellow in the tables you are able to find the outcome, as each table deals with only one given color. From the above crossing you may expect: 50% light green/yellow, and 50% dark green/yellow. A crossing of cobalt x light green/white will present the following possibilities: 1. light green/blue 2. dark green/blue.

Crossing dark yellow x dark yellow/white gives the following possibilities:

```
1. light yellow
2. dark yellow
3. olive yellow
4. light yellow/white
5. olive yellow/white```
