Here's my best guess about the mutations, which might be very wrong. Baby #1: Recessive pied with one or two dark factors. One dark factor is called dark green, two dark factors is called olive. Baby #2: looks a lot like dad and I still don't know exactly what he is. There are several yellowface mutations in budgies and he obviously has one of them. This is a totally different gene than yellowface aka yellowcheek in cockatiels. Yellowface in budgies is a parblue mutation and if you want to know more about that I can deliver the info. For now it's enough to say that it reduces the yellow on the bird but doesn't eliminate all of it. Parblue basically means partial blue. Baby #3: violet is a combination mutation. According to http://www.budgieplace.com/colorsguide.html "Violet factor is a color-adding factor. However, it is not as strong as the grey factor. If a budgie has a violet factor, you may or may not know it. True violet only shows up on cobalt budgies (white-based budgies with one dark factor) or, if double factor, on sky blue budgies(white-based budgies with no dark factor)." So this bird probably has some of those genes. Baby #4: I think I see some hints of green but it's too soon to tell much.

If we go searching on the internet we might find some info on how these mutations affect the cere color of babies. I'm not going to do it tonight though, maybe tomorrow. I found another good budgie mutation site at http://www.budgieplace.com/colorsguide.html They have a picture and description guide similar to the other site, and they also have links where you can call up the technical genetic geek-talk that I love so much. Budgies have a lot more mutations than cockatiels do. The yellowface mutations more or less correspond to pastelface and creamface in cockatiels - they're variations of the blue/whiteface gene which remove some of the yellow/orange color but not all. If you want to get technical, they're alleles of the blue gene and I have an article on allelic mutations from the cockatiel point of view at http://www.littlefeatheredbuddies.com/i ... lelic.htmlCockatiels have two sources of color: yellow/orange pigment and grey pigment. Budgies have both of these pigments plus one more color source that cockatiels don't have: structural color. The structure of the feather reflects light in a way that makes melanin look like blue or green to our eyes. Dark factors and the violet mutation affect the feather structure and makes the color look different, and there's nothing in cockatiels that corresponds to this. The dark factors make the green or blue look darker than normal, and they're co-dominant so a bird with two dark factors will be darker than a bird with one dark factor. Violet changes the feather structure in a way that makes blue color look purplish, and two violet genes have a stronger effect than one. There are more structural mutations than this but these are the ones that seem to be in this family.
