I have seen sunflower seeds of type - full black colour or full brown colour or black/grey striped or brown striped. Not sure what is the difference between them and it will be great if anyone can tell me the same. Also which one is better for feeding birds?
Tui Aviary Mix is a blend of fine seed plus the addition of sunflower seed. It is a generic mix that makes it ideal for feeding a mixture of birds from canaries and budgies through to larger cockatiels.
When choosing a seed mix for your birds, go for very best you can get hold of. It should contain a good balance of grass seed, grain, legumes and oily seed (see the lists in the sections below). However, the ideal seed mix isnt to be found in any one type of commercially available budgie food.

This particular example perfectly highlights why Budgie Mix With Sunflower Seeds is so captivating.

Premium seeds, fruits and vegetable Budgie Food. All the ingredients in this Hagen Gourmet Parakeet Seed Mix are selected so you can offer your budgie(s) a fine dining experience. Plus your bird gets the added bonus of all the goodness they need to stay fit and healthy.

A good budgie seed mix is primarily canary grass seed and small millets (white millet, Japanese millet), with smaller amounts of oat groats and perhaps a little flaxseed. Sunflower should be minimal or absent in the base mix.
Jabba used to eat a few sunflower seeds. He has always refused safflower seeds. The only seed mix he likes are the same ones I feed my budgies.
